Range sensors do exist. So, you could measure the distance from the wall and have the robot stop at the same distance each time. If you have a radio shack near by they sell VEX Ultrasonic Range Sensors which do this. There are also IR range finders as well.

Could you please tell me more about this? What exactly will VEX Ultrasonic Range Sensors do? How will they tell me where a hole in the wall is located? That is, what values do these sensors typically return? And does FIRST definitely allow these and other off-kit electronics? Also, what are infrared range finders? What kind of values will these return? I really know nothing about sensors. Lastly, what price ranges are all of these components in? Are we looking at something extremely pricey?
