Increasing the efficiency of underwater operations with the help of automatic machines can be achieved by using a robotic complex in a special configuration -with a functional division into three interacting parts: a remote control panel with an operator; a basic underwater walking platform, connected by a cable with the control panel for information and energy supply; a group of autonomous robots with increased maneuverability, having information communication lines with the base station via a contactless channel. Within the framework of this concept, the paper considers and solves the main problems of creating information-control systems for such robotic systems, including the necessary communication tools. One of the key solved problems was constructing the proper sensor-control real-time software system. The paper was partially supported by RFBR, projects 16-
