The monocopter we're looking at here, called F-SAM, comes from the Singapore University of Technology & Design, and we've written about some of their flying robots in the past, including this transformable hovering rotorcraft. It's an inherently stable design, meaning that it'll spin all by itself and do so in a stable and predictable way, which is a nice feature for a drone to have-if everything completely dies, it'll just spin itself gently down to a landing by default. The ability to spin slows the seeds' descent to the ground, allowing them to spread farther from the tree. This type of drone is called a monocopter, and the design is very generally based on samara seeds, which are those single-wing seed pods that spin down from maple trees. And if you make that airfoil flexible, you can even fold the entire thing up into a sort of flying robotic swiss roll.

Maybe that kind of stuff works for people with more funding than they know what to do with, but for anyone trying to keep to a reasonable budget, all it actually takes to make a flying robot is one single airfoil plus an attached fixed-pitch propeller. Flying robots are usually way, way, way over-engineered, with ridiculously over the top components like two whole wings or an obviously ludicrous four separate motors. It turns out that you don't need a lot of hardware to make a flying robot.
