New methods and approaches for carrying out comprehensive measurements of hazardous waves
(tsunami, storm surges) and background wave climate with telemetrically related group of
ground, surface and underwater based robots are discussed. The design and equipment list of the
ground robot are considered. It includes three various types of movers, an add-on for the
installation of devices on the mobile platform and the hardware part. Ground robot was tested in
2016 on the coast of Sakhalin Island, cape Svobodny. Based on test results there were made
conclusions on the possibility of increasing mobility of the ground robot and expanding its use.
Specially designed underwater robot collects data using a video inspection system and a
hydrostatic wave recorder with a string sensor. It has the ability to adjust the position of the
center of gravity to increase stability when driving on steep slopes of the seabed. The surface
robot was designed for conducting detailed bathymetry measurements of investigated water areas
by means of a multi-beam echo sounder. Underwater and surface-based robots were tested in July
2017 on Sakhalin Island. Both robotic systems were merged into the united local network. The
results of their operation were obtained to verify the data from measuring systems of the ground
robot. In 2018, it is planned to conduct a series of tests involving the three robots and merging
them into a local network to manage and process data in real-time.
