Past Work

Prosthetic Arm R&D

Low-cost myoelectric transradial prosthesis — sEMG control, tendon-driven mechanics, SolidWorks drawing package.

• Sub-$500 prototype target ($350–$500) vs. $20,000–$80,000 clinical myoelectric devices.
• <500 g assembly mass; 10–15 N grip force for activities of daily living.
• ≤100 ms sEMG system latency — brachioradialis and flexor muscle groups.
• 19-part tendon-driven hand; 12 kg·cm servos over 2.52 kg·cm torque target.
• 6 subteams: mechanical, electrical, software, ergonomics, physiological, safety.
• 6-sheet SolidWorks package — prototype assembly, housing, bracket, and finger phalanx details.
