“Robots are a step closer to reading our thoughts, thanks to researchers at the University of Minnesota. Biomedical engineers in the U’s College of Science and Engineering have developed a non-invasive system that allows people to control flying robots using only their minds.
The engineers created a skullcap fitted with 64 electrodes that can track the electrical activity of a subject’s brain. The brain signals were sent to a computer, which translated them into Wi-Fi commands to a four-blade flying robot.”
