1. A method for verifying positional accuracy of a tracking reference device, said method comprising:
storing in non-transient storage memory a position of a verification mark located on a bone with respect to a coordinate frame of a tracking reference device affixed to the bone; and
a robotic device moving an end-effector to align a longitudinal axis of the end-effector with a longitudinal axis of the verification mark to verify positional accuracy of the tracking reference device.
