These Mind-Controlled Robots Are Changing Paralyzed Patients' Lives
Mind-controlled robots have helped paralyzed patients regain some control over parts of their bodies.By Evan Thomas | August 11, 2016
For decades, scientists have tried to build machines that can scan a person's brain and translate their thoughts into movement. The research has had some success, offering rare hope that paralyzed people or amputees might one day be able to move and walk again just by thinking.
But researchers in Brazil and the U.S. weren't expecting to see their test subjects actually get better. In an incredible first, people who were completely paralyzed regained some natural control over their own bodies — all by training to work with robots.
Eight paraplegic patients spent a year using brain-scanning helmets to move virtual legs or command robotic body parts as part of the Walk Again Project.
