Flying Insect-like Robot
The tiny robot measures just 20 mm in height, with a wingspan of 36 mm and a weight of just 84 mg. This poses some interesting challenges when it comes to perching. There's limited space for grippers or feet, and the robot's payload is likewise small, so significantly adding to its weight will possibly inhibit flight. Led by Moritz Alexander Graule of MIT and Robert Wood of Harvard, the team developed an adhesion pad that uses an electrostatic charge. This has allowed the robot to stick to a variety of surfaces, including glass, plywood and leaves, and take off again without issue.
