1. A new attempt to “nurture a programming brain” What is the best first step for children to learn programming? The inventor's research started with this question. I tried to teach children how to program using various tools, but every tool always causes one child to drop out. I want to lose it.

  In order to fulfill such a wish, the device devised by the inventors as a new tool for programming learning is an apparatus named “PETS”.

  The PETS is configured to be movable (eg, using wheels). Moreover, PETS is comprised so that a some block can be mounted | worn. There are five types of blocks, for example, “go forward”, “go backward”, “turn right”, “turn left”, and “loop”. Children are given the task of moving the PETS from the starting point to the goal point for a given course. The children think for themselves what kind of blocks should be attached to the PETS and in what order, and try to run the PETS after actually attaching the blocks to the PETS. Repeat the mistakes. Through such trial and error, children are trying to “nurture their programming brain” by learning programming.

  Through this study, PETS has been found to be effective for “nurturing programming brains” for children (for example, elementary school children or preschool children), but the target for “nurturing program brains” is limited to children. Not. PETS is expected to be effective for “nurturing the programming brain” or “activating the programming brain” of people of all ages, including the elderly.

2. Basic Configuration of Programming Learning Device (“PETS”) FIG. 1A is a perspective view showing an appearance of a programming learning device (“PETS”) 10 according to one embodiment of the present invention. The apparatus 10 includes a block mounting portion 60 configured to mount a plurality of blocks 20 (not shown in FIG. 1A, see FIG. 1B). Specifically, the block mounting portion 60 has a plurality of openings 30 formed therein. A plurality of blocks 20 can be mounted on the block mounting portion 60 by mounting each block 20 in each opening 30. The apparatus 10 is configured to be movable according to the type and order of the blocks 20 mounted on the block mounting unit 60.

  Here, in the example shown in FIG. 1A, the block mounting portion 60 is formed on the upper surface of the apparatus 10, and the block mounting portion 60 mounts the 12 blocks 20 at the maximum in the 12 openings 30. However, the configuration of the block mounting portion 60 is not limited to this. The block mounting portion 60 may be formed on a surface other than the upper surface of the apparatus 10, or the block mounting portion 60 may be mounted in any number of the openings 30. You may make it comprise. Furthermore, in the example shown in FIG. 1A, the device 10 is configured to be movable using two wheels, but the configuration of the device 10 is not limited to this. For example, the apparatus 10 is configured to be movable using an arbitrary moving means such as a four-wheel wheel, an endless track, a bipedal leg, a quadruped leg instead of a two-wheeled wheel. You may do it.

  FIG. 1B is a perspective view showing the appearance of the plurality of blocks 20. There are five types of blocks, such as “go forward”, “go backward”, “turn right”, “turn left”, and “loop”, but are not limited thereto. The plurality of blocks 20 can include any type of block.

  FIG. 1C is a top view of a “go forward” block, a “go backward” block, a “turn right” block, a “turn left” block, and a “loop” block. As shown in FIG. 1C, an arrow is formed on the upper surface of each block. Thus, it is possible to easily recognize visually which block is which type of block. Specifically, an arrow pointing forward is formed on the upper surface of the “go forward” block, and an arrow pointing backward is formed on the upper surface of the “go backward” block. An arrow pointing to the right is formed on the upper surface of the “turn” block, an arrow pointing to the left is formed on the upper surface of the “turn left” block, and a loop is formed on the upper surface of the “loop” block. An arrow pointing is formed.

  Here, in the example shown in FIG. 1C, the contour shape of the upper surface of each block is formed such that the upper side of the page represents “front” and the lower side of the page represents “rear”. The contour shape of the upper surface is not limited to this. As long as it is possible to distinguish between “front” and “back” of each block, each block can have an arbitrary shape. In addition, each block is preferably configured so that it can be attached to the opening of the block attachment part only in one direction.

3. Basic Operation of Programming Learning Device (“PETS”) FIG. 2 is a top view of the device 10. The apparatus 10 includes a block mounting portion 60 configured to be able to mount a plurality of blocks 20. The block mounting unit 60 includes a sequential processing block mounting unit (first block mounting unit) 70 for defining sequential processing, and a loop processing block mounting unit (second block mounting unit) for defining loop processing. ) 80. In the example shown in FIG. 2, nine of the twelve openings 30 are used as the openings 30 of the sequential processing block mounting portion (first block mounting portion) 70, The remaining three openings 30 of the openings 30 are used as the openings 30 of the loop processing block mounting portion (second block mounting portion) 80, but are not limited thereto. The sequential processing block mounting part 70 may have any number of openings 30, and the loop processing block mounting part 80 may also have any number of openings 30. The device 10 also has a start button 50. When the start button 50 is pressed, the operation of moving the device 10 according to the types and order of the plurality of blocks 20 attached to the device 10 is started.

  The solid arrows shown in FIG. 2 indicate the order in which the blocks 20 mounted in the opening 30 of the sequential processing block mounting unit 70 are executed. That is, the blocks 20 mounted on the sequential processing block mounting unit 70 define sequential processing executed in the order indicated by the solid arrows. The broken-line arrows shown in FIG. 2 indicate the order in which the blocks 20 mounted in the opening 30 of the loop processing block mounting unit 80 are executed. That is, the blocks 20 mounted on the loop processing block mounting unit 80 define loop processing to be executed in the order indicated by the dashed arrows.

