Robotic surgical systems and methods for guiding a tool along a path using hybrid automated/manual control. A manipulator supports a surgical tool and a sensor measures forces/torques applied to the tool. A control system commands the manipulator to perform an automated advancement of the tool along a predetermined tool path in a first path direction and according to a predetermined feed rate. During the automated advancement, an input is received from the sensor in response to user applied forces/torques to the tool. The control system evaluates an effect of the sensor input on the automated advancement of the tool to determine an effective feed rate and an effective path direction for the tool with respect to the tool path. The control system determines a commanded action for the manipulator and the tool with respect to the tool path based on the effective feed rate and effective path direction.

A machine-learned model is used in the detection of anomalies in operation of the instrument drive chain of a surgical robotic system. For example, normal operation (e.g., cable force) based on operation information (e.g., position and/or load) is predicted by the machine-learned model, which prediction is then compared to actual operation. The comparison results in early detection of anomalies based on machine-learned prediction and the corresponding incorporation of historical operation.
