SMART-PAD
SMART-PAD is a real-time player localization and motion analysis system designed for volleyball. Using five ESP32 UWB sensors, I built a 4-layer IoT pipeline that streams live position data over WebSockets and applies Python + NumPy trilateration to calculate player movement and advanced metrics like jerk (rate of acceleration change). The data flows into a Nuxt.js/Vue.js/D3.js dashboard that visualizes player trajectories and performance metrics with sub-500ms latency, giving coaches and athletes immediate feedback on movement efficiency and positioning.
