This week’s attention-getting version of a mind-controlled robotic device comes in the form of an Emotiv EPOC BCI headset controlling a robotic arm with a system smart enough to move the arm using simple movements such as a clenched jaw or wink of the eye. University of Toronto student Ryan Mintz and his team connected an Emotiv EPOC BCI headset to a robotic arm, which responded to the brainwaves captured by the headset. Emotiv EPOC is a high resolution, multi-channel, wireless neuroheadset. The EPOC uses a set of 14 sensors and two references to tune into electric signals produced by the brain to detect a user’s thoughts, feelings and expressions in realtime. The EPOC connects wirelessly to most computers. The team designed the system with the hope of contributing to technologies applied to prosthetic limbs.
