Dynamic Calibration

Definition

Dynamic calibration refers to the process of adjusting a robotic system's parameters to ensure accurate and reliable performance during motion and dynamic tasks. This method is essential for enhancing the precision of a robot's movements by accounting for factors such as inertia, friction, and external disturbances that occur during operation. By performing dynamic calibration, robotic systems can adapt to real-time conditions and improve their overall efficiency in assembly and manipulation tasks.
