Abstract

Design of new unmanned underwater vehicles (UUVs) is a continuous process since decades, where finding an optimal design for a specific application is still a challenging subject. New inspection class category remotely operated vehicle (ROV) is developed to overcome some disadvantages of existing ROVs of the same category. It has been taken into consideration in the new design to be small, capable of maneuvering freely in 6 DOF, closed-hull body of minimum water resistive forces, low-cost components which work with high integration, one-duct tether (at low cost) and software program to be used with any PC instead of special control station. Detailed design of the internal network that combines sensors, thrusters’ controllers, and camera of the ROV is shown and smart communication architecture between the ROV and the control station is also introduced. Finally, in the computer layer, many aspects are discussed including communication protocol between the control station and the ROV, high-precision orientation angles calculation using inertial measurement unit (IMU), heading calculation of the ROV, and GUI of the control station.

Highlights

  • Exploring the underwater environment was and still a challenging subject that has not been solved yet

  • Unmanned underwater vehicle (UUV) can be classified into two categories: autonomous underwater vehicle (AUV) or remotely operated vehicle (ROV), and each of categories can be classified according to their function into two classes: intervention and inspection [1, 2]

  • This research focuses on developing a new inspection class category ROV of 6 degrees of freedom (DOF) that overcomes some disadvantages of existing ROVs of the same category in both design and function. It has been taken into consideration in the new design to be in small size, capable of maneuvering freely in 6 DOF, closed-hull body with minimum resistive forces, low-cost components, one-duct tether at low cost with smart multiplexing of power lines and communication signal, and software program to be used with any PC instead of specialized control station

Summary

Introduction

Exploring the underwater environment was and still a challenging subject that has not been solved yet. The veg size of seas and oceans and the variety of possible application that can be done in the underwater environment makes the design of new unmanned underwater vehicles (UUVs) a continuous process. UUVs which are controlled using vectorial thrust (VT) propulsion systems are promising [3]. Some designs use single or few RTs or even combinations of both types [3, 8, 9]. This allows designers to use less number of thrusters; the ELAFF Journal of Engineering and Applied Science (2022) 69:14 additional mechanisms of RT will reduce the reliability of the system and more complicated motion control is required
