Bizarre galloping robot joins US military - video
Meet Wildcat, the uncanny military mechanoid that looks like a giant flea and runs like a dog
What's got four legs, a two-stroke engine and can chase you at 15mph? The answer is Wildcat, a robot developed by the US Military.
The robot, which has the engine from a go-kart, is designed for terrain where wheels would prove a disadvantage - although its first test, shown in the video above, was conducted in a Massachusetts car park.
Wildcat was funded by the Defence Advanced Research Projects Agency and built by engineering firm Boston Dynamics. A year ago, the company showed off the Cheetah, a similar robot that could run at 30mph while tethered to a treadmill.
