Gym Performance Evaluation Device Naprava za oceno vadbene zmogljivosti

Overview Pregled

Compact embedded device for measuring force and motion on gym cable machines. Uses strain-gauge load cell and 6-axis IMU to classify movement phases in real time. Kompaktna vgrajena naprava za merjenje sile in gibanja na fitnes napravah s kabli. Uporablja merilno celico s tenzometrom in 6-osni IMU senzor za razvrščanje faz gibanja v realnem času.

Streams data over BLE to a React Native + TypeScript mobile app for live visualization, automatic phase detection, and training analysis. Pošilja podatke prek BLE v mobilno aplikacijo React Native + TypeScript za vizualizacijo v živo, samodejno prepoznavo faz in analizo vadbe.
