Harvard's new RoboBee can fly in and out of water

Apparently, we haven't seen RoboBee's final form yet. Harvard researchers introduced the robot back in 2013 and developed a version that uses static to stick to walls in 2016. Now, the scientists have created an upgraded robotic bee that can fly, dive into water and hop right back up into the air. That's a lot tougher than it sounds, since the tiny machine is only two centimeters tall and is about one-fifteenth the weight of a penny. For such a small robot, swimming in water is like swimming in molasses and breaking through the water's surface is akin to breaking through a brick wall. To solve the issue, the researchers from Harvard Wyss Institute and John A. Paulson School of Engineering designed new mechanisms that make it possible for the RoboBee to transition seamlessly from water to air.
