Benjamin Choi, 13, created robotic arm using $75 3-D printer
Benjamin Choi, just 13, created a robotic arm in 2020 using a $75 3-D printer, fishing line, and brainwave technology.
Inspired by a TV segment on a paralyzed patient who could move a robotic arm using only her thoughts, thanks to sensors surgically implanted in her brain, he wanted to make something safer and way more affordable for people who need it.
Choi's prosthetic uses AI and EEG
His prosthetic arm uses AI and EEG sensors to read brain signals and turn them into movement; pretty amazing for something that costs only $300.
That's a huge drop from traditional prosthetics, which can cost thousands.
With 95% accuracy and over 75 design tweaks, Benjamin's work is changing the game.
Benjamin Choi now Harvard AI researcher
Benjamin's invention has earned him awards and opportunities at places like MIT, NASA, and Johns Hopkins.
Now an AI researcher at Harvard's Kempner Institute, he keeps improving his device while studying applied math and computer science.
