The Untethered #RoboBee #robots #bees [#geekgirl]

Changes to the Robobee — including an additional pair of wings and improvements to the actuators and transmission ratio — made the vehicle more efficient and allowed the addition of solar cells and an electronics panel. This Robobee is the first to fly without a power cord and is the lightest, untethered vehicle to achieve sustained flight. (Image courtesy of the Harvard Microrobotics Lab/Harvard SEAS) June 2019
