Purpose Of Review: Starting from late 1990s, new marine robotics competitions have spread around the world. Today, the importance of competitions for both educational purposes and technological innovation is widely recognised by the community. In this paper, we present an overview of this kind of challenges, using the most representative events to describe common trends and unique aspects.
Recent Findings: Recently, competitions have been in a rapid evolution. Trends are the increasing popularity of Grand Challenges, the push for autonomous decision-making, the introduction of multi-domain cooperation and the birth of virtual competitions. More attention has been given to the scientific aspects, stressing the benchmarking/metrological perspective. Finally, forums and workshops are currently seen as a way to complement competitions and to create a community of interest.
Summary: Marine robotics competitions enable junior and expert teams to acquire experience in realistic environments. Virtual competitions can help in this aspect. They are useful for preparing team participation in the physical events, especially for open sea competitions. They allow teams to focus on advancing vehicle autonomy. Furthermore, they are important to widen the marine community attracting other robotics and AI experts.

As advancements in autonomous underwater vehicle (AUV) technology unfold, the role of underwater wireless sensor networks (UWSNs) is becoming increasingly pivotal. However, the high energy consumption in these networks can significantly reduce their operational lifespan, while latency issues can impair overall network performance. To address these challenges, a novel mixed packet forwarding strategy is developed, which incorporates a wakeup threshold and a dynamically adjusted access probability for the cluster head (CH).

The Mediterranean basin is the second largest global biodiversity hotspot in the world, which coexists with a plethora of anthropogenic stress. This study examines the risks that marine litter poses to Mediterranean biodiversity, using the Special Protection Area of Mediterranean Importance (SPAMI) "Pelagos Sanctuary" as a case study. In this paper, a new survey method and data analysis strategies to assess the impact of marine litter, including microplastics, on Mediterranean organisms, is proposed.

Introduction: Subsea applications recently received increasing attention due to the global expansion of offshore energy, seabed infrastructure, and maritime activities; complex inspection, maintenance, and repair tasks in this domain are regularly solved with pilot-controlled, tethered remote-operated vehicles to reduce the use of human divers. However, collecting and precisely labeling submerged data is challenging due to uncontrollable and harsh environmental factors. As an alternative, synthetic environments offer cost-effective, controlled alternatives to real-world operations, with access to detailed ground-truth data.

The inherent challenges of robotic underwater exploration, such as hydrodynamic effects, the complexity of dynamic coupling, and the necessity for sensitive interaction with marine life, call for the adoption of soft robotic approaches in marine exploration. To address this, we present a novel prototype, ZodiAq, a soft underwater drone inspired by prokaryotic bacterial flagella. ZodiAq's unique dodecahedral structure, equipped with 12 flagella-like arms, ensures design redundancy and compliance, ideal for navigating complex underwater terrains.
