Arduino, 3D Printing & Clever Engineering Result In An Affordable Prosthesis
After meeting a young girl who who wore an $80,000 prosthetic arm, Easton LaChappelle was convinced he could do better. Since then, he has made a series of continuously improving robotic hands incorporating various tech, including Arduino and 3D printing. The first DIY prosthetic hand, which he made at age 14, won 3rd place at the Colorado State Science Fair. And the second, which we previously covered, won 2nd place at the Intel International Science and Engineering Fair, the top science fair in the USA.
Now 17, Easton has completed the third version of his robotic hand. The prosthetic hand is primarily made with 3D printing, with the exception of motors, gears and other hardware. The control system is activated by flexing a pre-chosen muscle, such as curling your toes, then the movement is chosen and controlled by a series of eyeblinks and an EEG headset to measure brainwaves. The most remarkable part is that the hand costs a mere $250.
