Fitness OS

Fitness OS: a standalone, AI-powered posture and rep coach for squats, built on the Arduino UNO Q. A USB webcam feeds a MoveNet pose-estimation model (TFLite) running entirely on the board's Linux side (Qualcomm QRB) — requiring no laptop, cloud, or phone app. Python code computes knee angle and torso lean from the detected pose and drives a squat state machine that only counts correct reps.

Inside the build

Team Naman

What they built: Fitness OS: a standalone, AI-powered posture and rep coach for squats, built on the Arduino UNO Q. A USB webcam feeds a MoveNet pose-estimation model (TFLite) running entirely on the board's Linux side (Qualcomm QRB) — requiring no laptop, cloud, or phone app. Python code computes knee angle and torso lean from the detected pose and drives a squat state machine that only counts correct reps.

What it solves: Home exercise done wrong is worse than not done at all; people cheat depth, round their backs, and count bad reps, with nobody watching. Fitness OS enforces correct form in real time: it only counts reps done right, and buzzes the instant form breaks.

This is for rehab and physio patients doing prescribed exercises at home unsupervised — plus anyone training solo who wants an honest rep count without a coach, laptop, or app. (An offline AI coach that counts only your correct squats, a physio's rules, enforced 24/7 on a board).
