Summary:To provide a traveling robot system for enabling surrounding operators to easily recognize a cause of stopping and an obstacle to be removed while automatically stopping an unmanned carrier in the case of predicting that the unmanned carrier interferes with the obstacle.SOLUTION: A traveling robot system determines whether or not an object detected by an object detection sensor is an obstacle arranged in a travel possible area of an unmanned carrier (step S3), calculates a scheduled passing area of the unmanned carrier along a scheduled travel route V in the case of determining the obstacle arranged in the travel possible area (step S4), predicts whether or not the unmanned carrier interferes with the obstacle on the basis of the calculated scheduled passing area and position information of the obstacle output by the object detection sensor (step S5), and stops the unmanned carrier and makes a robot execute obstacle designation operation for pointing out the obstacle in the case of predicting that it interferes with the obstacle (steps S7 and S8).SELECTED DRAWING: Figure 5 【課題】無人搬送車が障害物と干渉すると予測される場合には無人搬送車を自動的に停車させつつ、その停車の原因及び除去すべき障害物を周囲の作業者に容易に認識させることが可能な走行ロボットシステムを提供する。【解決手段】走行ロボットシステムは、物体検出センサにより検出された物体が、無人搬送車の走行可能領域に配置された障害物であるか否かを判定し(ステップS3)、走行可能領域に配置された障害物であると判定した場合には、走行予定経路Vに沿った無人搬送車の通過予定領域を算出し(ステップS4)、算出した通過予定領域と、物体検出センサより出力された障害物の位置情報とを基に、無人搬送車が前記障害物と干渉するか否かを予測し(ステップS5)、干渉すると予測した場合には、無人搬送車を停車させるとともに、ロボットに当該障害物を差し示す障害物指定動作を実行させる(ステップS7及びS8)。【選択図】図5
