RoboBee the size of a paper clip. It is made of sheets of hydrocarbon fiber by laser cutting and weighs only about 80 mg. The movement of the wings (up to 120 strokes per second) is provided by a set of piezoelectric elements. Since we are talking only about the prototype prototype, its power is supplied by an external source via a wire.
To minimize energy costs, scientists again turned to nature for help. To do this, they studied in detail the flight features of bats, birds and butterflies. As a result, the researchers developed a method of “electrical sticking”. Something like this happens with a balloon if it is rubbed against the hair. The resulting small electrical potential must “glue” the ball to the ceiling.
Electro-sticking technology provides RoboBee the ability to hold on to overhanging horizontal surfaces as much as scientists need. In the future, the “descendants” of RoboBee will participate in search and rescue operations, monitor crops and even carry out spy missions.
