ABSTRACT:
According to a legged mobile robot of the present invention, a variable measuring portion101measures the changing amount of a secondary desired angle θT2, namely, of the newest primary desired angle θT1that is received by a first sub-control unit121as a variable δ. When a determining portion102determines that an absolute value of the variable δ exceeds a threshold ε, a correcting portion103corrects a motor current I so as to inhibit the changing amount of the motor current I. Thereby, even when an abnormality is temporarily generated in the communication between a main control unit110and a first sub-control unit121via a first communication line and the absolute value of the variable δ exceeds a threshold ε, the current supply I to a motor131is inhibited from changing rapidly.