3.1 Operations Related to Sequential Processing FIG. 3A is a perspective view showing an appearance of the apparatus 10 in a state where the three blocks 20 are respectively mounted in the three openings 30 of the sequential processing block mounting portion 70. .

  FIG. 3B is a top view of the device 10 in the state shown in FIG. 3A. The leftmost block 20 is a “go forward” block. The central block 20 is a “turn right” block. The rightmost block 20 is a “go forward” block.

  As shown in FIGS. 3A and 3B, when the start button 50 of the apparatus 10 is pressed in a state where the three blocks 20 are mounted in the three openings 30 of the sequential processing block mounting unit 70, respectively. The apparatus 10 moves according to the type and order of the blocks 20 mounted on the sequential processing block mounting unit 70. Specifically, the apparatus 10 determines that the block 20 mounted in the first opening 30 of the sequential processing block mounting unit 70 is a “forward” block, and in response to this determination, moves forward. Move (step 1). Next, the apparatus 10 determines that the block 20 mounted in the second opening 30 of the sequential processing block mounting section 70 is a “turn right” block, and responds to this determination so as to turn right. (Step 2). Next, the apparatus 10 determines that the block 20 mounted in the third opening 30 of the sequential processing block mounting unit 70 is a “forward” block, and moves forward in response to this determination. (Step 3).

  It should be noted that the positions of the first, second, and third openings 30 of the sequential processing block mounting portion 70 are predetermined. In the example shown in FIG. 3B, the first opening 30 is the leftmost opening 30 in the bottom row and the second opening 30 in the order indicated by the solid arrow shown in FIG. Is the second opening 30 from the left in the bottom row and the third opening 30 is the third opening 30 from the left in the bottom row, but is not limited thereto. It is also determined in advance how far the apparatus 10 moves forward when moving forward. The distance is, for example, a distance corresponding to one square of the course, but is not limited to this. Further, the angle at which the device 10 turns right when the device 10 turns right is also determined in advance. The angle is, for example, 90 °, but is not limited thereto.

  Hereinafter, with reference to FIGS. 4A to 4D, as shown in FIGS. 3A and 3B, the three blocks 20 are mounted in the three openings 30 of the sequential processing block mounting portion 70, respectively. How the apparatus 10 moves on the given course 400 when the start button 50 of the apparatus 10 is pressed will be described. Here, it is assumed that the given course 400 is composed of 3 × 3 squares, and the start point is the lower left square of the given course 400.

  FIG. 4A shows that in response to the device 10 determining that the block 20 attached to the first opening 30 is a “forward” block, the device 10 is one cell forward from the starting point. (Step 1).

  FIG. 4B shows the mass after the device 10 has moved in step 1 in response to the device 10 determining that the block 20 attached to the second opening 30 is a “turn right” block. In the same square, a state of moving 90 ° to the right is shown (step 2).

  FIG. 4C shows the mass after device 10 has moved in step 2 in response to device 10 determining that block 20 attached to third opening 30 is a “forward” block. Then, a state of moving forward by one square is shown (step 3).

  FIG. 4D shows the state after the device 10 has moved in step 3.

  In this way, when the start button 50 is pressed in a state where the three blocks 20 are respectively mounted in the three openings 30 of the sequential processing block mounting portion 70, the three blocks 20 are supported. Steps 1, 2, and 3 described above are sequentially executed. The user can experience the state in which the above-described steps 1, 2, and 3 corresponding to the three blocks 20 are sequentially executed by observing the movement of the device 10 as shown in FIGS. 4A to 4D. It is possible to learn to.

  In order to distinguish between a step being executed and a step not being executed, it is preferable to distinguish between a block 20 corresponding to a step being executed and a block 20 corresponding to a step not being executed. This is achieved, for example, by preventing light from being emitted from the block 20 corresponding to the step not being executed, while light is emitted from the block 20 corresponding to the step being executed. The block 20 itself may be a light emitter, but in consideration of cost and power consumption, light from one or more light sources (for example, one or more LED light sources) built in the block mounting unit 60 (for example, The block mounting portion 60 and the block 20 are preferably configured such that (red light) is emitted to the outside through the block 20. For example, you may make it form the arrow part of the upper surface of the block 20 with a permeable material.

  The top view of the apparatus 10 shown in FIG. 4A shows that the block 20 is running by emitting light from the block 20 corresponding to step 1. The top view of the apparatus 10 shown in FIG. 4B shows that the block 20 is executing by emitting light from the block 20 corresponding to step 2. The top view of the apparatus 10 shown in FIG. 4C shows that the block 20 is running by emitting light from the block 20 corresponding to step 3. The top view of the apparatus 10 shown in FIG. 4D shows a state where the execution of the program is completed by emitting light from all of the blocks 20. In the top views shown in FIGS. 4A to 4D, the part indicated by the black arrow indicates the part from which light is emitted.

  Similarly, the block mounting unit 60 and the block 20 are configured to indicate at least one of mounting completion of the block 20, initial state of program execution, error display, and the like by blinking of light emitted from the block 20. May be.

3.2 Operations Related to Loop Processing FIG. 5A shows that one block 20 is mounted in one opening 30 of the sequential processing block mounting portion 70, and two blocks 20 are loop processing block mounting portions 80. It is a perspective view which shows the external appearance of the apparatus 10 of the state with which each two opening part 30 was mounted | worn.

