The Robobee flies solo #drone #droneday

This petite drone made its first untethered flight! Via The Harvard Gazette:

“This is a result several decades in the making,” said Robert Wood, Charles River Professor of Engineering and Applied Sciences at SEAS, core faculty member of the Wyss Institute, and principle investigator of the Robobee project. “Powering flight is something of a Catch-22 as the trade-off between mass and power becomes extremely problematic at small scales where flight is inherently inefficient. It doesn’t help that even the smallest commercially available batteries weigh much more than the robot. We have developed strategies to address this challenge by increasing vehicle efficiency, creating extremely lightweight power circuits, and integrating high-efficiency solar cells.”

In all, the final vehicle, with the solar cells and electronics, weighs 259 milligrams (about a quarter of a paper clip) and uses about 120 milliwatts of power, which is less power than it would take to light a single bulb on a string of LED Christmas lights.

Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.
