AI Technical Summary
Existing technologies struggle to accurately locate vibration sources and effectively suppress vibrations in flexible robotic arms, especially in multi-degree-of-freedom, strongly coupled systems. Existing methods rely on analytical models and are difficult to adapt to the time-varying characteristics of the system.
By constructing an excitation trajectory to collect joint response data, using cross-correlation coefficients and time delay analysis to locate the vibration source, and combining flexible joint dynamic characteristic modeling and data-driven compensation, time-varying input shaping is achieved to suppress vibration.
It enables rapid and reliable positioning of the main vibration-excited joints in a flexible robotic arm, and significantly reduces residual end-effector vibration by adaptively updating the input shaper, thereby improving operational stability and safety.
