The HAL (Hybrid Assistive Limb is a powered exoskeleton suit developed by Japan’s Tsukuba University and the robotics company CYBERDYNE. When a person attempts to move their body, nerve signals are sent from the brain to the muscles through the motor neurons, moving the musculoskeletal system. When this happens, small biosignals can be detected on the surface of the skin. The HAL suit registers these signals through a sensor attached to the skin of the wearer. Based on the signals obtained, the power unit moves the joint to support and amplify the wearer’s motion. Continue reading for more.
