- 本体ケースと、
この本体ケースを走行させる駆動輪と、
この駆動輪を駆動させるモータと、
前記本体ケースに設けられ、この本体ケースの前方に向けて超音波を発信する送波手段と、
前記本体ケースにて前記送波手段の両側にそれぞれ設けられ、前記送波手段から発信された超音波の反射波を受信する受波手段と、
前記モータの駆動を制御することで前記本体ケースを自律走行させる制御手段とを具備し、
前記制御手段は、互いに異なる複数の閾値が設定され、前記送波手段から所定時間毎に発信された超音波が物体に当たって反射した反射波の前記各受波手段による受信の有無および受信するまでの時間に基づいて検出した前記物体と前記各受波手段とのそれぞれの距離とこれら複数の距離に基づいて検出した前記本体ケースに対する前記物体の方向と前記各距離と前記各閾値とのそれぞれの比較結果の組み合わせに基づく前記本体ケースに対する前記物体の位置関係に応じて前記モータの駆動を制御する
ことを特徴とした自律走行体。 - 制御手段は、各受波手段によりそれぞれ検出した物体との距離と各閾値とを比較して前記物体への接近を判断したときに本体ケースを減速または停止させるようにモータの駆動を制御する
ことを特徴とした請求項1記載の自律走行体。
