Patent attributes
Techniques for active and semi-active damping include a system including a base, a first linkage, a second linkage, and a processor. A proximal end of the first linkage is coupled to the base. The first linkage is configured to support a first instrument. The first linkage includes a first link, a second link, and a first damper coupling the second link to the first link. A proximal end of the second linkage is coupled to the base. The second linkage is configured to support a second instrument. The second linkage incudes a third link, a fourth link, and a second damper coupling the fourth link to the third link. The processor is configured to detect a movement or vibration of the first linkage caused by motion of the second linkage and control the second linkage to mitigate the detected movement or vibration of the first linkage.
