Do you remember what you did during quarantine? Cui, a 17-year-old high school student in the United States, built a thought-controllable low-cost robotic arm using a 3D printer, using the extra time during quarantine.
He devoted his free time to this project
During the COVID-19 pandemic, people had to stay at home. Benjamin Choi, a 17-year-old high school student living in the US state of Virginia, was also at home, but he did not stay idle and pondered on this project. During the epidemic, he built a robotic arm that can be controlled by the mind under his own power. The finished product is extremely complete and has taken many experts by surprise.
Inspired by documentaries
When Cui was 8 years old, he was watching documentaries introducing new technologies and was always curious about these issues. Cui borrowed his sister’s $75 and a 3D printer to personally design the shape of the robotic arm and prepare it for printing.
However, it ran into a problem while printing, this 3D printer could only print 12 cm long objects at a time. To circumvent this problem, he had to change his construction method, breaking the arm into several parts and printing them all, then using screws and wires to assemble the parts. It took about 30 hours for Cui to assemble the 3D printed arm.
