The inner workings of the Motoman SK150 robot


The Motoman SK150 Robot

There are several robots on the market that can spot weld, handle material or palletize. However, there are considerably less than can do all three. That is the versatility of the Motoman SK150 robot. This robot, introduced in the mid-1990s, is able to perform all the tasks listed above, and more!  Without its internal parts, – the servomotors, the speed reducers and the wrist unit – the robot would be nothing more than a motionless pile of metal.

The SK-150’s servomotors (part numbers HW9380963-A and HW9380964-A) are integral to the motion of the robot. The motors send power to the gears to put the robot into motion. Without the control of the motors, the SK 150 would be useless to manufacturers.

Along with the servomotors are the speed reducers (part numbers HW9381021-A, HW9380957-A and HW9380958-A) work together to slow the output of energy from the motors and direct it to areas of the robot that need it the most. This teamwork between the motors and the reducers contribute to higher functionality of the robot overall.

Of course, one of the most important pieces of any robot is the wrist assembly (part number HW9171167-1). The wrist assembly is where the end-of-arm tooling is attached.  Without the end effector, many robots would essentially be useless arms. Without the wrist, there is no way to attach the hand.
