BDI just released a new video of the Big Dog on ice and snow, and also demoing its walking gait.
Boston Dynamics keeps working on their BigDog quadruped robot, which will probably grow to be the future AT-AT of the Pentagon. Its evolution since the last time we saw it is nothing sort of mindblowing, and a bit spooky.
It looks like an actual biological quadruped. Seeing it climb through rubble, snow, jumping over obstacles like a wild goat, and saving a near-fall on iced ground at the last second (fast forward to the middle of the video) defies belief. It feels so "animal" that I almost feel bad when they hit it to demonstrate how it regains balance on its own.
The new version of the robot can now carry 340 pounds, which is almost triple the previous weight. It looks to me that that $10 million funding they got from Darpa has been put to good use. [IEEE]
