摘要:
A teleoperated system includes a master grip and a ratcheting system coupled to the master grip. The ratcheting system is configured to align the master grip with a slave instrument commanded by the master grip by determining grip rotation values describing an orientation of the master grip, determining instrument rotation values describing an orientation of the instrument, determining an orientation error between an orientation of the master grip and the orientation of the instrument based on the grip rotation values and the instrument rotation values, and reducing the orientation error by low pass filtering the grip rotation values or the instrument rotation values.
