Nilay Mehta, a 17-year-old high school junior at California's Irvine High School, has created an incredible that has now taken home awards in several California-area science fairs. Struck by the high prices (some over $35K) of advanced prosthetic limbs, Mehta set out to create a high-functioning, low-cost limb. Through a combination of motors and 3D printed parts, he succeeded in producing a robotic, voice-operated arm for just $260. The arm can grasp, pinch, point, and perform other precise tasks, all at a voice command. The hand was designed with help from UCD orthopedic professor Gavin Periera, and printed on the Long Beach Public Library's 3D printers, and uses an Arduino board and servo motors to run.
