Mind Controlled Drones


Professor Bin He
University of Minnesota

In the lab of biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring. The technology, pioneered by He, may someday allow people robbed of speech and mobility by neurodegenerative diseases to regain function by controlling artificial limbs, wheelchairs, or other devices. And it’s completely noninvasive: Brain waves (EEG) are picked up by the electrodes of an EEG cap on the scalp, not a chip implanted in the brain. Monitoring electrical activity from the brain, the 64 scalp electrodes of the EEG cap report the signals (or lack of signals) they detect to a computer, which translates the pattern into an electronic command. Volunteers first learned to use thoughts to control the 1-D movement of a cursor on a screen, then 2-D cursor movements and 3-D control of a virtual helicopter. He’s computers interface with the WiFi controls that come with the robot; after translating EEG brain signals into a command, the computer sends the command to the robot by WiFi.
