In comparison with robot manipulators, primate limbs excel robots in facile movements requiring compliance control. Based on this fact, this paper will extend our findings in modeling the muscle-reflex mechanism of primate limbs to robotic control. After some salient properties of the neuromuscular system were identified, a neuromuscular-like model that can accurately emulate different involuntary and voluntary movements was developed. To link the findings from the biological system to robotic control, the developed neuromuscular-like controller was implemented on a PUMA 560 robot. The experimental results demonstrated that the emulated spindle-reflex model in the neuromuscular-like controller acts as an impedance to any changing displacement and will comply and enhance the needed compliant forces or torques for the changing motion. Due to this force-enhancement property, no external force sensor is required for sensing force feedback in this control. The capability in performing various free and constrained movements demonstrated that a neuromuscular-like control is very useful for robotic applications requiring adaptation.
