'flap wings' is correct and usable in written English.
You can use it when talking about the action of a bird, insect, or other animal flying. For example: The eagle gracefully glided through the air, its wings flapping with ease.
Similarly, Flappy Bird is based around a simple interaction: press screen to flap wings.
It requires very high-powered motors to flap wings or drive a propeller, and given the effect that wind can have on such small objects, there are major control issues.
In Tim Lewis's world, bizarre kinetic sculptures move, flap wings, draw and even walk around.
Since it is not practical to build a flying platform that can directly convert the biomass into energy needed to flap wings at the moment, we had to come up with a different option to "feed" Robo Raven.
You will learn programming constructs such as repetition (calculating how many steps a person needs to walk to their car), selection (deciding which animal is the tallest), and organizing data (grouping penguins to waddle together), along with how to control objects (raise hands, flap wings, move, turn, spin, walk, etc.).
Inspired by insect flapping wings, a novel flapping wing rotor (FWR) has been developed for micro aerial vehicle (MAV) application.
These results highlight the necessity for modal testing of robotic flapping wings.
Spanwise twist can dominate the deformation of flapping wings and alters the aerodynamic performance and power efficiency of flapping wings by changing the local angle of attack.
Cellulose films could provide flapping wings and cheap artificial muscles for robots.
The company is developing tiny insect-like UAVs, or drones, with flapping wings instead of rotors.
In this paper, we used MEMS technology to fabricate the flapping wings.
