You've got probably heard that honey bees - a domesticated species, Apis mellifera, that farmers depend upon to pollinate crops - have been dying off in disturbing numbers in recent times, with total hive populations disappearing in a phenomenon referred to as Colony Collapse Disorder.

But there are nearly 4,000 species of wild bees in North America, and loads of them are in trouble as properly. A research published within the journal Science in 2013, for example, discovered that half of the bee species discovered in one Illinois forest in the late 1800s have vanished.

However at the same time as there's a looming bee-pocalyse within the biological world, researchers have been making great strides in creating robotic bees which have among the skills of the actual insects - in addition to some that surpass precise bees. Finally, such tiny robots might serve a variety of makes use of, ranging from army surveillance to aiding search-and-rescue missions during pure disasters. It is even conceivable that in a pinch, they may pollinate plants.

At Harvard University, researchers have been working for more than a decade to develop the RoboBee, a tiny machine that is half the scale of a paper clip and weighs lower than a tenth of a gram. Engineering professor Robert J. Wood, founding father of the Harvard Microrobotics Laboratory, has copied the structure of precise insect wings to develop synthetic ones, made from a polymer membrane fastened to carbon-fiber supports. The RoboBee flaps its wings 120 instances per second, in the same method that an actual bee does to hover and fly.

In 2013, the researchers managed to get the RoboBee to fly for the first time. However now it could do more than that. At the current International Convention on Intelligent Robots and Programs in Hamburg, Germany, Harvard researchers presented a paper explaining how the RoboBee can land-or slightly, dive--into water. It then converts itself into an extremely tiny model of a scuba diver, flapping its wings slowly for propulsion. (Try the video at the top of this text.)

"The fascinating side is the observation that the fluid mechanics of the RoboBee wings are related for top-frequency flapping in air and low-frequency flapping in water," says Robert Wood by way of e mail. "Simply by changing the frequency upon getting into water, a similar wing movement is achieved and comparable forces are generated."

While the swimming RoboBee's worth primarily is in contributing to information about fluid mechanics, Wooden mentioned the aquatic functionality sometime might enable robotic bees for use for water-high quality monitoring.

Harvard researchers are growing tiny flying robots that can do many of the things bees do and even some things that they can not.

In keeping with a recent Nature article, one large challenge of making functioning robotic bees is powering them. The Harvard scientists reportedly have made advances in battery storage, electronics and motor technology that now permits a RoboBee to remain aloft for a couple of minutes at a time. Finally, although, future generations of robotic bees may take far longer flights, outfitted with tiny radio transmitters and international positioning methods to guide them.

Harvard's Wyss Institute for Biologically Impressed Engineering, which is concerned within the RoboBee mission, notes on its website that the synthetic insects sometime may even be pressed into service to pollinate crops. That stated, researchers estimate that it will be a minimum of another 20 years before robotic bees might act as replacements for biological ones, and then only as a stop-gap measure.

"We would be significantly better served finding and fixing the foundation causes of colony collapse disorder, as opposed to making a robotic solution to change pollinators," says Wooden.

And there's one other main obstacle: One single beehive can include 25,000 insects. That's a complete lot of RoboBees we'd want to construct.

Now That is Fascinating The U.S. Department of Agriculture blames Colony Collapse Disorder losses totally on a pest called the Varroa mite, whereas unbiased scientists and environmental activists place a lot of the blame for those losses on a category of potent pesticides known as neonicotinoids, a charge that the chemical industry denies.
