Autonomous Vehicle Platform Background The goal of this

Autonomous Vehicle Platform Background The goal of this project was to create a new platform to build and assemble a remote car that can autonomously navigate a track. The previous NXP Cup car design was used as a reference to develop a working car model so that students in the Interface Digital Electronics (IDE) can learn how to interface and program a small car to autonomously navigate the track.
