摘要：
A teleoperated system includes a master grip and a ratcheting system coupled to the master grip. The ratcheting system is configured to be coupled to a slave instrument. The ratcheting system is further configured to align the master grip with the slave instrument by determining a commanded angular velocity for the slave instrument based on a command from the master grip, determining a current alignment error between an alignment of the master grip and an alignment of the slave instrument, and altering the commanded angular velocity for the slave instrument based on the current alignment error. In some embodiments, the ratcheting system is further configured to introduce a control system error to alter the commanded angular velocity. In some embodiments, the current alignment error is a rotation angle error between the alignment of the master grip and the alignment of the slave instrument.
