Olin College Sidewinder - Rectilinear Gait

This is footage of the Olin College Sidewinder, the last phase of a year-long robotic snake development project that took place from fall 2005 to spring 2006.

In this clip the robot is demonstrating an exaggerated rectilinear gait, used by snakes to sneak up on prey slowly and silently. A vertical wave passes from the snakes tail to its head, and the snake propagates forward.

This snake was developed by Gui Cavalcanti, Jonathan Tse, Elizabeth Kneen, Chris Dellin and Matthew Aasted, under the direction of Gill Pratt at the Franklin W. Olin College of Engineering.

It may have originally been a sidewinder model but it's exhibiting rectilinear creeping in this video. Its used a lot by the short, fat snakes like the boas, pythons and some vipers. One set of muscles draws up the underside off the ground and shifts it forward, the other set pulls the body (within the skin) forward so it is back above the corresponding skin that has just been moved forward. The process is repeated and the movement of the skin is what ultimately moves the snake.