  FIG. 5B is a top view of the device 10 in the state shown in FIG. 5A. The block 20 mounted on the sequential processing block mounting unit 70 is a “loop” block. The left block 20 mounted on the loop processing block mounting unit 80 is a “go forward” block, and the right block 20 is a “turn right” block.

  As shown in FIG. 5A and FIG. 5B, one block 20 is mounted in one opening 30 of the sequential processing block mounting portion 70, and two blocks 20 are two in the loop processing block mounting portion 80. When the start button 50 of the apparatus 10 is pressed in the state where each of the openings 30 is mounted, the apparatus 10 detects the blocks mounted on the sequential processing block mounting section 70 and the loop processing block mounting section 80. Move according to type and order. Specifically, the apparatus 10 determines that the block 20 mounted in the first opening 30 of the sequential processing block mounting section 70 is a “loop” block, and repeats the loop processing in response to this determination. . The type of loop processing is defined according to the type and order of blocks mounted on the loop processing block mounting unit 80. Specifically, the “loop processing” includes the “forward” block 20 mounted in the first opening 30 of the loop processing block mounting unit 80 and the second opening of the loop processing block mounting unit 80. 30 is defined by a “turn right” block 20 attached to 30.

  The number of times the loop process is repeated is determined in advance. In the example shown in FIG. 5B, the description will be made assuming that the number of times the loop is repeated is not limited to this. The number of times the loop process is repeated may be any number (for example, a three-time loop, a five-time loop, etc.). In particular, the loop processing may be repeated once. In this case, since the loop process is not repeated, the process is equivalent to a so-called subroutine. Alternatively, a plurality of types of “loop” blocks having different numbers of loops, such as a “1 loop” block, a “2 loop” block, a “3 loop” block, and a “5 loop” block may be provided. .

  Hereinafter, with reference to FIGS. 6A to 6E, as shown in FIGS. 5A and 5B, one block 20 is mounted in one opening 30 of the sequential processing block mounting section 70, and two blocks are mounted. When the start button 50 of the apparatus 10 is pressed while the 20 is mounted in each of the two openings 30 of the loop processing block mounting section 80, how the apparatus 10 moves on the given course 600. Explain how to move to. Here, it is assumed that the given course 600 is composed of 3 × 3 squares, and the start point is the lower left square of the given course 600.

  In response to determining that the block 20 mounted in the first opening 30 of the sequential processing block mounting section 70 is a “loop” block, the apparatus 10 repeats the loop processing.

  FIG. 6A shows that a block 20 in which the apparatus 10 is defined as the first block of the first loop processing (that is, the block 20 mounted in the first opening 30 of the loop processing block mounting portion 80) is shown. It is determined that the block is a “go forward” block, and in response to this determination, a state of moving forward by one square from the start point is shown (step 1).

  FIG. 6B shows that the block 10 in which the apparatus 10 is defined as the second block of the first loop processing (that is, the block 20 mounted in the second opening 30 of the loop processing block mounting portion 80) is shown. It is determined that the block is a “turn right” block, and in response to this determination, the same square as the square after moving in Step 1 is shown to move to turn right by 90 ° (Step 2).

  FIG. 6C shows that the block 10 in which the apparatus 10 is defined as the first block of the second loop processing (that is, the block 20 mounted in the first opening 30 of the loop processing block mounting portion 80) is shown. It is determined that the block is a “forward” block, and in response to this determination, a state in which the block moves forward by one square from the square after moving in step 2 is shown (step 3).

  FIG. 6D shows that the block 10 in which the apparatus 10 is defined as the second block of the second loop processing (that is, the block 20 attached to the second opening 30 of the loop processing block attachment portion 80) is shown. It is determined that the block is a “turn right” block, and in response to this determination, the same square as the square after moving in Step 3 is shown to move to turn right by 90 ° (Step 4).

  FIG. 6E shows the state after the device 10 has moved in step 4.

  In this way, one block 20 is mounted in one opening 30 of the sequential processing block mounting section 70, and two blocks 20 are mounted in the two openings 30 of the loop processing block mounting section 80. When the start button 50 is pressed in the mounted state, the loop processing called from one block 20 (that is, the loop processing defined by the two blocks 20) is performed a predetermined number of times (for example, two times). ) Minutes, repeated. The user can empirically learn how the loop processing called from one block 20 is repeatedly executed by observing the movement of the device 10 as shown in FIGS. 6A to 6E. Is possible.

  Even during the loop processing, in order to distinguish between the step being executed and the step not being executed, the block 20 corresponding to the step being executed is distinguished from the block 20 corresponding to the step not being executed. Is preferred. This is achieved, for example, by preventing light from being emitted from the block 20 corresponding to the step being executed, but not from the block 20 corresponding to the step not being executed. The block 20 itself may be a light emitter, but in consideration of cost and power consumption, light from one or more light sources (for example, one or more LED light sources) built in the block mounting unit 60 (for example, The block mounting portion 60 and the block 20 are preferably configured such that (red light) is emitted to the outside through the block 20. For example, you may make it form the arrow part of the upper surface of the block 20 with a permeable material.

