If you’ve ever lived or stayed in an area with a limited Internet connection or a 3G dead zone, you’ll know exactly how frustrating it can be even to just quickly check your emails. Perhaps people living in such areas should invest in something like the Wi-Fi Extending Robot.

This tank-like machine by students at Northeastern University will locate Wi-Fi in hazardous areas where there might not be much of a network infrastructure. It is operated remotely, and features an Eee PC (running Linux, Arduino, and Node.js) on board to act as the tank’s main brain.
