Abstract
An exemplary system and method for homing a surgical tool are provided. In general, a surgical tool can include an end effector, an elongate shaft, and a wrist that couples the end effector to a distal end of the shaft can be configured to facilitate movement of the end effector relative to the shaft. The surgical tool can be coupled to a robotic surgical system featuring an imaging device and a processor. Through the use of closed-loop feedback and machine vision techniques, the end effector can be calibrated into a home position to ensure precise and accurate movement of the end effector when in use by a surgeon.
