2D Echolocator / Ultrasonic Position Following Robot

In this video I show my ultrasonic position following robot in action. As the name says it, It can follow the position of a near object. It works with 3 ultrasonic range finders, 3 servomotors and 1 arduino. It's probably the simpler and cheaper vision system anybody can make, and moreover, it's fully autonomous as all the computations are made in real time by the arduino.
