Overall Description

Capture.PNG

The battery will power the motors,  voltage converter, raspberry pi, arduino mega, and the electronic speed controller (ESC).

 

The raspberry pi will be used to communicate  with the Comprehensive Open-Architecture Solution for Mission Operations System (COSMOS).  The arduino mega will be used to communicate with the ground station.

 

This configuration is based off a rear wheel drive, where the front wheels is steered using a small DC motor and the back wheels is powered by 2 DC motors controlled from the ESC.
