Next Generation Implementation of an Improved Telemetry System for Monitoring an Off-Road Racecar

Abstract

The University of Arizona Baja Wildcat Racing Team designs and fabricates an off-road vehicle for an international competition. A telemetry system serves as an important backbone for design optimization and problem detection. The system consists of an array of sensors, microcontrollers to read them, and the core module. The core module is the heart of the system and it compiles, transmits, and stores the data locally. A custom screen displays speed data to the driver. The software saw a total redesign. The primary changes were the implementation of a data management class to improve I2C communications, and the generation of data structures using python scripts to reduce the risk of data loss. The software will be the primary focus, with detailed design justification, and hardware updates will also be discussed.
