Precision Motion and Resistance Cube (PMARC)

An adjustable strengthening device and bio-mechanical dynamometer designed for in-orbit astronaut resistance training aboard NASA Artemis, with direct application in clinical hand and wrist rehabilitation. Currently licensed to an overseas partner for commercial therapeutic use.

Built for the realities of long-duration space travel, where months in microgravity compound into significant muscle and bone loss, PMARC reimagines how we exercise by making strength training compact, measurable, and engaging enough to sustain across an entire mission. An embedded electronic module captures force, repetition, and range-of-motion data in real time and syncs to a companion app that visualizes progress, gamifies sessions, and helps users actually keep showing up.
