Mind-controlled robot allows a quadriplegic patient moving virtually in space
Researchers at Federal Institute of Technology in Lausanne, Switzerland (EPFL), have successfully demonstrated a robot controlled by the mind of a partially quadriplegic patient in a hospital 62 miles away. The EPFL brain-computer interface system does not require invasive neural implants in the brain, since it is based on a special EEG cap fitted with electrodes that record the patient’s neural signals. The task of the patient is to imagine moving his paralyzed fingers, and this input is than translated by the BCI system into command for the robot.
