The Braitenberg vehicle[9] using ultrasonic sensors bumps into several objects on it's way. It bumps into walls twice (including a wall-like, laying chair) at an angle and drives into a chair leg. We have discovered both of these situations in previous exercises. Chair legs are very difficult to detect, and when the ultrasonic sensor points towards a wall at to large an angle, the sound is not reflected back to the sensor, but away from it.

We built the Braitenberg vehicle 3 using two ultrasonic sensors and two light sensors. The light sensors had the floodlight disabled. Our goal was to create a robot avoiding obstacles and shadows.
