About the project
An autonomous vehicle in scale 1:18 powered by two independent electric engines and steering by using servo. Our car is adapt to race in EMEA NXP CUP competition. The goal is use a PIXI CAM 2 camera to give our car eyes and to write perfect algorithm to be the fastest.

Story
About the project
The project contains multiple hardware, software and mechanical elements, combined together in order to create an autonomous car, capable to move on the track without any human control. Vehicle is programmed to move on the track and support some features defined by the NXP Cup competition rules.
The project is maintained using the Git repository system. Navigate to the following location to find our embedded firmware and software libraries, as well as hardware platform and mechanical parts designs.Story
Mechanical platform
As expected, the vehicle needs to have a chassis that will ensure a stable fixation of all components. There are several chassis models recommended by the NXP Cup competition organizers and the Landzo Alamak chassis is the one selected for this project.
The Alamak set contains chassis, servo steering system and motors, but the last two elements were replaced in order to reduce response time of the steering system, provide better durability and allow car to reach higher velocity.
There are also plenty of elements that were created using 3D printing technology in order to enhance the car chassis by adding holders, stabilizers and reinforcement elements.
The steering system
System consists of a few elements, which goal is to fix servo to the chassis and allow turning the wheels by moving swingarms. Additionally, the servo holder is combined with the camera mast holder and the microcontroller board holder, what provides durable and stable fastening of all elements. The 3D models and photos were presented below:
