Inside the mouse there are little wheels with slots in. They pass through a gap between an IR LED and a photodiode, so the movement of the mouse ball can be sensed. Take the LED and photodiode out of the mouse and mount them on the front of the 'bot. Arrange them at an angle, and when the bot gets close to a wall, the IR will reflect off the wall and be detected by the photodiode. You will need a constant power supply to both components, and when the photodiode detects the reflected IR, it will allow current to pass, which can be used to control your chosen avoidance mechanism.
