Homemade Arduino-based vacuum cleaner robot project.

This video is about testing ultrasonic sensors. 4 sensors total, but only the front ones working at the moment. The sensing distance is set to 20cm. The green thing on the top is the vacuum system. The dust container and the nozzle isn’t mounted on now, but may be seen on the earlier video. The ultrasonic sensors are these from dealextreme: Check out a short video how this ugly duckling got some cover on after a year from this vide
