Robot 3 was a radical design change from robot 2, I built the same thing but vertically and used a 3rd servo to rotate the ultrasonic sensor. This was also the first time I used a piezo crystal to generate tones which the robot used often whenever it was operating. The frequency of the beeps corresponds to the distance measurement from the ultrasonic sensor. I also have my sister to thank for drawing the mustache and the monocle on him, robot 3 is also known as Mr. Pringles.
