Abstract
This paper introduces a notion of odometry to a snake like robot. When a snake like robot is
used for surveilance in a narrow space, such as disaster debris, the operator cannot see the robot directly.
Our goal is to realize a visualizer such that a thrid person's view of the robot appears on the display for the
operator. For that purpose, position and orientation of the robot has to be obtained by the system. This
paper describes odometry of the snake like robot,
