Which two motion types are mentioned in the context of changing motion type?

• A. MOVJ and MOVL
• B. MOVP and MOVQ
• C. MOVR and MOVS
• D. MOVJ and MOVK

Answer: (A)

In Motoman programming, changing motion type typically means choosing between how the robot moves: by moving its joints or by moving the end effector along a straight line. A joint move, encoded as MOVJ, drives the individual joints to reach the target, which can be faster but doesn’t guarantee a straight-line path in Cartesian space. A linear (Cartesian) move, encoded as MOVL, guides the end effector along a straight line, ensuring a direct path in space. When the question refers to changing motion type, it’s pointing to these two ways of moving—MOVJ for joint-space motion and MOVL for linear Cartesian motion. The other option pairs involve different motion commands that aren’t the standard joint-versus-linear contrast.
