After meeting a young girl with a prosthetic arm and realizing that it costs $80,000, 17-year-old Easton LaChappelle decided to break away from the limitations of the public education system and taught himself electronics, coding, 3-D printing etc to create a low-cost 3D printed prosthetic arm and hand that is connected to the brain. The system uses a wireless brain EEG headset that picks up 10 different channels of the brain to move the arm. Unlike some of the more advanced options that are currently on the market, amputees don’t need a risky surgery to use this prosthetic arm, it’s something that can be taken on and off. And the best thing is that it is affordable and accessible by far more amputees with its price less than $400. The technology is so useful that NASA hired LaChappelle to work on the Robonaut, a robot to be sent to the space together with astronauts. It mocks human movements to perform maintenance tasks and duties that are too dangerous for astronauts in space.
