(Video) Carnegie Mellon's Robotic Snake
A unique robot uses biomimetic movements that allow it to climb trees and travel across difficult terrain.
The Biorobotics Laboratory at Carnegie Mellon University has been developing a unique type of robot that mimics the movements of snakes. The latest version is named “Uncle Sam,” and is capable of travelling across difficult terrain a bipedal robot would find difficult or impossible to navigate.
The snake’s movements are biomimetic, mimicking movements of real snakes including side-winding, wiggling and rolling. Now the snake robot can also wrap itself around a tree trunk and climb vertically up the outside of the tree. An earlier version has previously been demonstrated climbing vertically inside pipes. The many internal degrees of freedom make the snake robots extremely flexible and maneuverable.
