Abstract
A surgical robotic system includes a surgeon console configured to receive user input and a robotic arm configured to hold an instrument drive unit and an instrument coupled to the instrument drive unit. The instrument is controllable in response to the user input and includes an elongate shaft and an end effector coupled to the elongate shaft at a joint. The end effector is configured to pivot about at least one pivot axis relative to the elongate shaft. The instrument also includes a flexible drive rod configured to move longitudinally through the joint and to actuate at least one function of the end effector. The flexible drive rod is disposed off-axis relative to at least one pivot axis of the joint. The system also includes a controller configured to calculate a bend radius of the flexible drive rod during pivoting of the end effector; calculate a compensation distance based on the bend radius; and command the instrument drive unit to advance the flexible drive rod by an actuation distance adjusted by the compensation distance.
