Kelpos Robotics: Improving Sustainability, Cost, Modularity, and Accessibility for Prosthetics

Overview

Kelpos Robotics addresses the global prosthetic crisis, where high costs limit access to only 3% of low-income individuals, by engineering a modular, sustainable, and theoretically affordable myoelectric prototype. This research utilizes marine biomass-derived bioplastics synthesized through alkaline ion exchange and calcium acetate cross-linking to create a non-toxic, biodegradable prosthetic. Through four iterative design cycles, we resolved critical subsystem failures by implementing a 6-volt split rail power architecture to stabilize high torque servo actuation. The final MK III-FX architecture features a modular electronics tray inspired by professional marine robotics, significantly improving serviceability and scalability. Testing verified a cohesive polymer matrix and consistent electromechanical response within a 1/2 scale model. This project demonstrates a viable pathway for marrying material science with adaptive robotics to reduce the financial and ecological impact of assistive medical technology.
