Last year, DARPA unveiled Cheetah: a robot that could run faster than Usain Bolt. Now, the same team has managed to create a version that doesn’t need a power cord, making the electronic beast free to roam wherever it chooses. Be afraid. Be very afraid.
A relative of Cheetah, say hello to WildCat. This robot is based on the same design as Cheetah, but doesn’t have the tethered power cable of its predecessor; instead, it has a large — and quite loud! — motor attached to it.
That extra weight does means it can’t quite match the pace — Cheetah can reach 45km/h, while WildCat can only manage 25km/h. But, hey, given that’s faster than most of us can run, it’s not too bad. And remember, WildCat can keep up that speed for as long as it motor runs, which humans definitely can’t.
