What are the three different motion types?

• A. MOVS (spiral) and MOVA (arc) with MOVJ
• B. MOVJ (joint motion), MOVL (linear), MOVA (arc)
• C. MOVJ (joint motion), MOVL (linear), MOVC (circular)
• D. MOVJ (joint motion), MOVP (plane), MOVC (circular)

Answer: (D)

In Motoman programming, motion types describe how the robot moves between points. The three distinct motion types you use to plan paths are joint motion, planar motion, and circular interpolation. Joint motion (MOVJ) moves each axis toward the target, resulting in a path driven by the combination of all axis motions. Planar motion (MOVP) keeps the movement within a defined plane, which lets you guide a tool along a flat surface or along a plane-defined path. Circular interpolation (MOVC) makes the end effector follow a circular arc between points, defined by a center or radius.

Choosing MOVJ for joint motion with MOVP for plane motion and MOVC for circular interpolation captures these three fundamental motion types, so this combination is the best match. Other options mix in linear or spiral/arc concepts that aren’t grouped as the three core motion types in this context, making them less representative of the standard three-motion categorization.
