A virtually unstoppable "snakebot" developed by a University of Michigan team that resembles a high-tech slinky as it climbs pipes and stairs, rolls over rough terrain and spans wide gaps to reach the other side.
The 26-pound robot developed at the University of Michigan U-M College of Engineering is, called OmniTread. It moves by rolling, log-style, or by lifting its head or tail, inchworm-like, and muscling itself forward. The robot's unique tread design prevents it from stalling on rough ground, said Research Professor Johann Borenstein, the head of the mobile robotics lab at U-M.
