Vision and Aims The scientists anticipate the devices will open up a wide range of discoveries and practical innovations, advancing fields ranging from developmental biology to amorphous computing and electrical engineering. Body The team Robobee The secrets of bee flight How does it work? In the last 10 years, flight biologists have gained a remarkable amount of understanding by shifting to experiments with robots that are capable of flapping wings with the same freedom as the animals. As a bee takes flight, air swirls in a tight circle, a vortex, over the leading edge of the wing.The vortex is a low pressure region above the wing, and it sucks the wing upwards.This is what gives the bee the extra bit of lift it needs to buzz around from flower to flower. The scientists analyzed pictures of bees and mimicked the movements using robots with sensors for measuring forces.
The honeybees have a rapid wing beat: they flap their wings 230 times every second. A honey bee's wings are arranged in two pairs that are coupled together by a row of hooks on the hind wing that grip in a groove.As the wings unfold for flight the hooks automatically fall into the groove and lock the two wings into a single aerofoil surface. Worker Queen Drone Researchers forced the bees to fly in a small chamber filled with less dense air. This required the bees to work harder to stay aloft.
The bees made up for the extra work by stretching out their wing stroke amplitude but did not adjust wing beat frequency. Practical Applications Robotic Bees Interesting facts about bees: by Nathan Wildenberg This is the robotic bee,no bigger than a coin: "If bees were to disappear, man would live only a few more years.",Albert Einstein.
For 50 million years since they appeared on Earth, bees have contributed greatly to the evolution of the plant kingdom, as we know it today. Bees are flying insects closely related to wasps and ants, and are known for their role in pollination and for producing honey and beeswax. Department of Organismic and Evolutionary Biology in the Faculty of Arts and Sciences at Harvard and Northeastern University’s Department of Biology and Centeye, a microelectronics firm, will contribute technical knowledge. Bees the maximum speed of a bee in flight is 70 km per hour;
a honeybee travels about 400km to bring 10g of honey;
range of activity of a bee is about 3-6km; http://robobees.seas.harvard.edu/
