A miniature surgical robot and a method for using it are disclosed. The
miniature surgical robot attaches directly with the bone of a patient.
Two-dimensional X-ray images of the robot on the bone are registered with
three-dimensional images of the bone. This locates the robot precisely on
the bone of the patient. The robot is then directed to pre-operative
determined positions based on a pre-operative plan by the surgeon. The
robot then moves to the requested surgical site and aligns a sleeve
through which the surgeon can insert a surgical tool.
