Scientists have created a tiny drone capable of pollinating plants [sciencemag.org]:
The device is about the size of a hummingbird, and has four spinning blades to keep it soaring. With enough practice, the scientists were able to maneuver the remote-controlled bot so that only the bristles, and not the bulky body or blades, brushed gently against a flower's stamen to collect pollen [cell.com] [open, DOI: 10.1016/j.chempr.2017.01.008] [DX [doi.org]]—in this case, a wild lily (Lilium japonicum), they report today in Chem. To ensure the hairs collect pollen efficiently, the researchers covered them with ionic liquid gel (ILG), a sticky substance with a long-lasting "lift-and-stick-again" adhesive quality—perfect for taking pollen from one flower to the next.
The current version is not autonomous and must be piloted by a human.
