ABSTRACT:
An industrial robot has a robot unit (10) comprising a fixed base (12) and movable robot components (16, 18, 20) operatively controlled by driving motors (M.theta., MW, MU, M.alpha., M.beta., M.gamma.) provided with absolute position detecting encoders (EC.theta., ECW, ECU, EC.alpha., EC.beta., EC.gamma.). The swivel body (16) among the movable robot components, mounted on the fixed base (12) is mounted, on its mount, with the driving motor (M.theta.) for operatively controlling the same, and is mounted with and holds a battery (46) for supplying a backup voltage to the encoders of the driving motors (MW, MU, M.alpha., M.beta., M.gamma.) for operatively controlling the movable robot components (18, 20). The battery is connected electrically by cables (48, 49) to the encoders (EC.theta., ECW, ECU, EC.alpha., EC.beta., EC.gamma.).
