A Reliable Control System for An Underwater Hidrojet Explorer Camera

摘要

Access to restricted spaces underwater requires a small unencumbered camera. A low cost solution has been envisaged. It consists of an hermetic capsule enclosing the camera and lights, joined to the host by an umbilical. Along the umbilical go six water carrying ducts. Three of them end at backwards pointing nozzles located at the capsule body. The jets of water flowing from the nozzles are controlled and their forces allow some restricted positioning of the camera. Another three ducts end atnozzles located some distance up the umbilical, and allow greater maneuverability.
