Let's Make Robots!

Wall following robot

Hey guys,

Just wondering if I'm on the right path. I have to make a robot tht stays a fixed distance from a wall. I'm thinking of using 2 ultrasonic sensors that would be mounted near the front and rear wheels. So the robot is parallel when the difference between sensor1 and sensor2 is zero.

So I guess use one sensor (say, in the front) to check the distance from wall and both sensors to align it to the wall (PID?). Huh... any tips, hints.
