Welcome to my Engineering Portfolio!

Hello there, I’mMaxwell NakatsujiMechanical & Biomedical Engineer from Tufts University

I’m a mechanical engineering master’s student with a biomedical engineering degree from Tufts. I design and build medical devices, robotic mechanisms, and biomedical systems—with hands-on experience in prototyping, research, and quality engineering.

Available for internships, co-ops, and full time positions!

EMG & Vision-Controlled Prosthetic Hand

We developed a prosthetic-hand prototype with affordability as a design goal, using EMG-voltage changes for opening and closing and MediaPipe tracking for individual finger movement. MG90S servos, fishing-line tendons, and elastic finger return combine with an iteratively refined palm and thumb geometry for ball grasping.
