Generalized Method of Designing Unmanned Remotely Operated Complexes Based on the System Approach

Abstract

Self-propelled underwater systems belong to the effective means of marine robotics. The advantages of their use include the ability to perform underwater work in real time with high quality and without risk to the life of a human operator. At present, the design of such complexes is not formalized and is carried out separately for each of the components – a remotely operated vehicle, a tether-cable and cable winch, a cargo device and a control and energy device. As a result, the time spent on design increases and its quality decreases. The system approach to the design of remotely operated complexes ensures that the features of the interaction of the components of the complex are taken into account when performing its main operating modes. In this paper, the system interaction between the components of the complex is proposed to take into account in the form of decomposition of “underwater tasks (mission) – underwater technology of its implementation – underwater work on the selected technology – task for the executive mechanism of the complex” operations. With this approach, an information base is formed for the formation of a list of mechanisms of the complex, the technical appearance of its components is being formed, which is important for the early design stages. Operative, creative and engineering phases of the design of the complex are proposed. For each phase, a set of works has been formulated that cover all the components of the complex and use the author's existence equations for these components as a tool for system analysis of technical solutions. The perspective of the scientific task of the creative phase to create accurate information models of the functioning of the components of the complex and models to support the adoption of design decisions based on a systematic approach is shown. The obtained results form the theoretical basis for finding effective technical solutions in the early stages of designing remotely operated complexes and for automating the design with the assistance of modern applied computer research and design packages.

Application of systems approach at early stages of designinng unmanned towed underwater systems for shallow water areas

“…The necessity of introducing the systems approach in the design of underwater robotics was most completely formulated in [17]. In their example of designing unmanned self-propelled attached underwater complexes, the authors considered systematic interaction between the complex components as a decomposition of its basic operations.…”

“…where H TT , Q TT are maximum values of the working depth of the TUA immersion and its performance in the search, respectively, specified in the RS. Dependence ( 9) should be checked with the use of mathematical and computer simulation methods that allow one to study force-and-power, information and operation characteristics of the created TUA (C RT requirement of the C UTUS set) [17,18].…”

Construction of a mathematical model to describe the dynamics of marine technical systems with elastic links in order to improve the process of their design

“…An example of MTS is the class of marine tethered systems (MTdS), which in turn includes underwater self-propelled tethered systems and underwater towed systems (UTS) [1,2]. When designing and operating MTdS with self-propelled underwater vehicles (SUV), the stationary problems in which objects occupy an unchanged position in space with constant flow characteristics and perceive external loads that are constant in time, are quasi-static.…”
