At University of Tsukuba, Yoshiyuki Sankai, professor of Cybernics, unveils a robot suit entitled HAL (Hybrid Assistive Limb), with a 60kg anti radiation jacket, in Tsukuba city, Ibaraki prefecture.
HAL robot suits, developed by Cyberdyne, detect signals from the brain to assist in the wearer's movement, and were developed for disabled and handicaped people.

Functional Description
"When a person attempts to move, nerve signals are sent from the brain to the muscles via motoneuron, moving the musculoskeletal system as a consequence.
At this moment, very weak bio-signals can be detected on the surface of the skin. "HAL" catches these signals through a sensor attached on the skin of the wearer.
Based on the signals obtained, the power unit is controlled to move the joint unitedly with the wearer's muscle movement, enabling to support the wearer's daily activities.
This is what we call a 'voluntary control system' that provides movement interpreting the wearer's intention from the biosignals in advance of the actual movement.
Not only a 'voluntary control system' "HAL" has, but also a 'robotic autonomous control system' that provides human-like movement based on a robotic system which integrally work together with the 'autonomous control system'.
"HAL" is the world's first cyborg-type robot controlled by this unique Hybrid System."
