Why go to all the trouble of designing and building a drone（无人机） if nature has already done most of the job for you? That is the attitude taken by the small but determined band of rearchers who are trying to roboti（机械化） incts. Some are working on turning incts like beetles（甲虫） into such cyborgs浓汤宝的用法（半人半机器的生物）汉字之美—perhaps for u in military inspection or spying. Others prefer to concentrate on the fearful side of entomology（昆虫学）, by taking electronic control of cockroaches（蟑螂）.
The first cyber-roach（赛博蟑螂） goes back to 1997, when Shimoyama Isao of Tokyo University nt electrical signals to a cockroach's antennae（触角）, causing it to turn either left or right depending on which antenna was stimulated. Others have built on this approach by recruiting extra n organs, such as the rear-facing cerci（后向尾须）. They have also begun fitting the incts with instrument packs that might let them do a uful job: arching collapd buildings for survivors.
慰问困难党员简报One such is Sato Hirotaka of Nanyang Technological University, in Singapore. He has been working on cyber-incts for 15 years. Now, he has added another twist to cyber-roaches. Instead of having their movements dictated by remote control, his are autonomous agents. They are run by algorithms（算法） that respond directly to nsors in their backpacks.
The incts thus fitted out by Dr Sato are Madagascar hissing（发声） cockroaches, which are about 6cm long. The backpacks contain a communications chip, a carbon-dioxide nsor, a motion nsor, an infrared（红外线） camera and a tiny battery.
Relead into the rubble质检员考试（碎石）, to crawl their way through while arching for signs of life such as movement, body heat and higher CO2 levels from breathing. The artificial intelligence that decides whether a t of signals actually indicate the prence of a human being is programmed directly into the camera. If it thinks it has spotted someone, it alerts a rescuer.
To test this arrangement, Dr Sato and his team ran trials in a simulated disaster zone. They laid out concrete blocks of various shapes and sizes in an area of 25 square metres. Among the were a number of people, and also some decoys(诱饵), such as a heat lamp, a microwave oven and a laptop. They then relead the cyber-roaches, having first programmed into them the arch's start and end points. The software proved able to recogni humans correctly 87% of the time, a success rate Dr Sato thinks could be红警2怎么玩 improved still further by collecting multiple images from different angles.
The next pha of the project is to refine the system for u out of doors. That done, ma
nufacture of the backpacks and automation of their attachment (附加装置)to the incts will need to be commercialid（商业化）. If all goes well, Dr Sato predicts the result could be available for u within five years.
