Here is another rugged robot for search & rescue and inspection jobs. The Front Tilt Minibot has an all-aluminum shell and the ability to turn on a dime. It comes with a camera mount with LEDs, so you can capture clear images.
The robot has a low-profile design and can navigate under vehicles and inside pipes. It can handle up to 30-degree inclines. It weighs under 10 lbs and runs 1hr on battery.
