The Robot Suit HAL (Hybrid Assistive Limb) has been designed and built by Cyberdyne Inc. with assistance from researchers around the country. It’s described by its makers as a cyborg-type robot meant to supplement human muscles or to assist in their rehabilitation. Its part handrail, part sensor and part hydraulically controlled machinery. A patient stands between two handrails, holding on, while sensors are affixed to the skin of the legs. The sensors pick up nerve signals which are sent to an onboard computer. Those signals are then converted to action by small motors and power units that cause the muscle to be worked in the same way it would be were the person’s body able to move it on their own. The end result is a direct connection between nerve signals and movement, which the researchers believe, will result in faster and perhaps better recovery for the patient.
