Abstract: Surgeons are required advanced techniques and experiences to handle the cutting device correctly. The lack of these may bring on over cuts and damages to the surrounding tissue. This situation has risks of causing the subsequent complications or life-threatening accidents by heavy bleeding and nerve damage. To solve these problems that can happen to any surgeons, we developed a remote controlled haptic robot drilling system. The force and position of robots are transmitted in both directions by bilateral control. Pine and Balsa woods were attached and used as phantoms of cortex and marrow of the bone. They were drilled continuously and the value of the force scaling function was calculated from the maximum motor torque and the cutting force by using computer. The drill could successfully stopped within safe position from the position limitation. Higher accuracy was expected by fine adjustment in force scaling.
