ABSTRACT:
A robot is provided to run so that a trace of the robot efficiently covers a given area according to the detection of a boundary of the area. A spiral pattern running, wherein a radius of the spiral is gradually increased, is started at a desired location in the area and is paused upon the detection of a boundary wall by sensors. Then, a random pattern running, which includes turning to depart from the wall and running forward, is conducted. After the turning has been repeated a predetermined number of times through simulations, the spiral pattern running is resumed at a location spaced from the last turning spot by a predetermined distance or a predetermined length of running time.
