1. A surgical robotic system comprising:
a robot having a base, a robot arm, and an end-effector;
a guide tube coupled to the end-effector of the robot;
a compliant orthopedic driver for driving a bone screw into a bone of a patient configured to be positioned within a guide tube, the complaint orthopedic driver comprising:
a body extending from a proximal end to a distal end along a driver axis;
a driver tip disposed at the distal end of the body and having a mechanical interface adapted to mate with a head of the screw to allow rotation of the bone screw by rotation of the body around the driver axis,
wherein the body includes a first compliant portion configured to allow the driver to flex about at least a first axis and a second axis, the first and second axes are transverse to the driver axis, the driver tip being rotationally fixed to the body around the driver axis,
wherein the first compliant portion includes a first pair of blade hinges having a first blade and a second blade, wherein the second blade is disposed adjacent and distal to the first blade along the driver axis,
wherein the first compliant portion flexes about the first axis, the first axis extending along the first blade and flexes about the second axis, the second axis extending along the second blade.
