In recent years, UAVs have evolved significantly due to technological progress. The group Liquid Robotics demonstrated his UMV (Unmanned Maritime Vehicle) a drone named Wave Water Gilder.
Wave Glider at first glance looks like a surfboard. Anything but trivial, it is a robotic vehicle capable of moving over the sea without a pilot on board. It can be controlled remotely from a web site. Its use is mainly the patrol, search and rescue. Wave Glider works by exploiting two renewable energy sources: sun and waves. It is equipped with solar panels that recharge the battery during the day and immersed fins that take advantage of tidal waves.