  The top view of the apparatus 10 shown in FIG. 6A shows that the block 20 corresponding to step 1 is being executed by emitting light from the block 20 corresponding to step 1. The top view of the apparatus 10 shown in FIG. 6B shows that the block 20 corresponding to step 2 is being executed by emitting light from the block 20 corresponding to step 2. The top view of the apparatus 10 shown in FIG. 6C shows that the block 20 corresponding to step 3 is being executed by emitting light from the block 20 corresponding to step 3. The top view of the apparatus 10 shown in FIG. 6D shows that the block 20 corresponding to step 4 is being executed by emitting light from the block 20 corresponding to step 4. The top view of the apparatus 10 shown in FIG. 6E shows that the execution of the program has been completed by emitting light from all of the blocks 20. In the top views shown in FIGS. 6A to 6E, a portion indicated by a black arrow indicates a portion where light is emitted.

  Similarly, the block mounting unit 60 and the block 20 are configured so as to indicate at least one of mounting completion of the block 20, initial state of program execution, error display, and the like by blinking of light emitted from the block 20. You may do it.

3.3 Operations Related to Branch Processing FIG. 7 shows the color sensor 100 mounted on the bottom surface 90 of the apparatus 10. The color sensor 100 detects the color of the surface facing the bottom surface 90 of the apparatus 10 and outputs a signal indicating the detected color. The apparatus 10 executes a branch process according to a signal output from the color sensor 100. However, it is assumed that the color sensor 100 is activated only when the apparatus 10 moves in response to a “forward” block or a “backward” block.

  8A to 8D, in the state where the three blocks 20 are respectively mounted in the three openings 30 of the sequential processing block mounting portion 70 as shown in FIGS. 3A and 3B, The following describes how the apparatus 10 moves on the given course 800 when the start button 50 of the apparatus 10 is pressed. Here, the given course 800 is composed of 3 × 3 squares, and the color of the central square of the 3 × 3 squares is red (indicated by diagonal lines in FIGS. 8A to 8D). Assume that the color of the square is white and that the starting point is the lower left square of the given course 800.

  FIG. 8A shows that, in response to the device 10 determining that the block 20 attached to the first opening 30 is a “forward” block, the device 10 is one cell ahead of the starting point. (Step 1). The apparatus 10 determines a signal output from the color sensor 100 in the mass after moving in Step 1. In this case, since the signal output from the color sensor 100 is a signal indicating “white”, the apparatus 10 continues the processing.

  FIG. 8B shows that the device 10 has moved in step 1 in response to determining that the block 20 attached to the second opening 30 is a “turn right” block. In the same square, a state of moving 90 ° to the right is shown (step 2).

  FIG. 8C shows the mass after device 10 has moved in step 2 in response to the device 10 determining that the block 20 mounted in the third opening 30 is a “go forward” block. Then, a state of moving forward by one square is shown (step 3). The apparatus 10 determines a signal output from the color sensor 100 in the square after moving in Step 2. In this case, since the signal output from the color sensor 100 is a signal indicating “red”, the apparatus 10 performs the first process (that is, the process corresponding to the block 20 attached to the first opening 30). Branch immediately before). As a result, the apparatus 10 re-executes steps 1 to 3 from the square after moving in step 3.

  FIG. 8D shows that in response to determining that the block 20 attached to the first opening 30 is a “forward” block by re-execution of step 1, the device 10 is (Step 4). The apparatus 10 determines a signal output from the color sensor 100 in the square after moving in Step 4. In this case, since the signal output from the color sensor 100 is a signal indicating “white”, the apparatus 10 continues the processing.

  In this way, when the start button 50 is pressed in a state where the three blocks 20 are respectively mounted in the three openings 30 of the sequential processing block mounting portion 70, the three blocks 20 are supported. Steps 1, 2, and 3 described above are sequentially executed, and it is determined whether or not to execute the branch process depending on whether or not the color detected by the color sensor 100 satisfies a predetermined condition. The user can empirically learn how the branch process is executed by observing how the device 10 moves as shown in FIGS. 8A to 8D.

  Note that the condition to be satisfied for executing the branch process and the branch destination of the process when the condition is satisfied are not limited to the example described above. For example, the condition to be satisfied for executing the branching process may be “when the signal output from the color sensor 100 is a signal indicating“ blue ”” or “the signal output from the color sensor 100”. May be a signal indicating “green”. Furthermore, the branch destination of the process when the condition is satisfied may be an arbitrary point of the process. For example, the branch destination of the process when the condition is satisfied may be “return to the previous process” or “return to the previous process”.

  In addition, a sensor other than the color sensor can be used instead of the color sensor 100 described above. Such a sensor may be any sensor as long as it detects information outside the device 10 and outputs a signal indicating the detected information. In addition, such a sensor can be mounted at any location of the device 10 as long as information outside the device 10 can be detected.

4). Processing of Programming Learning Device (“PETS”) As described with reference to FIG. 1A, the device 10 moves the device 10 according to the type and order of the blocks 20 mounted on the block mounting unit 60. To control. Such control is performed by the control unit 200. The control unit 200 is housed in the housing of the apparatus 10 (for example, the housing 10a shown in FIG. 11).

  FIG. 9 is a block diagram illustrating an example of the configuration of the control unit 200. The control unit 200 includes a processor unit 210, a memory unit 212, a block attachment detection circuit 220, a sensor output circuit 230, a light source driving circuit 240, and a motor driving circuit 250.

