Hybrid Assistive Limb

The HAL-5 exoskeleton robotics suit by Tokyo-based company Cyberdyne, is a wearable device that helps ordinary people accomplish extraordinary feats, such as lifting objects they otherwise couldn't. a sensor attached to the skin, "HAL" captures faint biosignals on the skin's surface that result from messages sent from the brain to muscles when a person attempts to move. A computer analyzes how much power the wearer intends to generate, then calculates the amount of torque needed to put limbs into action.
