ABSTRACT:
An industrial robot is disclosed in which inertia is reduced and backlash substantially eliminated by mounting motors for the first and second movable arms on a stationary stand, and transmitting torque to the second arm by means of timing belts. A harmonic gear mechanism arranged at the juncture of the first and second arms reduces the speed of the output timing pulley. The belt arrangement requires no lubrication and is lighter and much quieter in operation than previous torque transmitting arrangements.
