  • This remote-controlled robot, with a nose-mounted camera,

  • turns right and left, moves up and down, and even flies

  • through a ring, all on command from a controller,

  • who uses a special instrument.

  • And what is this instrument?

  • The controller's mind.

  • Here at the University of Minnesota, professor Bin He

  • and his team have engineered a noninvasive system,

  • called a brain/computer interface, that allows a person

  • to control a robot using only their thoughts.

  • Dr. He's team includes Alex Doud and Karl LaFleur.

  • For example, if you imagine making a fist

  • with your right hand, it turns the robot to the right.

  • And if you imagine making a fist with both hands,

  • it moves the robot up.

  • Here's how it works.

  • When the controller imagines a movement,

  • without actually moving, specific neurons

  • in the brain's motor cortex produce electric currents.

  • These currents are detected by electrodes in an EEG cap,

  • which sends the signals to the computer.

  • The computer translates the signal pattern into a command

  • and beams it to the robot via WiFi.

  • In this case, "turn right."

  • This brain/computer interface technology is all

  • about helping people with a disability

  • or various neurodegenerative diseases-to help them regain

  • mobility, independence, and enhanced performance.

  • We envision they'll use this technology

  • to help control wheelchairs,

  • artificial limbs, or other devices.

  • This has tremendous potential for people

  • who can't move or speak.

  • And the best part is it's completely noninvasive.

  • Nobody has to have a chip implanted in their brain to pick

  • up the neuronal activity.

  • We are very proud to have taken this step toward that goal.
