This mind-controlled robot could open a new world for people with disabilities.
And unlike its predecessors, this one doesn't require a brain implant.
Research subjects wear an electroencephalography (EEG) cap, which records brain activity and turns thoughts into movement.
Humans do the thinking, and the robot does the work.
Researchers say this technology could help people who are paralyzed or have limited motor function due to conditions like muscular dystrophy, stroke and spinal cord injuries.