  The processor unit 210 controls the overall operation of the apparatus 10. The memory unit 212 stores a program required for executing processing, data required for executing the program, and the like. Here, it does not matter how the program is stored in the memory unit 212. For example, the program may be preinstalled in the memory unit 212. Alternatively, the program may be installed in the memory unit 212 by being downloaded through a network such as the Internet, or may be installed in the memory unit 212 through a storage medium such as an optical disk or a USB. May be. The program stored in the memory unit 212 is, for example, a program that executes the above-described sequential processing, loop processing, and branch processing. The processor unit 210 reads a program stored in the memory unit 212 and executes the program. As a result, the apparatus 10 can move according to the type and order of the blocks 20 mounted on the block mounting unit 60.

  The block mounting detection circuit 220 is connected to the block mounting unit 60 (see FIG. 1A). The block mounting detection circuit 220 detects that the block 20 is mounted on the block mounting unit 60 and outputs a signal indicating a voltage corresponding to the type of the block 20 mounted on the block mounting unit 60 to the processor unit 210. To do.

  The sensor output circuit 230 is connected to the output of the color sensor 100. The sensor output circuit 230 outputs a signal indicating the output of the color sensor 100 to the processor unit 210.

  The light source driving circuit 240 controls blinking of light emitted from the light source by driving the light source (for example, LED) in accordance with a command from the processor unit 210. Thereby, blinking of light (for example, red light) emitted from the block 20 is controlled.

  The motor drive circuit 250 is connected to the motor 252. The motor drive circuit 250 drives the motor 252 in accordance with a command from the processor unit 210. By driving the motor 252, the rotational force of the motor 252 is transmitted to the wheels 256 via the gear mechanism 254. The device 10 can move as the wheel 256 rotates. In this case, the gear mechanism 254 can be omitted when the rotational force of the motor 252 is directly transmitted to the wheels 256. As a power source for the motor 252, for example, a battery (not shown) can be used.

  Note that the components included in the control unit 200 shown in FIG. 9 may be configured by a single hardware component or may be configured by a plurality of hardware components. The configuration of the control unit 200 is not limited to a specific hardware configuration.

  10A to 10C are flowcharts illustrating an example of a procedure of processing executed by the processor unit 210. This process is stored in the memory unit 212 in the form of a program, for example. The processor unit 210 reads a program stored in the memory unit 212 and executes the program.

  The processing executed by the processor unit 210 includes preprocessing steps (steps 1001 to 1004), sequential processing steps (steps 1005 to 1010), branch processing steps (steps 1011 to 1015), and loop processing steps (steps 1016 to 1016). 1022).

4.1 Preprocessing steps (steps 1001 to 1004)
The preprocessing step starts from step 1001. In step 1002, the processor unit 210 determines whether or not the start button 50 has been pressed. Unless the start button 50 is pressed, the processing of the processor unit 210 does not proceed from step 1002. When the start button is pressed, the process proceeds to step 1003.

  In step 1003, the processor unit 210 detects the type and order of the blocks 20 mounted on the block mounting unit 60, and stores the detected information in a block list. Specifically, the processor unit 210 detects the type and order of the blocks 20 mounted on the sequential processing block mounting unit 70, stores the detected information in the sequential processing block list, and for loop processing. The type and order of the blocks 20 mounted on the block mounting unit 80 are detected, and the detected information is stored in a loop processing block list. Each of the sequential processing block list and the loop processing block list is a list indicating which types of blocks are mounted in what order.

  For example, when nine openings 30 are formed in the sequential processing block mounting portion 70, the sequential processing block list includes nine pockets. Each pocket corresponds to the block 20 mounted in the opening 30 formed in the sequential processing block mounting section 70. A value indicating the type of the detected block 20 is stored in each pocket of the sequential processing block list in accordance with the order of the detected blocks 20.

  For example, when the three opening portions 30 are formed in the loop processing block mounting portion 80, the loop processing block list includes three pockets. Each pocket corresponds to the block 20 mounted in the opening 30 formed in the loop processing block mounting portion 80. A value indicating the type of the detected block 20 is stored in each pocket of the loop processing block list in accordance with the order of the detected blocks 20.

  The processor unit 210 executes processing according to these block lists.

  In step 1004, the processor unit 210 executes a process of initializing variables. Specifically, the following operations are executed: j = 1, k = 1, l = 1, length A = length of the sequential processing block list, and length B = length of the loop processing block list.

4.2 Sequential processing steps (steps 1005 to 1010)
In step 1005, the processor unit 210 compares the value of j with the value of length A to determine whether or not the inequality j ≦ length A is satisfied. If the determination result in step 1005 is “Yes”, the process proceeds to step 1006. If the determination result in step 1005 is “No”, the process proceeds to step 1010, and the sequential processing step ends.

  In step 1006, the processor unit 210 determines which type of block the j-th block of the loop processing block list is. If it is determined that the j-th block in the sequential processing block list is a “loop” block, the process proceeds to step 1016 for the loop processing step. If it is determined that the j-th block in the sequential processing block list is not a “loop” block, the process proceeds to step 1007.

  In step 1007, the processor unit 210 executes an operation corresponding to the j-th block in the sequential processing block list.

  In step 1008, the processor unit 210 determines what type of block the j-th block of the loop processing block list is. If it is determined that the j-th block in the sequential processing block list is a “go forward” block or a “go backward” block, the process proceeds to step 1011 for a branch process step. If it is determined that the j-th block in the sequential processing block list is neither a “go forward” block nor a “go backward” block, the process advances to step 1009.

  In step 1009, the processor unit 210 increments the value of the variable j by 1 (j = j + 1). Thereafter, the processing returns to Step 1005. In this way, the process repeats steps 1005 to 1009 until the determination result in step 1005 becomes “No”.

