SUPPLYING METHOD FOR POWER OF FREE-TRAVELING TYPE ROBOT

摘要

PURPOSE:To reduce a weight and a size and to improve the mobility of a robot by supplying power from a power supply terminal near the maximum length of a power cable in a moving direction. CONSTITUTION:A floor-traveling type robot 3a couples a power reception terminal 1 of the robot with a power supply terminal 2 disposed at a position P1 by a manipulator 31 of the rotor, and moves at a desired position by supplying the power. At this time, the robot 3a draws out a power cord 24 from an automatic winder 4 to travel. The robot 3a which has completed a predetermined work moves to next working position. At this time, when the robot judges that the cord 44 is short, the robot searches a power supply terminal 2 disposed at the position P2 being nearest to the next working position within a range of the maximum length of the cord 24, and moves to the position P2.
