Project Title

TEAM ZERO

Abstract

Team Zero's Self driving RC car, as the name states, is an autonomous vehicle designed to navigate to a given specified destination successfully, avoiding obstacles along its way. The car's infrastructure is built upon four key components: the Driver, Sensor and Bridge, Geo, and Motor nodes, which communicate internally via a CAN Bus and with the user via a mobile app. The vehicle continuously senses and processes all the information from these nodes to make decisions to ensure it stays on course and reaches its destination. It is built on a hobby-grade RC car chassis, modified with the necessary components and adjustments to fulfill its primary objectives of autonomous navigation and obstacle avoidance.
