Motion
Jerk
Jerk is the rate of change of acceleration, and limiting it produces smoother starts and stops on a robot path.
High jerk shows up as a sharp jolt at the beginning or end of a move, which can shake a payload loose or excite mechanical resonance.
Modern controllers apply jerk limiting or S-curve profiles so acceleration ramps up and down gradually instead of stepping instantly.
