Two Mind-Controlled Robot Arms video. Robot arm grabs objects via thought control. The science of thought control has developed a stage further, thanks to scientists at the University of Pittsburgh. An American quadriplegic was able to grab a series of objects using a robotic arm in a laboratory after two small electrode grids implanted in her brain were connected to a computer. Research biomedical engineer Jennifer Collinger developed the system which uses the two quarter-inch grids implanted in the brain of 55-year-old Jan Scheuermann, in the region of the left motor cortex responsible for controlling her right arm and hand. Each electrode has 96 contact points, allowing her brain activity to be analysed by the connecting computer. Algorithms learned to match the electrical patterns in Scheuermann's brains to her thoughts about making specific hand or arm movements, allowing her to pick up objects such as cubes and balls simply by thinking about them. Scheuermann became paralysed from the neck down in 2003 due to a neurodegenerative condition. The Pittsburgh resident has taken part in experiments for the past two years. A previous model of the hand was used to allow Scheuermann to give high-fives to researchers, and feed herself chocolate. The new model allows the hand to scoop, pinch, and give the thumbs-up sign. The results were published in the Journal of Neural Engineering. Thanks for comment, subscribe to updates http://goo.gl/8faygM and More news follow Twitter @newsdailyplanet
