Abstract

A surgical system includes a surgical robot with an end effector that supports a drive assembly, a manual interface, and a trigger assembly. A cutting tool is attached to the drive assembly and rotatable about a cutting axis. A method includes positioning, with the surgical robot, the cutting tool relative to a surgical site to align the cutting axis with a predetermined trajectory. A user engages the trigger assembly for rotating the cutting tool about the cutting axis with the drive assembly and advancing the cutting tool along the predetermined trajectory at the surgical site to a first depth. A user applies force to the manual interface for rotating the cutting tool about the cutting axis and advancing the cutting tool along the predetermined trajectory to a second depth greater than the first depth.
