<P>PROBLEM TO BE SOLVED: To obtain a power supply system for a robot, which reconciles the safety and the usefulness of the robot by adjusting its outputtable power, according to the degree of required safety, while materializing a large motor peak current. Ž<P>SOLUTION: This power supply system for robot includes at least one power converting circuit, which includes a plurality of operation modes different in motor output level and gets DC power serving as drive power for motors on each shaft from a commercial AC power source, and a battery, which is charged with electricity from the power converting circuit. In the operation mode large in motor output level among the plurality of operation modes, the output from the battery is connected in parallel with output from the commercial AC power source.
