Sailboats are purely wind-driven and thus have great potential for long-term voyaging. For robotic sailboats, the constraints on the energy are crucial to the sustainability of automation. Reducing the control frequency of actuators is crucial for energy conservation. This study proposes an energy-e…
This paper presents a strategy for predicting the turning radius of a sailing robot with consideration of aerodynamic and hydrodynamic interferences from the marine environment. The turning radius is initially obtained based on three consecutive designated points during the turning process, which is…
Ocean observation is an emerging field, and sailing robots have several promising features (e.g., long-range sailing, environmental friendliness, energy-saving and low-noise) to perform tasks. In this paper, we define an ocean observation mission in a restricted target area as a station keeping prob…
Ensuring an adequate supply of energy is a challenge in the development of autonomous sailboats for long-range sailing capability, as the continuous high-frequency execution of control commands leads to high energy consumption. However, as the control of sailboat is much more complex than the other
Sailboats have a wide range of applications on account of their energy-saving, environmentally benign and low-noise characteristics. This has led to the increasing popularity of research in autonomous sailing robots, with concomitant attention paid to the development of methods that ensure their saf
This paper proposes a drive-through recharging strategy for a quadrotor. First, a ground charging station is constructed with a portable charging wire, then with two conductive hooks connected to the battery, the quadrotor is flying through the station. Finally, after connecting the hooks to the cha…
Obstacle avoidance is crucial for autonomous surface vehicles (ASVs) in the sea because rescue is extremely difficult there. OceanVoy, a sailboat toward long range energy-saving voyage, has to overcome the dual challenges, i.e. from the environmental interference and its low mobility preventing from…
Towards long range and high endurance sailing, energy is of utmost importance. Moreover, benefiting from the dominance of the sailboat itself, it is energy-saving and environment-friendly. Thus, the sailboat with energy planning problem is meaningful. However, until now, the sailboat energy optimiza…
