The U.S. scientists studying how the butterfly flaps its wings when flying from Saudi Aaron flower to flower to "teach" for a new generation of robots the size of a small insect.
These tiny flying robots will have many applications in practice. Artwork.
According Eco.ria, this study is based on the order of the Department of Defense, to manufacture the tiny flying robots (referred to as MAV - Micro areal vehicle) for reconnaissance, search and rescue as well as control environmental testing.
Researchers Tiras Lin, John Hopkins University, a member of the project, said: "To make the military operation, MAV need to be fluent in a city terrain, weaving through the ranks very narrow and flying in the air slightly. The tiny robot that must be extremely clever, flexible, even more prudent to meet the demand. "
According to him, to "teach" the MAV moving quickly and accurately in space, they must be very careful study mechanisms of butterfly flight. They use the most modern camera to analyze the motion of the wings when playing around a flower with maximum accuracy. The speed of the machine to capture up to 3000 pictures of "strokes" in a second one magepixel meet the new requirements (for comparison reiterate that a camera normally only taken 24, 30 and 69 in Figure 1 second).
Mr Lin said: "We had to use a camera with high-speed video recording such as a second butterfly waving its wings 25 times".
Scientists put the camera in front of a transparent shield and release butterflies. When the butterfly flew into the "sights" of the three cameras arranged at three different angles, will turn to acquire about 6,000 in 3-dimensional image of the new space flight mechanics analysis of the butterfly. Butterfly than body mass so small that its inertia does not affect the flight.
The meticulous research of the John Hopkins University researchers will lead to the birth of a new generation of robots that people can not imagine all of our applications, but is used for immediate military purposes.
