OmniTread: A serpentine robot
karvind writes "Physorg is running a story about OmniTread: a serpentine robot designed to traverse extremely difficult terrain, such as the rubble of a collapsed building. The 26-pound robot is developed at the University of Michigan U-M College of Engineering. It moves by rolling, log-style, or by lifting its head or tail, inchworm-like, and muscling itself forward. Link to videos. Check out there other robots as well."
Their other robots are there. They're amazing.
This is more like a caterpillar than a snake. It uses tracks all over its body (like many small feet), rather than a serpentine motion to propel itself. Props though, as this seems far more practical than robots that actually try to move like snakes or inchworms.
I've sat through many talks about modular robots that are supposed to be able to do everything, yet rarely do anything well at all (I come from a lab doing what I guess you'd call "specialized monolithic" robots). I think this robot is just specialized enough to be useful (using its treads). The walking snake like robots are normally agonizingly slow, but this robot moves at a reasonable speed for the type of applications you'd need it for. Also, tracks should scale up in speed reasonably well if needed.
