BigDog, Quadruped Robot by Christian Eager
Robots
At the other end of the Uncanny Valley from Keepon is BigDog, developed by Boston Dynamics, with funding from DARPA.
It can best be described as a pack animal: about a meter in length, it walks at 4mph, climbs slopes up to 35°, and carries loads up to 340 pounds. Oh, and it's creepy as all get-out.
