The agile biomimetic autonomous underwater vehicle (AUV), named RoboFish, is made up of several self-contained modules with self-managed battery and actuator control for full-body, autonomous movement around underwater structures, enabling efficient offshore inspections in harsh and hard-to-reach environments. RoboFish was initially devised by researchers at the University of York, Department of Electrical Engineering and the University of Strathclyde, Department of Naval Architecture, Ocean & Marine Engineering with grant support from the EPSRC Supergen Offshore Renewable Energy Hub.

With the limited accessibility, manoeuvrability and environmental impact of remotely operated vehicles (ROVs) and some larger AUVs, inspection of structures in the underwater environment is complex, expensive, and reliant on human input. As the number of offshore structures is set to increase significantly with rapid growth in the offshore wind sector, robotic offshore inspections in harsh environments will need to become less reliant on human input and be more cost effective as compared to traditional inspections.

Dr. Mark Post, lecturer in electronic engineering at the University of York said, “Through the use of innovative electronics, actuation, networking technology and additive manufacturing techniques, we have been able to develop a modular robot that can move very precisely in challenging offshore environments. The collaborative contributions of many partners have been instrumental in creating a practical platform to further develop robotic technologies in this field.”

Verlume is assisting with the development of an intelligent power solution for RoboFish. The company will supply an underwater power system for charging, as well as an integrated intelligent battery management system. Both have been designed for the harsh underwater environment, providing a reliable, uninterrupted power supply for use on the seabed.

Paul Slorach, business development director at Verlume said, “With an increasing focus on decarbonisation and the automation of high-risk underwater tasks in the so-called Blue Economy, RoboFish is an example of how these operations can be revolutionised. We are pleased to act as the industry gateway for our academic partners in this project and share our expertise to integrate Verlume’s intelligent battery system as the power solution for RoboFish.”
