[Andrew] sent in this sweet snake robot video. The snake bots are all about 36 inches long and built from lots of hitech servos and 6061 aluminum. The guys/gals at Carnegie Mellon have built quite a few of these, and I’d say that their work is paying off. They haven’t published much in the way of details, but it appears that the snakes are being computer controlled for faster behavioral development than an on-board mictrocontroller would allow. When I saw the snake motion I was reminded of the winner of the latest Tresser robotics contest – Phoenix. It’s a spider like bot based on servos, but with some very impressive motion programming that was designed with an excel spreadsheet.