4.3 Branch processing steps (steps 1011 to 1015)
In step 1011, the processor unit 210 performs an operation corresponding to the block, and then determines whether the signal output from the color sensor 100 is a signal indicating "red" or a signal indicating "blue" or "green". Or a signal indicating “white”.

  If it is determined that the signal output from the color sensor 100 is a signal indicating “red”, in step 1012, the processor unit 210 sets the value of j to 1. Thereafter, the processing returns to Step 1005.

  If it is determined that the signal output from the color sensor 100 is a signal indicating “blue”, in step 1013, the processor unit 210 decrements the value of j by 2 (j = j−2). Thereafter, the processing returns to Step 1005.

  If it is determined that the signal output from the color sensor 100 is a signal indicating “green”, in step 1014, the processor unit 210 decrements the value of j by 3 (j = j−3). Thereafter, the processing returns to Step 1005.

  If it is determined that the signal output from the color sensor 100 is a signal indicating “white”, in step 1015, the processor unit 210 increments the value of j by 1 (j = j + 1). Thereafter, the processing returns to Step 1005.

4.4 Loop processing steps (steps 1016 to 1022)
In step 1016, the processor unit 210 sets the number of times n to be repeated by the “loop” block. Here, n may be a predetermined value or a value set by a “loop” block. For example, when “loop twice”, n = 2 is set.

  In step 1017, the processor unit 210 compares the value of l with the value of n to determine whether or not an inequality of l ≦ n holds. If the determination result in step 1017 is “Yes”, the process proceeds to step 1018. If the determination result in step 1017 is “No”, the process proceeds to step 1005.

  In step 1018, the processor unit 210 compares the value of k with the value of length B to determine whether or not the inequality k ≦ length B is satisfied. If the determination result in step 1018 is “Yes”, the process proceeds to step 1020. If the determination result in step 1018 is “No”, in step 1019, the processor unit 210 increments the value of l by 1 (l = 1 + 1). Thereafter, the processing returns to Step 1017.

  In step 1020, the processor unit 210 executes an operation corresponding to the kth block in the loop processing block list.

  In step 1021, the processor unit 210 determines which type of block the k-th block of the loop processing block list is. If it is determined that the k-th block in the loop processing block list is a “go forward” block or a “go backward” block, the process proceeds to step 1011. If it is determined that the k-th block in the loop processing block list is neither a “go forward” block nor a “go backward” block, the process proceeds to step 1022.

  In step 1022, the processor unit 210 increments the value of k by 1 (k = k + 1). Thereafter, the processing returns to Step 1018. In this way, the process repeats steps 1018 to 1022 until the determination result in step 1018 becomes “No”.

5. The internal structure of the device for programming learning ( "PETS") 11 is an exploded perspective view showing an example of the internal structure of the apparatus 10.

  The apparatus 10 includes a block mounting portion 60 configured to be able to mount a plurality of blocks 20. The block mounting part 60 is attached to the housing 10a. The block mounting part 60 includes a block guide substrate 62 and a block mounting substrate 64.

  A plurality of openings 30 are formed in the block guide substrate 62. The block guide substrate 62 is disposed on the block mounting substrate 64 so as to face the block mounting substrate 64. A block mounting region 120 is formed in a portion of the block mounting substrate 64 that faces the opening 30 of the block guide substrate 62. Here, the opening 30 is configured such that the block 20 is mounted in the block mounting region 120 with reference to the direction in which the apparatus 10 moves forward.

5.1 Before explaining details of the internal structure of the structural device 10 of the block 20, details of the structure of the block 20 will be explained.

  FIG. 12A is a perspective view of the block 20 shown in FIG. 1B as viewed obliquely from above.

  FIG. 12B is a perspective view of the block 20 shown in FIG. 1B as viewed obliquely from below.

  As shown in FIGS. 12A and 12B, the block 20 includes a front wall 21, a back wall 22, a right side wall 23, a left side wall 24, and a top wall 25. The front wall 21 is a wall facing the direction in which the apparatus 10 moves forward when the block 20 is mounted on the block mounting portion 60. The back wall 22 is a wall that faces in a direction in which the apparatus 10 advances backward when the block 20 is mounted on the block mounting portion 60. The right side wall 23 is a wall located on the right side when viewed from the front wall 21 side. The left side wall 24 is a wall located on the left side when looking forward from the front wall 21 side. The top wall 25 is a wall located on the upper end side of the front wall 21, the back wall 22, the right side wall 23, and the left side wall 24.

  Here, a slit 23 a is formed at the lower end of the right side wall 23. Further, a notch 23 b is formed at the lower end edge of the right side wall 23. The top wall 25 is provided with a notation 27 indicating the type of the block 20. The notation section 27 shows the contents of instructions by individual blocks. Further, a resistor 26 having a resistance value indicating the type of the block 20 is attached to the lower end of the front wall 21. The type of the block 20 can be electrically detected by the voltage generated based on the resistor 26.

  Furthermore, it is preferable that the block 20 is configured so that the directionality of the block 20 is recognized from the appearance. For example, as shown in FIG. 12B, the width of the front wall 21 of the block 20 may be wider than the width of the rear wall 22 of the block 20. In addition or alternatively, as shown in FIG. 12A, the contour shape of the upper surface wall 25 may be formed so that “front” and “back” of the block 20 can be distinguished. Good. Thereby, it is possible to distinguish between “front” and “rear” of the block 20 from the appearance of the block 20. Therefore, it is also possible to distinguish the “right” and “left” of the block 20 from the appearance of the block 20.

