Explain Teach Pendant programming and how it is typically used.

• A. A handheld interface to manually control and program a robot, enabling on-line programming, jog moves, and recording routines.
• B. A stationary computer used to run offline simulations only.
• C. A sensor that measures torque for safety.
• D. A protective enclosure around the robot.

Answer: (A)

Teaching with a teach pendant means using a handheld control unit connected to the robot controller to guide and record the robot’s movements. The pendant lets you physically jog the arm to reach precise poses and orientations, then save those positions as steps in a program. This on-line programming approach lets you test and refine motions in real time, capture routines, and build automation sequences directly at the robot.

Because it’s a handheld interface, you can quickly adjust paths, set waypoints, and control basic I/O or timing while the robot is connected, making it ideal for teaching tasks like pick-and-place or assembly. It’s also common to later transfer the learned program to the controller or a PC for storage and deployment, whereas offline programming on a computer (not the pendant) is used to create more complex simulations before uploading.

The other options don’t fit because a stationary computer, a torque sensor, or a protective enclosure aren’t how teach pendant programming is described or used.
