Automatic Orientation Control Device for Underwater Divers

Abstract

This study deals with the development of an orientation device that enables the working diver to control and maintain automatically his spatial orientation underwater. The device can be useful during welding or grinding of ship hulls, salvaging operations, and any underwater activity when a specific special orientation improves the diver’s performance. The device utilizes the natural forces of buoyancy and gravity in its operation to reduce the power requirements and to assure stable performance. Underwater evaluation of an optimally designed prototype of the system shows good potential for the device as a useful tool for the working diver.