5.2 Block guide substrate 62
FIG. 13A is a top view showing the opening 30 formed in the block guide substrate 62.

  FIG. 13B is a top view showing a cross-sectional structure of the BB line portion of the block 20 shown in FIG. 12A.

  FIG. 13C is a top view showing the opening 30 together with the cross-sectional structure of the BB line portion of the block 20 in a state where the block 20 is inserted into the opening 30.

  The opening 30 formed in the block guide substrate 62 includes an opening front edge 31 a located on the front side of the apparatus 10 with respect to the center of the opening 30, and a position behind the apparatus 10 with respect to the center of the opening 30. And an opening right edge 33a and an opening left edge 34a located on the left and right sides of the opening 30. The opening 30 has a substantially isosceles trapezoidal shape when the opening front edge 31a is the upper bottom and the opening rear edge 32a is the lower bottom.

  The opening front edge 31a has a shape in which the central portion is recessed forward. A rear edge protruding portion 32 a 1 that protrudes to the inside of the opening 30 is formed in the central portion of the opening rear edge 32 a. Further, a right protruding portion 33a1 protruding toward the inside of the opening 30 is formed in a portion adjacent to the opening front edge 31a of the opening right edge 33a, and adjacent to the opening front edge 31a of the opening left edge 33a. A left protruding portion 34 a 1 that protrudes to the inside of the opening 30 is formed in the portion to be performed.

  As with the block 20, the opening 30 is preferably configured such that its directionality is recognized from its appearance. For example, as illustrated in FIG. 13A, the opening 30 may have a shape that is symmetrical in the left-right direction and asymmetric in the front-rear direction. Thereby, it is possible to distinguish between “front” and “back” of the opening 30 from the appearance of the opening 30. Therefore, it is also possible to distinguish “right” and “left” of the opening 30 from the appearance of the opening 30.

  Furthermore, the block 20 and the opening 30 are preferably configured such that the block 20 can be inserted into the opening 30 only in one direction. For example, as illustrated in FIG. 13C, the block 20 and the opening 30 are configured such that the front wall 21 of the block 20 contacts the opening front edge 31 a of the opening 30 and the back wall 22 of the block 20 is the opening 30. Even if the block 20 can be inserted into the opening 30 only when the block 20 is aligned with the opening 30 in a mode of contacting the rear edge 32a of the opening. Good. Thereby, it is possible to prevent the block 20 from being inserted into the opening 30 in the wrong direction.

  When the block 20 is inserted into the opening 30, the right side wall 23 of the block 20 abuts on the right protruding portion 33 a 1, and the left side wall 23 of the block 20 abuts on the left protruding portion 34 a 1, thereby opening the block 20. Positioned in the left-right direction within the portion 30. Further, when the block 20 is inserted into the opening 30, the right edge of the front wall 21 of the block 20 abuts on the right edge of the opening front edge 31 a of the opening 30, and the left edge of the front wall 21 of the block 20. Is brought into contact with the left end of the opening front edge 31a of the opening 30, and the back wall 22 of the block 20 is brought into contact with the rear edge protruding portion 32a1 of the opening rear edge 32a of the opening 30, whereby the block 20 is It is positioned in the front-rear direction within the opening 30.

  Thus, the shape of the opening 30 of the block guide substrate 62 is such that the edge of the opening 30 is in point contact with the side wall of the block 20 inserted into the opening 30 so that the block 20 is positioned front and rear, left and right. It is configured.

  Thus, the resistance when the block 20 is inserted into the opening 30 is reduced by reducing the contact area between the block 20 inserted into the opening 30 of the block guide substrate 62 and the inside of the opening 30. Can do.

5.3 Block mounting board 64
The block mounting substrate 64 is a substrate for mounting the block 20. In the example shown in FIG. 11, the block mounting board 64 has twelve block mounting areas 120, but is not limited to this. The block mounting substrate 64 can have any number of block mounting areas 120. The block mounting substrate 64 is configured such that one block 20 is mounted in each block mounting area 120.

5.4 Block mounting area 120
FIG. 14 is an enlarged perspective view of a portion A (a portion including one block mounting region 120) shown in FIG.

  Around the block mounting area 120, a front support column 65a with which the front wall 21 of the block 20 abuts, a rear support column 65b with which the back wall 22 of the block 20 abuts, and a right support with which the right side wall 23 of the block 20 abuts. A support column 65c and a left support column 65d with which the left side wall 24 of the block 20 abuts are provided. Here, a leaf spring 63 is attached to the right support column 65c as a spring member that engages with the slit portion 23a and the notch portion 23b formed in the right side wall 23 of the block 20. Here, the notch portion 23b is provided at the end of the side wall so that the distance that the block 20 moves with respect to the leaf spring 63 in the state where the spring member and the block 20 are in contact with the side wall of the block 20 is reduced. It is desirable that it is cut from the portion to the front of the slit portion 23a. In the block mounting area 120, when the block 20 is mounted in the block mounting area 120, a pair of resistance connection terminals 66 a and 66 b are brought into contact with the resistor 26 attached to the lower end portion of the front wall 21 of the block 20. Is attached. Further, the block mounting area 120 is provided with a light emitting element for causing the block mounting area 120 to shine when the block 20 is mounted on the block mounting area 120. The light emitting element 241 is, for example, a light emitting diode. However, the light emitting element 241 is not limited to a light emitting diode. The light emitting element 241 may be any device as long as it can notify that the block 20 is mounted by light emission when the block 20 is mounted in the block mounting area 120.

