Each axis of an industrial robot arm is controlled by:
A)an open-loop servo motor system.
B)a closed-loop servo motor system.
C)an on/off controller.
D)a PID controller.

Question

Quizplus · Accepted Answer

A closed-loop servo motor system is preferred for controlling the axis of an industrial robot arm because it provides feedback control, allowing for accurate positioning and movement of the arm. Open-loop servo motors have no feedback, which can result in inaccuracies or errors in positioning. On/off controllers or PID controllers may be used in conjunction with a closed-loop servo motor system to further improve control and precision.
