About

I was born on April 13, 1994 in Starokostyantyniv, Ukraine. In 2004 I emigrated to Portugal where I live nowadays.

In 2015 I concluded my Bachelor’s degree in Electronics and Computers Engineering at Instituto Superior de Engenharia do Porto.

After that, I started the Master degree in Electrical Engineering, a branch of Autonomous Systems at Instituto Superior de Engenharia do Porto.

I am a researcher at INESCTEC since January 2018, working with Underwater Robotics System and Simulation, in particular in the UNEXMIN project.

Abstract
This paper addresses the problem of high-bandwidth communication and data recovery from deep-sea semi-permanent robotic landers. These vehicles are suitable for long-term monitoring of underwater activities and to support the operation of other robotic assets in Operation & Maintenance (O&M) of offshore renewables. Limitations of current commu-nication solutions underwater deny the immediate transmission of the collected data to the surface, which is alternatively stored locally inside each lander. Therefore, data recovery often implies the interruption of the designated tasks so that the vehicle can return to the surface and transmit the collected data. Resorting to a short-range and high-bandwidth optical link, an alternative underwater strategy for flexible data exchange is presented. It involves the usage of an AUV satellite approaching each underwater node until an optical communication channel is established. At this point, high-bandwidth communication with the remote lander becomes available, offering the possibility to perform a variety of operations, including the download of previously recorded information, the visualisation of video streams from the lander on-board cameras, or even performing remote motion control of the lander. All these three operations were tested and validated with the experimental setup reported here. The experiments were performed in the Atlantic Ocean, at Setúbal underwater canyon, reaching the operation depth of 350m meters. Two autonomous robotic platforms were used in the experiments, namely the TURTLE3 lander and the EVA Hybrid Autonomous Underwater Vehicle. Since EVA kept a tether fibre optic connection to the Mar Profundo support vessel, it was possible to establish a full communication chain between a land-based control centre and the remote underwater nodes. © 2024 IEEE.
