What motion type moves the TCP in a straight line from the start position to the destination point?

The motion type that moves the TCP (Tool Center Point) in a straight line from the start position to the destination point is classified as linear motion. In robot programming, linear motion is fundamental as it ensures that the movement is direct and predictable, which is essential for tasks that require precision, such as assembly or welding.

Linear motion allows for consistent and repeatable paths, making it ideal for applications where the exact trajectory is necessary. This type of movement is distinct from others like circular, which involves movement along a curved path, or arc, which also implies a segment of a circular path. Random motion, on the other hand, does not follow any specific trajectory and is more erratic, making it unsuitable for tasks requiring precision and accuracy.

Understanding linear motion is crucial for programming robots effectively, as it directly affects the control and execution of tasks where straight paths are essential for performance.
