A teach pendant is described as?

• A. A large desktop computer
• B. An electronic device, hand-held, to control and program a robot
• C. A remote control with no programming capability
• D. A type of sensor

Answer: (B)

A teach pendant is a handheld, portable device used to control and program a robot. It acts as the operator’s interface to the robot controller, letting you move the arm in small increments (jogging), save positions as you teach the robot where to go, and assemble simple programs by recording a sequence of moves. Its handheld form and programming capability distinguish it from other devices: it’s not a desktop computer meant for general tasks, it’s not just a remote control with no programming features, and it’s not a sensor. In practice, you might guide the robot to a part, store that pose as a waypoint, and then repeat or combine multiple steps to create a programmed path.
