RoboGat is a robotic fire-fighter for tunnels. The aim is to prevent disasters like the fire in the Mont Blanc tunnel between France and Italy that killed 39 people. The robot will travel along the top of the tunnel and shoot a stream of water at the hottest part of the fire. Of course, this doesn’t solve the ventilation problem of having the fire suck out all the oxygen from the tunnel. But, it’s still a good idea.
