“…17 Various monohull ASVs 21,22 and catamaran ASVs 23,24 have been developed. Also various autonomous sailing boats have been developed, 25,26 including fixed wing-sail vessels, for example, Elkaim 27 , Cokelet, 28 and a retractable wing sail platform that can submerge. 29 Furthermore, several wave propelled platforms have been developed, for example, AutoNaut 21 , Wave glider.…”

This paper presents a concept design for an Autonomous Vehicle (AxV) capable of operating throughout the ocean space; air, surface and subsea. With current autonomous platforms limited in their operation, for example aerial platforms only operate in air, ASVs only operate on the ocean surface and AUVs operate subsea, a platform which can operate, transiting and transitioning in and between air, surface and subsea, providing increased mobility is very attractive. In this paper, a novel AxV platform is described. The governing equations are presented, describing each operational mode and the transitions between modes (air to surface, surface to subsea, subsea to surface, surface to air). Results are presented based on the dimensions of existing vehicles, showing that the system is theoretically feasible.

“…They started with the AROO, which was a monohull 1.5-m long sailboat with one aluminum wing sail, aiming to prevent the break or jam of rope required to control traditional fabric sail. Two tests were conducted in a small lake, and issues, for e.g., frequent overshooting in sail control and long rudder action time were raised ( Sauze and Neal, 2006 ). In 2006, ARC was developed, with a monohull in a similar dimension, but two lighter wing sails were made from acrylic and wood ( Neal et al, 2009 ).…”

“…In the test, when the two sails were positioned appropriately, ARC demonstrated stable-sailing capability and followed a straight course, even if the control system was off. This showed the potential to further reduce power consumption ( Sauze and Neal, 2006 ). In ( Benatar et al, 2009 ), Neal collaborated with researchers from the University of Nottingham, University of York, and University of Reading and designed a P-controller as an expert system for maneuvering rudderless sailboats with two masts that can steer with sails only.…”

“…The MOOP ( Sauzé and Neal, 2011 ), with its R&D work starting from 2008, was a type of 0.72-m long sailboat integrating the advantages in both AROO and ARC. Its small, cheap, robust, and light-weighted features were attractive to the team, motivated by building a fleet of MOOPs and increasing the probability of crossing the Atlantic, though had not participated yet.…”

Sailing robots can contribute significantly to maritime surface exploration, due to its potential for long-range and long-duration motions in the environment with abundant wind. However, energy, the critical factor for their long-term missions, shall be carefully investigated, so as to achieve sustainability in distance and time. In this survey, we have conducted a comprehensive investigation on numerous sailing robots, developed in academia and industry. Some of them have achieved long-term operation, and some are motivated by, but still on the way to this ambitious goal. Prototypes are grouped in each team, so as to view the development path. We further investigate the existing design and control strategies for energy sufficiency from three perspectives: actuation, harvesting, and energy management. In propulsion and steering, i.e., two major actuations, researchers have accumulated effective sail and rudder designs. The motorized propeller and wave-glider–inspired mechanism also contribute as compliments for propulsion. Electricity harvesting based on solar or wind energies is also discussed to gather more power from nature. Pros and cons in strategies of energy management, which are valuable tools to enhance power utilization efficiency, are elaborated. This article is hoped to provide researchers in long-term robotic sailing with a comprehensive reference from the perspectives of energy.

“…This configuration also allows to adjust the angle of attack of the wingsail in relation to the wind, according to the wind speed and, thereby, vary the resulting force. This avoids other aspects of traditional sail control, such as mast raking, reefing, control of luffing and sail shape adjustment, and allows a reduction in power consumption [20].…”

Ocean exploration and monitoring with autonomous platforms can provide researchers and decision makers with valuable data, trends and insights into the largest ecosystem on Earth. Regardless of the recognition of the importance of such platforms in this scenario, their design and development remains an open challenge. In particular, energy efficiency, control and robustness are major concerns with implications in terms of autonomy and sustainability. Wingsails allow autonomous boats to navigate with increased autonomy, due to lower power consumption, and greater robustness, due to simpler control. Within the scope of a project that addresses the design, development and deployment of a rigid wing autonomous sailboat to perform long term missions in the ocean, this paper summarises the general principles for airfoil selection and wingsail design in robotic sailing, and provides some insights on how these aspects influence the autonomous sailboat being developed by the authors.
