Large oil and half of gas reserves are distributed along the sea shelves of the Russian Federation. Hydrometeorological conditions make impedes the search and development of new deposits on the shelves. This happens due to frequent storms and intense sea waves. Therefore, nowadays stationary automated systems are used for monitoring the environment in the shelf zone of the Sea of Okhotsk near Sakhalin Island. But this provides data only for specific areas of operation. This disadvantage can be eliminated by using groups of remotely controlled mobile robots. Moreover, mobile vehicles should be able to move around the entire variety of operating conditions. Therefore, in this paper, the results of research on the development and creation of effective chassis designs for coastal areas and adjacent water areas of Sakhalin Island are summarized. The technique of choosing the design parameters of vehicles and calculating the efficiency of the system as a whole is given. Data about physical and mechanical characteristics of soil and gravel bases in the coastal zone were used for calculating the permeability of vehicles. To create a multi-agent coastal monitoring system, it is planned to use several ground, underwater and overwater robots that have the ability to exchange information in real time. The scheme of functioning of mobile ground, underwater and overwater robots basing in structure of group is shown. The advantages of group application of mobile robots in the indicated tasks are as follows: the bigger range of action achieved by dispersing robots throughout the work area; high probability of accomplishing the task, achieved due to the possibility of redistribution of goals between the objects of the group; the ability to perform measurements at several locations simultaneously.
