Several RoboBees sit on the ground, while another is held in tweezers with the wings activated. RoboBee is a tiny robot capable of partially untethered flight, developed by a research robotics team at Harvard University. The culmination of twelve years of research, RoboBee solved two key technical challenges of micro-robotics.
Evolution of the ways the wings at rest to the body to create wings do not fold back (recent Archaeoptera) spread laterally (large bubbles) over the back against one another (damselflies, mayflies) Folding (Neoptera) wings not foldable (e.g., stoneflies) Folding fan-fold (e.g., front wings of wasps) Cross fold (such as the rear wing of the beetle)
Drone bee. A drone is a male bee. Unlike the female worker bee, a drone has no stinger. He does not gather nectar or pollen and cannot feed without assistance from worker bees. His only role is to mate with a maiden queen in nuptial flight.

A more detailed analysis of the problem shows that the work done by the wings is converted primarily into kinetic energy of the air that is accelerated by the downward stroke of the wings. The power is the amount of work done in 1 s; in the insect used as an example, makes 110 downward strokes per second.

Step 2. Locate and tuck the wings: Locate the joint where each wing meets the body of the turkey by gently lifting the wings. Now imagine you're laying back on the grass with your arms tucked ...
The wings are transparent, often hyaline or evenly colored or with bands. The alula are well developed and in the rest position the wings are kept open and horizontal in a V shape revealing the sides of the abdomen. The abdomen is generally short and wide, subglobose-shaped, cylindrical, or conical, composed of six to eight apparent urites.
