University of Illinois Urbana-Champaign researchers have developed a mind-controlled robot that can weld metal together after receiving mental instructions from its operator.
The operator controlling the robot wears an electroencephalography (EEG) cap, which measures the brain's electrical activity; the operator then looks at a screen with several pre-selected metal seams for the robot to weld.
Each option on the screen flickers in turn and the user stares at a specific one, the selected option flickers, generating an electrical response in the brain that is detectable by the cap.
The robot matches the electrical responses to the timing of the options displayed, identifying where the user was looking and which welding seam has been selected.
If the robot correctly confirms the selection, the user pushes a button to start the robot welding.
