Description
図1〜3は、例示的な自律網羅型ロボット100の上方斜視図、下方斜視図、および分解組立図を示す。ロボット100は、シャーシ102、駆動システム104、縁部掃除ヘッド106a、および制御装置108を有する。駆動システム104は、シャーシ102に搭載され、ロボット100を操縦するように構成された差動式駆動装置(ロボットの中心直径に近接するかまたはその直径の上にあり、別個に速度制御可能な左輪および右輪)である。縁部掃除ヘッド106aは、ロボット100の下方およびその直近の汚れおよびゴミを除去するために、さらに具体的にはロボットが前方向で掃除するときに汚れおよびゴミを主掃除ヘッド106bの掃除経路の中へ掃き込むために、シャーシ102の側縁を越えて延びるように取り付けられる。幾つかの実施態様では、主または縁部掃除ヘッド106b、106aは、表面処理を施すためにも使用可能である。制御装置108(図9Aにも図示されている)は、シャーシ102によって担持され、自律的様態で床を掃除または処理するために、下で説明するように、センサ読取り値または指示に基づいて指令をロボット100の構成要素に供給する行動規範型ロボットシステムによって制御される。蓄電池109がロボット100およびその副システム用の電源となりうる。底蓋110は、ロボット100の内側部分を保護しかつ汚れおよびゴミを締め出すことができる。
