HARDWARE-SOFTWARE CO-DESIGN OF INTEGRATIVE TELEMETRY SYSTEM FOR OFF-ROAD RACING VEHICLE

Abstract

The University of Arizona Baja Wildcat Racing Team’s integrative off-road telemetry system merges custom circuit boards and a C#-based, GPU-accelerated GUI. Utilizing CAN-bus, I2C, and SPI protocols alongside NRF24L01 devices for wireless communication, it collected data via IMUs, temperature sensing devices, three speed sensors, an induction-based tachometer using spark plug-driven input, and pressure transducers. The system monitored RPMs, positional data, and brake actuation, enhancing real-time data visualization through an improved dashboard interface. Hardware and software advancements significantly refined telemetry accuracy and driving insights, optimizing vehicle performance. This innovation demonstrates a leap forward in the university’s off-road racing telemetry.
