Story

During this project, we tried to make a car as efficient as possible for the NXPCUP. This project is part of our schooling at Polytech Montpellier.

We chose to participate in the NXPCUP, because this project interested us a lot, the competition aspect was motivating and working on an autonomous car is super cool


At the beginning, we were interested in the rules of the competition, in order to know what was possible to do. Then we thought about the direction algorithms we were going to use.

We tested our algorithms on Matlab and implemented them.

Then we made improvements, then we were blocked by the mechanical aspect of the car, so we improved the car.

At the end of the project, once we chose not to change any more parts on the car, we improved the code by adding new ideas.
