The Fundamentals of the Motoman UP165 Robot


The Motoman UP165Like many robots in the Motoman line, the UP165 is a complex piece of machinery that has more parts than you would realize. Like each Motoman robot, the UP-165 has servomotors, internal wiring and other parts that help the robot to move. However, it is the makeup of the wrist in the Motoman UP 165 that allows the robot to perform its job accordingly. The wrist unit, part number HW917 is made up of the wrist and the wrist base.

The wrist base, part number HW9100890-1, is the part of the robot that attaches the wrist to the rest of the robot at the B-axis. This wrist base routes the wiring from the wrist through the rest of the robot and down to the controller. Then there is the wrist, part number HW9100896-1, that give motion to any end-of-arm tooling attached to the robot. The wrist has 360 motion and acts like a human wrist, with the end-of-arm tooling acting as the hand.

As mentioned above, a robot is not all wrist though. There are internal wires, servomotors and reducers as well.

Internal wires for the Motoman UP-165, part number HW9171094-A, are the wires that direct all of the outside current to the different motors and other parts of the robot. This internal wiring eventually connects to the controller and the power supply for the robot, feeding it not only power, but also instructions for its applications.

Servomotors, another integral part of the robot’s makeup, are found on each axis of the Motoman UP-165: The S-axis, HW9381382-A; the L- and U-axes, HW9381261-A; the R-axis, HW9380938-A; and the B- and T-axes, HW9381368-A. These servo-motors are important because they help with robot movement. They are like regular AC motors, but they have an amplifier and receive feedback from other points on the robot.

Finally, each robot has reducers, also known as speed reducers, on every axis: The S-axis, part number HW9381388-A; the L-axis, part numbers HW9381442-A and HW9381442-B; the U-axis, part numbers HW9381465-A and HW9381465-C; the R-axis, part number HW9381399-A; the B-axis, part number HW9380961-A; and the T-axis, part number HW9381400-A. These reducers are used to slow the output from the motors in the robot axes.

It is important for all these critical parts of the robot to work together for a complete system that works well for the customer and improves productivity in their facility.
