If you get creeped out by spiders, spindly legged-things or the thought that the Terminator movies could actually happen, look away now.

Boston Dynamics, creator of BigDog, has built a smaller, weirder version of its robot canine, which has a number of improvements to make it walk in a more life-like fashion. And, seemingly, climb over obstacles.

However, while clearly geniuses, the boffins have omitted the one part that would've made it easier to watch LittleDog's exploits without inducing nightmares and panic fits; a head!

There goes years of therapy. Thanks Boston Dynamics.
