From Ping-Pong table to Harvard: This 13-year-old built a Rs 3,000 robotic arm you can control with mind

A teenager Benjamin Choi built a low-cost prosthetic arm during the 2020 lockdown using a 3D printer, fishing line and non-invasive brainwave technology. After more than 75 prototypes, his AI-powered arm could interpret brain signals with about 95% accuracy and cost around $300 (nearly Rs 3,000) to manufacture. The project earned him major science and engineering recognition and led to research opportunities at MIT, Johns Hopkins, NASA and Harvard.
