Abstract

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. An end effector of the surgical tool is coupled to a tool driver. An actuator is driven by a motor of the tool driver and configured to drive a degree of freedom of the end effector. One or more processors are configured to receive a position command describing a desired position for the end effector, translate the desired position to a command for a joint associated with the end effector, calculate a compensation term to compensate for a source of hysteresis for backlash and/or compliance, and send a motor command for the motor coupled with the actuator based on the compensation term and the command for the end effector.
