Sports Agnostic Measurement Platform Team 3: Tony Cartolano Koushik Sampath Greg Slovin Nik White
Motivation • What really happens when sport objects are thrown/hit/caught? • What control attributes affect accuracy, distance? • How can object data be repeatedly captured, analyzed, and turned into useful feedback to players? • MEMS will provide the answer • New accelerometers and gyroscopes are small and tough enough to embed into sports equipment and measure event characteristics • Coupled with the right processor, software, and communication hardware, an unprecedented platform for data analysis emerges
Competitive Analysis • Very new area, only niche products • RevFire Baseball/Softball • Measures RPM and pitch speed • RF communication with handheld display unit • Expensive, single-use battery, cannot withstand shock • Flying Tach Frisbee • Measures RPM and flight time • On-board display • No agnostic platform capable of multi-axis capture and analysis
Requirements • Multi-axis data capture • Small, low-power design • Fit in almost any sport object • Last for majority of period/quarter/inning/half • High Shock Tolerance • Simple UI • Reliable data capture, logging, and communication • Wireless power and communication are highly desired
Hardware! • Processor • Arduino Pro Mini 328 • MEMS Sensors • Invensense IDG-500 Dual-Axis Gyro • Analog Devices ADXL-345 Tri-Axis Accelerometer • Memory • MicroSD for up to 2GB storage • Easy transfer to personal computer for offline analysis • Battery • LiPoly for small size, high power density • Inductive charging?
Future Directions • Profile sports to determine minimum data required -> less/cheaper parts, code efficiency, introduce real-time analysis & feedback • Create our own custom integrated PCB • Smaller size, lower weight • Lower cost, sports-specific solutions? • Truly wireless operation • “Dock” with inductive charging and short-range RF communication for data transfer • Enables seamless embedding into sports objects
