Abstract
An electric power supply device on a mobile vehicular apparatus includes an AC generator, a rectifier connected to the AC generator, for rectifying an electric current generated by the AC generator, a regulator connected to the rectifier, for maintaining the voltage with respect to the rectified electric current at a constant level, the regulator being connected to a power line for transmitting the electric current at the constant-level voltage to a DC electric actuator on a master control arm, and a battery connected to the power line. The master control arm controls a slave manipulator arm for processing or handling a workpiece. When the DC electric actuator is subjected to a large load and needs a large amount of electric power, the battery discharges and supplies the stored electric energy to the DC electric actuator.
