Why do high-speed robots require jerk-limited motion planning?

Asked on Nov 05, 2025

Answer

High-speed robots require jerk-limited motion planning to ensure smooth transitions in acceleration, which reduces mechanical stress and improves precision. Jerk-limited profiles help prevent abrupt changes in force that can cause vibrations, wear, and tear on mechanical components, leading to more reliable and accurate robotic operations.

Example Concept: Jerk-limited motion planning involves controlling the rate of change of acceleration (jerk) to create smooth motion profiles. By limiting jerk, robots can transition more smoothly between different speeds and accelerations, reducing the risk of mechanical shock and improving the overall stability and accuracy of high-speed operations. This is particularly important in applications like pick-and-place tasks, CNC machining, and robotic assembly where precision and repeatability are critical.

Additional Comment:

Jerk-limited profiles are often implemented in motion controllers and path planners used in industrial robotics.
These profiles can be generated using polynomial functions or spline-based approaches to ensure continuous derivatives of position, velocity, and acceleration.
Limiting jerk is crucial for maintaining the longevity of robotic components and ensuring the safety of high-speed operations.
