Abstract
A rotary trowel is provided for a working robot which can freely run and the concreted floor is flattened and finished by the rotary trowel while the robot runs on the concreted floor. The working robot is automatically operated in accordance with a zigzag running pattern which was set in a desired working range which is determined by a width and a depth. When the teaching mode is set, the first straight running and the first turning operation of a zigzag running pattern which will be set are executed by the manual operation. Thus, a straight running distance and turning direction which were detected by the manual operation are set as initial values and the zigzag running pattern is automatically set. Subsequently, the automatic operation is performed in accordance with the zigzag running pattern which was automatically set.
