A robot system, in which various pieces of information are exchanged between a tool on a wrist of a robot and a control panel by wireless communication, includes plural storage cells for supplying the tool with power, plural chargers for charging the plural storage cells. An automatic change mechanism is provided on each of the plural storage cells and transfers an associated storage cell from the tool to one of the chargers and vice versa. When the storage cell being placed on the tool runs out of power, the storage cell is returned to a vacant charger to be charged, while another storage cell which has been charged is received on the tool.
