Abstract
A base end portion of a lower arm is mounted on a revolutionarily drivable revolution portion at a specific offset from the revolutionary axis thereof, and an upper arm is mounted in the lower arm, with the lower and upper arms being rotationally drivable within a plane parallel to the revolutionary axis. In a motor casing, three motors for driving three dimensional motions of a wrist are disposed in a vertical direction with their axes being in parallel. Since the upper arm is offset from the revolutionary axis, both right-handed operation and left-handed operation can be easily selected, and the work range of this robot can be increased while its installation space can be reduced. The lower arm has a motor for driving the upper arm at the lower part thereof apart from a gearbox for the upper arm. Power of the motor for driving the upper arm is transmitted to the gearbox through a power transmission member. Such structure enables to reduce thickness of the lower arm.
