Boston Dynamics keeps refining its Legged Squad Support System, the robotic quadruped descendant of the good old and creepy Big Dog. The new version of the eerie mechanical horse, which will aid US Marines squads once finished, got some cool upgrades.

Now it is smart enough to follow the squad lead, which is quite important. This thing doesn't need to be remote controlled. It's smart enough to go along its human masters. Apparently, it's also intelligent enough to follow paths and work in tandem with his robotic brothers.

Also, for some reason watching him go out of the bushes seems to me funny as hell. Although I can imagine being the enemy and seeing this thing popping out of a forest. That will not be quite as funny.

It also seems more silent than its predecessor, although perhaps that's just the video audio level.

Unlike cars or trucks, the robo-horse can travel through any rough terrain, and will carry 400 pounds of payload and travel 20 miles without refueling. It will carry more than one hundred pounds of cargo per Marine in the squad.
