A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components(元件), ”said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”

Where did all the tigers go? That’s what Indian Prime Minister Manmohan Singh wants to know. India’s Sariska Project Tiger Reserve, once home to 26 tigers, is now home to none. Singh has ordered a police investigation into the   39 ，and created a new taskforce to save the   40  animals.
Tigers are an endangered species(物种). Half of the world’s tiger   41  live in India. For years, tigers have been disappearing from India’s national parks, but Sariska may be the last straw. And the government has to react.
On Thursday, Singh held the first meeting of   42  officials, wildlife experts, and related leaders, aiming to count the nation’s remaining tigers, and to come up with a plan to keep them safe.
It is not hard to guess why the tigers are disappearing. Poachers (偷猎者) can   43  the big cats for $50,000 each. Tiger skin and bones are popular in Chinese   44 . A single tiger tooth can fetch $120. Recently, a group of poachers admitted killing ten tigers in Sariska and were   45 .
“Indian tiger poaching is probably the biggest conservation problem in modern times.” said Belinda Wright, the head of the Wildlife Protection Society of India.
However, poaching isn’t the only   46 . Many poachers use advanced technologies, like night glasses and long–range binoculars. Forest security officers are paid so   47  that few of them bother to track down the poachers. Even if a security guard were to find a poacher, many carry only a stick to make him obey the law.
Tiger fans hope that Singh’s plans mean end for the poachers and   48  for the endangered species.
