“…The AUVs run a full-fledged Dune implementation of the LSTS control architecture ( [18], [20]) on the on-board primary computer. The X8-based UAS ( [10], [11], [17]), developed at LSTS, implements the high levels of the LSTS architecture on a small form-factor computer board which interfaces with the Ardupilot auto-pilot. The X8-based UAS is capable of sending high-resolution video stream to a ground station equipped with a directional antenna.…”

The paper describes the Rapid Environmental Picture Atlantic exercise 2014 (REP14-Atlantic), with special focus on the experiments with autonomous underwater, surface and air vehicles, and discusses how large scale experimentation in operational environments is contributing to advancing the state of the art in networked vehicle systems. REP14-Atlantic was also focused on collaborative experimentation to advance interoperability, underwater communications and disruption/delay tolerant networking (DTN) capabilities, automation and cooperation of unmanned underwater, surface and aerial vehicles. In addition some of these vehicles had deliberative planning capabilities onboard for unprecedented levels of autonomy. Deliberative planning techniques were also used to support coordinated planning and execution control of multiple vehicles.978-1-4799-8736-8/15/$31.00 ©2015 IEEE

“…Unmanned aerial vehicles (UAV) are continuously increasing in value as tools and are useful aids for a multitude of human activities. These activities, scenarios, and concepts nowadays cover a wide range of contexts from the multi-vehicle oceanographic environment [1,2,3] to smart farming [4,5], surveillance [6,7,8,9], wildfire tracking [10,11], or transportation [12,13]. These systems have, through miniaturization and reduction in cost, become more attractive and viable especially for tasks which might pose a danger to humans or tasks which are, in their essence, logistical burdens to carry out continuously in a manual manner.…”

This paper addressed the challenge of exploring large, unknown, and unstructured industrial environments with an unmanned aerial vehicle (UAV). The resulting system combined well-known components and techniques with a new manoeuvre to use a low-cost 2D laser to measure a 3D structure. Our approach combined frontier-based exploration, the Lazy Theta* path planner, and a flyby sampling manoeuvre to create a 3D map of large scenarios. One of the novelties of our system is that all the algorithms relied on the multi-resolution of the octomap for the world representation. We used a Hardware-in-the-Loop (HitL) simulation environment to collect accurate measurements of the capability of the open-source system to run online and on-board the UAV in real-time. Our approach is compared to different reference heuristics under this simulation environment showing better performance in regards to the amount of explored space. With the proposed approach, the UAV is able to explore 93% of the search space under 30 min, generating a path without repetition that adjusts to the occupied space covering indoor locations, irregular structures, and suspended obstacles.

“…With our increasing need to understand and monitor how key maritime issues [1] steps must be taken to streamline and facilitate our ability to operate in this environment. One way to address this issue has been through the ongoing use of autonomous systems, both aerial, surface and underwater [2], [3], [4], [5], working in tandem with each other as a team. The use of teams of autonomous systems has not only allowed for easier operational logistics, but also expanded what can be done within the maritime environment [6], [7], [8].…”

With the rise in the use of multi-vehicles teams, for maritime operations, new challenges and opportunities arise regarding the complexity and logistics of these scenarios. One way to cope with said complexity is to imbue some of these systems with the versatility of operating in more than one physical medium (air/water/land) during its normal mission cycle, maximizing their possible mission roles. The ability of having a vehicle which can operate both in the air and on the water can further expand and facilitate maritime operations by allowing new sampling, deployment and even communication scenarios. This work follows the iterations of a specific vehicle concept, through its various phases, and tracks the developments and challenges necessary to adapt a Remotely Piloted Aircraft Systems (RPAS) to become capable of water take-off & landing, and explores its applicability as a viable operational mobile communication gateway for underwater and surface assets.
