Aquatic Fixed-Wing Drone Could Lake-Hop Across Canada

Fixed-wing drones are the way to go for efficient flying, but they pose challenges for long term autonomy because of how demanding they are when it comes to takeoffs and landings. You need a nice big flat area, and usually you need infrastructure support. A drone that needs to operate for days or weeks at a time completely on its own can't rely on either, which means you need to get creative. At ICRA this week, researchers from the University of Sherbrooke in Canada have gotten creative, and came up with a very clever design for a fixed wing drone called SUWAVE (Sherbrooke University Water-Air VEhicle) that uses lakes as landing pads. It crash lands in them, recharges with solar power, and then takes off again with a brilliant hinged propeller.
