Bionic Super-Suit HAL Promises Not To Lock The Pod Bay Doors

A robot suit has been developed that could help older people or those with disabilities to walk or lift heavy objects.

Dubbed HAL, or hybrid assistive limb, the latest versions of the suit will be unveiled this June at the 2005 World Expo in Aichi, Japan, which opened last month. A commercial product is slated for release by the end of the year…

Two control systems interact to help the wearer stand, walk and climb stairs. A “bio-cybernic” system uses bioelectric sensors attached to the skin on the legs to monitor signals transmitted from the brain to the muscles. It can do this because when someone intends to stand or walk, the nerve signal to the muscles generates a detectable electric current on the skin’s surface. These currents are picked up by the sensors and sent to the computer, which translates the nerve signals into signals of its own for controlling electric motors at the hips and knees of the exoskeleton. It takes a fraction of a second for the motors to respond accordingly, and in fact they respond fractionally faster to the original signal from the brain than the wearer’s muscles do…
