Methane is a major contributor to global climate change, and roaming around garbage landfills to look for methane gas leaks is an incredibly dirty—and difficult—job for humans. So obviously you would want to employ a robot to do the task harder, faster, better, stronger.
Enter the Gasbot. It's a mobile methane-sniffing machine developed by researchers at Örebro University in Sweden, with funding through Robot Dalen. The GPS-equipped robot comes with a remote sensor that can detect methane without having to be right on top of a smelly gas leak. It does this by using two lasers to sniff the air for traces of methane gas.
