The Hybrid Assistive Limb (HAL), created by Cyberdyne Corporation to “upgrade existing physical capabilities of the human body”, weigths 23 kg and is comprised of robotic limbs and a backpack containing the suit’s battery and computer system.
The HAL suit identifies nerve signals from/to the brain using a sensor attached the wearer’s skin and a signal is sent to the suit’s power unit telling the suit to move in unison with the wearer’s own limbs.
