Abstract

Bottom-following, or maintaining a fixed altitude above an arbitrary surface, is important for underwater vehicles particularly those that survey large geographic areas. This feature is necessary for numerous tasks, including side-scan sonar mapping, photographic surveys, magnetic surveys and maneuvering in and around both manmade and natural structures. Current research at the MIT AUV Laboratory, starting with the simplest bottom-follower and moving through multiple iteration with successive improvemetns, is described. Along with results from various field tests with autonomous underwater vehicles, the paper presents findings from several simulations.
