Robotics I Honors Practice Exam

A pick and place robot never has rotary motion.

False True Depends on the task Only in 3D

Correct Answer:

False

Explanation:

Rotational motion is often part of a pick-and-place robot because orienting the grasped object is usually as important as reaching its location. A rotating wrist or gripper lets the end effector adjust the angle of the part so it can be picked up reliably from racks or conveyors and placed into a fixture or bin with the correct orientation. Even systems that mainly translate in x, y, and z typically include some rotary joint at the end effector to control orientation. So the statement claiming no rotary motion ever is not correct.
