The "dog bots" from Boston Dynamics are just amazing pieces of hardware—its "BIGDOG" pack robot is eerie to watch, nimble and resilient—and the LittleDog platform, while seeming more insectoid than canine, still somehow slips up around either edge of the uncanny valley. Its motion is more lifelike than most bots, but unlike a humanoid robot it still looks like it has a firey clockwork soul in there somewhere. And unlike the BIGDOG, which looks like the lower half of a dog knitted into a steel framework and fueled by sloshing ichor, the LittleDog looks more like a tentative crab.
Actually, that's exactly what LittleDog reminds me of: a mechanized version of the headcrab from Half-Life, albeit with an extra set of legs. And less face eating. For now.
