This work consists of understanding the dynamics an autonomous vehicle that operates in both aerial and aquatic environments, also known as Hybrid Unmanned Aerial Underwater Vehicle (HUAUV). There is little research on operating a more than one environment, literature, underwater models are usually treated separate systems. Aiming at taking into account environment transition, this paper proposes model for transition. Studies significant effects transition zone such drag forces, Coriolis...
This paper presents a visual-based autonomous Unmanned Aerial Vehicle (UAV) capable to perform broad range of navigation tasks in indoor environments. Unlike other related vehicles, our robot does not need an external operator whatsoever or any kind off-board processing, reducing the overall workload and manual dependency. We evaluated vehicle real environment that simulates offshore oil platform scenario, demonstrating it is localize itself, maintaining stable flight, navigating, detecting...
Quadrotors have been used in diverse areas, such as agriculture, civil construction, fire monitoring, and so on. However, these vehicles cannot perform missions that require navigation aquatic environments, inspection of underwater structures water sample collection, due to their hardware limitations. Therefore, hybrid unmanned aerial-underwater emerge a feasible solution accomplish missions. Although quadrotors well-accepted mathematical models, small quantity works dealing with this topic....
This paper presents the investigation of ground effect on hybrid aerial-aquatic vehicles. The is formation an air bag, caused by thrusters during landing and taking off a propeller-based vehicle. Aerial vehicles are influenced effect, which large factor variation in turbulence flow that can significantly interfere with movements Therefore, inclusion dynamics vehicle model relevant for better comprehension transition zone between both environments: water. Simulation results show thrust force...

In the last decade, a great effort has been employed in study of Hybrid Unmanned Aerial Underwater Vehicles, robots that can easily fly and dive into water with different levels mechanical adaptation. However, most this literature is concentrated on physical design, practical issues construction, and, more recently, low-level control strategies. Little done context high-level intelligence, such as motion planning interactions real world. Therefore, we proposed paper trajectory approach...
