Max and I have started on the major components required for driving the vehicle. We will be mounting a potentiometer inside the steering wheel assembly, the APM board will use the resistance of the pot to determine the steering position, and control the steering servo appropriately.
The IR distance sensor is used to detect obstacles while driving autonomously (GPS waypoints etc). It will correct the steering to attempt to avoid the obstacle.
