Robot Snake Can Climb Trees 90

kkleiner writes "The latest in a line of 'modsnakes' from Carnegie Mellon's Biorobotics Lab, Uncle Sam can move in a variety of different ways, including rolling, wiggling, and side-winding. It can also wrap itself around a pole and climb vertically, and even scale a tree. You have to watch this thing in action. There is something incredibly life-like and eerie about the way it scales the tree outdoors and then looks around with its camera 'eye.' Projects like Uncle Sam show how life-mimicking machines could revolutionize robotics in the near future."

    Other than not having limbs, this has little to do with a snake. This looks like a bunch of U-Joints with servo motors, its "rolling" up the tree, after "rolling" on the ground. A snake does not move this way.. No animal that I know of moves this way.

    It's also obviously being controlled.. The AI to find a tree then decide to climb it (motivation?) would be really interesting.

    This is neat, but I don't see anything to do with snakes here.. Which is a shame.. Many years ago for a Comp Sci project, I had to model a snake and it's movements (virtually -- it was an OpenGL assignment). It was really interesting to do, mimicking those thousands of coordinated muscles with electronics would be pretty fantastic. Of course, different snakes move differently .. a sidewinder basically walks on two virtual "feet", whereas a python crawls and climbs with hundreds of individual "feet".

    As far as I know, the only snakes that allow themselves to be on their back are either playing dead or actually dead. There's at least one species that will roll over and emit a "death odor" to fool predators, but with most snakes, even if they're almost dead, if you roll them on their back they go straight over again.

The cost of feathers has risen, even down is up!
