摘要： An industrial robot comprises a manipulator body structure having a plurality of drive mechanisms for driving the various movements of the robot, and control equipment for controlling and driving the drive mechanisms. Each drive mechanism comprises an electric driving motor and reduction gear. Each control equipment comprises a rectifier and a drive device operatively connected to each driving motor. Each of the drive devices is mounted only on selected areas of the body structure other than the motors, and each of the drive devices is spaced a predetermined distance from its respective motor to which it is operatively connected. The robot body structure thereby functions to absorb the waste heat generated by the drive devices, to spread the waste heat therethroughout, and to transfer the waste heat solely by convection to the ambient air.

摘要： A robot is disclosed in which load torque imposed on motors is reduced and therefore small-sized motors can be used. In the robot, an arm member, a first link, a second link and a third link constitute a parallel linkage, and the first link and the third link are coaxially pivotally supported on a base. With a pivotal shaft for pivotally connecting the second link and the third link, one end of a fourth link having shorter link length than the link length of the third link is pivotally connected to the second and third links and one end of a fifth link having the same link length as that of the fourth link is pivotally connected to the other end of the fourth link. The other end of the fifth link is pivotally supported on the base with a pivotal shaft to which the rotary shaft of the motor is coupled, so that the fifth link can move according to the rotation of the motor.
