Mars Exploration Rover

We're making a near-replica of the Mars Exploration Rover. For basic functionality, the robot will be able to traverse bumpy terrain with ease. The wheel system will allow it to travel over tiny obstacles as well as over small dips. The robot's intentions will be to pathfind in a direction specified by IR signals. It will use a sonar sensor to find obstacles larger than it can traverse over and avoid them. In the "wall" scenario, the robot will turn around to its last traversal and try a different safe path. Our robot will also have a mechanical arm to read rock data from the terrain and record it. Data requests will be queried by IR signals once again and the robot will feign the actions of sending its information. The intricate motor turns can only be regulated by the very necessary rotation sensors, and in order to fit all 4 motors onto the brick, it is imperative that we combine the turning system with the sonar sensor base.
