MOVC stands for which type of motion?

• A. Joint motion
• B. Linear motion
• C. Circular motion
• D. Angular motion

Answer: (C)

MovC is the circular interpolation command in Motoman programming. It makes the end effector travel along a circular arc from the start point to the end point, defined by a circle’s center (or by through points) rather than simply moving in a straight line or moving each joint independently. This lets you create smooth curved motions, which is essential for tasks that require rounding corners or following curved contours. Linear motion would go straight between points, and joint motion moves joints to reach the target without enforcing a specific spatial arc, so they don’t produce the same curved path. Angular motion isn’t a standard path type for a Cartesian arc, so circular motion best fits the described capability.
