Are you smarter than a high schooler? I bet you are not smarter than Benjamin Choi, a high school student who invented a low-cost, mind-controlled prosthetic arm.
Creating things like this must really spark joy in Benjamin Choi. He went from participating in robot-building competitions when he was younger to eventually teaching himself coding and computer programming.
Choi’s device was inspired by a documentary he saw that discussed mind-controlled prosthesis. He turned this fascination with prosthetics into something that is real and functional. He worked around 16 hours daily in his basement, where he designed the robotic arm using a 3D printer. Although he did not have the best laboratory or the best printer in the market, this did not stop Choi's resourcefulness.
Now, the robotic arm is made from engineering-grade materials and has a total unit cost of only around $300.The arm is operated using an algorithm driven by artificial intelligence. The promising features of the invention earned him a spot in the top 40 finalists of Regeneron Science Talent Search 2022.
