Abstract
It is so arranged in a robot as to monitor the over-current state of each motor and that of two more than two motors when put together by seeing the total current value of the motors being monitored in parallel with absorption of both the static load torque and the dynamic load torque of each actuator/motor. Additionally, it is so arranged as to check if each of the predetermined unit members including the arm sections and the leg sections of the robot is in an over-current state or not and also if the entire robot is in an over-current state or not, while each of the motors are not in an over-current state.
