This chapter provides an overview of the state of the art of snake-like (backbones comprised of many small links) and continuum (continuous backbone) robots. The history of each of these classes of robot is reviewed, focusing on key hardware developments. A review of the existing theory and algorithms for kinematics for both types of robot is presented, followed by a summary ofmodeling of locomotion for snake-like and continuum mechanisms.

Shows rapid deployment of a continuum robot inside a tube using force sensing at the backbones and a generalization of the compliant motion controller initially presented in [1]. This experiment is associated with [2] which is not published. The algorithms have been validated successfully on two cadavers as reported in Hamlyn 2013 paper and in a TBME paper currently under review
