Here's a robot that at first I said "that thing is ugly" but after I saw it do what it is designed to do, I changed my mind. It is in fact one of the more beautiful designs I have ever seen. This robot uses several linkages to climb over some rather large obstacles very gracefully. It's from a demonstration in Japan. It's built by Taylor Veltrop, more well known for his work with humanoid robotics, but he also dabbles in Lego.
