Insect Cyborgs: Towards Precision Movement
The experiments involved the researchers keeping the body of the stick insects fixed, and electrically stimulating one of three leg muscles to produce walking-like movements.

Researchers in Japan and Germany have explored how electrical stimulation in stick insects' leg muscles relate to the resulting torque for enabling precise motor control of hybrid insect-computer robots.
The researchers kept the insects' bodies fixed and stimulated one of three leg muscles to generate walking-like motions; the muscles enable propulsion, joint stiffness, and transitions between standing and swinging the leg.
Dai Owaki at Japan's Tohoku University said, "Based on our measurements, we could generate a model that predicted the created torque when different patterns of electrical stimulation were applied to a leg muscle."
