This underwater remote operating vehicle (ROV) is designed with and without tethered operation. The operator can control the ROV from the real time first-person view in graphical user interface combined with sonar and object detection function when the tether is attached to perform search and rescue. The control tether with fiber optic lighting cable establishes a guided link medium between the possible search victim location and the rescue team. When the tether is detached, rapid deployment by a predefined set of instruction to achieve further operation range. The intelligent technologies of signal processing were used for object recognition, collision detection and sonar scanning data to enhance underwater operation. Autonomous driving is based on software development with limited capability to run in unrestricted open areas. We have achieved the design intent and confirmed the performance data in the laboratory boundary conditions.
