Computer-controlled

Computer-controlled artificial legs have aided in improving amputees' freedom of movement by mimicking the natural motion of their missing limbs. Now, a new robotic ankle promises to make this motion even more precise by dynamically adjusting to the terrain underfoot.

Researchers at Michigan Technological University are developing a microprocessor-controlled prosthetic leg with an ankle that lets the foot tilt up and down and roll from side to side. It is said to allow for a more stable walking gait.
