Colorado Teen Designs Robotic Arm With 3D Printing 68
coolnumbr12 writes "A Colorado teenager has used 3D printing to create a robotic prosthetic arm that is fully functional and costs less than $500 to make. At TedxMileHigh in Denver, Colo., 17-year-old Easton LaChappelle demonstrated his robotic arm, and how he constructed the arm to keep costs low. 'So in the end, I built this robotic arm up to the shoulder which was extremely strong,' LaChapelle said. 'It could toss balls to you, it could shake your hand, it could pretty much do anything a human could if you program it correctly.'"

There's the problem, making something that looks like a prosthetic arm is the easy part. Programming it to make it work, as well as ensuring that it is durable enough for an arm is the remaining 90% of the work he has to do.
