US Patent 12070287 Robotic surgical tools having dual articulation drives

A control circuit for use with a robotic surgical system. The control circuit is configured to receive a parameter indicative of a rotary position of an articulation motor. The articulation motor is configured to drive an articulation joint of a robotic surgical tool, wherein the articulation motor is configured to move through a first range of positions and a second range of positions. The control circuit is further configured to implement a first operating state, and implement a second operating state when the parameter corresponds to a transition of the articulation motor from the first range of positions to the second range of positions. The control circuit is further configured to re-implement the first operating state when the parameter corresponds to a return of the articulation motor from the second range of positions into the first range of positions by a threshold anti-dither angle.
