Jet Propulsion Laboratory
The Open Source Rover is designed almost entirely out of consumer off the shelf (COTS) parts.
This project is intended to be a teaching and learning experience for those who want to get involved in mechanical engineering, software, electronics, or robotics.
The electrical subsystem consists of the motors, motor controllers, brain, LED array for the face, battery, and other electronic components that will control the rover. See the project's main roadmap for information on when you should be building your electrical subsystem. The electrical subsystem needs to carry two major things throughout the rover: power and data.
Below is a high-level diagram showing how power is transferred around the rover
