Ok, did anyone else ever read Arthur C. Clarke's sci-fi novel, Rendezvous with Rama? The connection here is a little thin, but I had a distinctive flashback when I saw it. In Clarke's story, astronauts land on a visiting spaceship, initially thought to be dead, but which later turned out to be the home of all sorts of robots.
Everything on Rama reflects a theme of "three", including one type of robot that Clarke describes in great detail. This spider-robot is said to look like a three-legged daddy longlegs, and the way it moved sounded pretty far-fetched, at least until I saw this robot from Virginia Tech. I'm sure this won't turn out to be the most practical form of locomotion, but it's a wonderful example of thinking outside the box. (read more about it on Engadget)
Really cool, but thats notReally cool, but thats not how the thing in Rendezvous with Rama moved (it wasn’t even a robot). The tripod spider thing moved by kinda spinning around on an angle to use its three legs like a large wheel
really cool though
