That black box is hiding all kinds of goodies that make this rover a hacking playground. [Andrey] built the device around a BeagleBoard, which offers the processing power and modules that he needed to make the rest of it work.
The control unit shrinks the pilot down to the rover’s size, using a cockpit that has a steering wheel and other controls, and a monitor playing the stream from the camera on the front of the bot. It has a WiFi adapter which allows control via the Internet. The camera, which can be rotated thanks to its servo mounting, feeds the video to the BeagleBoard where it is compressed using the h264 codec (more about that and the cockpit here) to lighten the streaming load. You’ll also find an ultrasonic rangefinder on the front for obstacle avoidance, and a magnetic compass for orientation information. Finally, a GPS bolsters that data, allowing you to plot your adventures on the map.
It’s great, but it will cost you. Material estimates are North of five hundred Euros!
