world domination posturing by robots, you wouldn't think they'd be so dang good all this humanitarian and safety-related stuff, but it seems if they aren't busy pulling somebody out of a building, they're inspecting those very buildings for structural integrity. These new bots by the University of Strathclyde fall into that latter category, and use bat-inspired echolocation to navigate and inspect their surroundings. The robots report back to a mission control computer which manages the group of robo-inspectors based on the collective findings. There's also a camera on board each bot, along with a magnet to test for corrosion. It doesn't look like these bots will make it to market for another 10 years, but when they do they're expected to make the job of inspecting nuclear installations and gas pipelines a whole lot more fun.