  FIG. 15A is a perspective view showing a state in which the block 20 is positioned on the block mounting area 120.

  FIG. 15B is a perspective view showing a state in which the block 20 is mounted in the block mounting area 120.

  Hereinafter, a state in which the block 20 is mounted on the block mounting substrate 64 will be described with reference to FIGS. 15A and 15B.

  As shown in FIG. 15A, when the block 20 is inserted into the opening 30 of the block guide substrate 64 and pushed downward, the block 20 is mounted on the corresponding block mounting area 120 as shown in FIG. 15B. It becomes a state. In this state, the front wall 21, the rear wall 22, and the left side wall 24 of the block 20 are in contact with the front support column 65a, the rear support column 65b, and the left support column 65d that are located around the block mounting region 120. The right side wall 23 of the block 20 is pressed by a plate spring 63 attached to the right support column 65c, and a part of the plate spring 63 is engaged with the slit portion 23a of the right side wall 23. As a result, the block 20 is held in the block mounting area 120. Further, in this state, the pair of resistance connection terminals 66a and 66b provided in the block mounting region 120 are brought into contact with the resistor 26 attached to the back side of the front wall 21 of the block 20, and this pair of resistance connection is made. The resistor 26 is connected between the terminals 66a and 66b.

  Hereinafter, when the block 20 is attached to and detached from the block mounting region 120, the state in which the engagement state between the slit portion 23a and the notch portion 23b of the block 20 and the plate spring 63 of the block mounting substrate 64 changes will be specifically described. To do.

5.5 Mounting of Block 20 FIGS. 16A to 16E show the relationship between the slit portion 23 a and the notch portion 23 b of the block 20 and the plate spring 63 of the block mounting substrate 64 when the block 20 is mounted on the block mounting substrate 64. The state in which the combined state changes is shown from the state before the block mounting is started to the completion of the block mounting. 16A to 16E, the block guide substrate 62 is not shown.

  As shown in FIG. 16A, the block 20 is disposed on the block mounting area 120, and the block 20 passes through the opening 30 of the block guide substrate 62 and approaches the block mounting area 120.

  Since the notch 23b is formed at the lower end of the right side wall 23 of the block 20, the right side wall 23 is a leaf spring until the upper end of the notch 23b contacts the leaf spring 23b as shown in FIG. 16B. 63 does not touch.

  Thereafter, as shown in FIG. 16C, when the block 20 is further brought closer to the block mounting area 120, the leaf spring 63 is placed on the right side between the notch portion 23b and the slit portion 23a thereon, as shown in FIG. 16D. The leaf spring 23b presses the right side wall 23b for the first time by riding on the surface wall 23b.

  When the block 20 is brought closer to the block mounting area 120, the leaf spring 63 is engaged with the slit portion 23a located on the notch portion 23b as shown in FIG. 16E.

  Thus, since the notch part 23b is formed in the lower end of the right side wall 23 of the block 20, as shown in FIG. 16B, the right side wall until the upper end of the notch part 23b contacts the leaf spring 23b. Since 23 does not contact the leaf spring 63, when the block 20 is attached to the block attachment region 120, the distance to push the block 20 against the leaf spring 63 can be shortened.

5.6 Removal of Block 20 FIGS. 17A to 17E show the engagement between the slit portion 23 a and the notch portion 23 b of the block 20 and the leaf spring 63 of the block mounting substrate 64 when the block 20 is removed from the block mounting substrate 64. The state changes from the state before block removal to the completion of block removal. 17A to 17E, the block guide substrate 62 is not shown.

  As shown in FIG. 17A, when the block 20 is lifted so as to be pulled out from the block mounting area 120, the leaf spring 63 is positioned on the right side between the notch 23b and the slit 23a above it as shown in FIG. 17B. By climbing onto the face wall 23b, it is possible to obtain a response that the engagement between the slit portion 23a and the leaf spring 23b is disengaged.

  Thereafter, as shown in FIG. 17C, when the block 20 is further lifted so as to be pulled out from the block mounting region 120, the leaf spring 63 enters the notch 23b formed at the lower end of the right side wall 23 of the block 20, The leaf spring 63 is in contact with the upper edge of the notch 23b. In this state, as shown in FIG. 17C, an upward force is applied to the block 20 by the leaf spring 23b, and a feeling that the block 20 is lifted is obtained. In this state, the block 20 naturally moves upward without giving a force for pulling out the block 20.

  Thereafter, in a state in which the force from the leaf spring 23b to the upper edge of the notch 23b does not reach, as shown in FIGS. 17D and 17E, the block 20 is lifted upward to remove the block 20 from the block guide substrate 62. Can be pulled out from.

  When the block 20 is lifted so as to be pulled out from the block mounting area 120 in this manner, the leaf spring 63 is formed at the lower end of the right side wall 23 of the block 20 after the engagement between the leaf spring 63 and the slit portion 23a is released. Since the notch 23b is inserted into the block 20, an upward force is exerted on the block 20 by the leaf spring 23b, so that the block 20 can be lifted.
