Abstract:
A motor-driven movable body (510) comprises an output shaft (531) and a plurality of motors (571, 572) for driving the output shaft. This motor-driven movable body executes multiple drive control for assigning at least two of the plurality of motors to a driving state, and when the multiple drive control is executed and any one of the plurality of motors is determined to be abnormal, executes single drive control for assigning only one of the plurality of motors to the driving state and assigning the other motors to a stopped state. While the single drive control is being executed, this motor-driven movable body identifies the abnormal drive motor on the basis of a predetermined quantity of state correlating with the driving state of the drive motor assigned to the driving state.
