In hospitals and nursing homes in Japan, disabled people are learning to walk again by wearing a robot suit. The suit ironically named HAL, for the Hybrid Assistive Limb, is strapped to one or both legs to help the patient regain mobility.
I say ironically because HAL is the Artificial Intelligence villain of science fiction. But the exoskeleton HAL is in fact far friendlier. It has been designed to support and expand the physical capabilities of its users, particularly people with physical disabilities.
