Strong adhesive force gecko robot Express reporter Zhao Jieshe Scorching summer,http://hasehiro.info/ticket/ticket.cgi, flexible and comfortable gecko crawling on the walls, waiting to catch prey. Today, bionic structure and material Protection Institute of Nanjing University of Aeronautics and Astronautics Dai Zhendong After four years of research, finally developed a "gecko robot." Yesterday, the Express correspondent in Southern saw this amazing robot, erected on the whiteboard was 90 degrees, it Rulvpingdi, go step by step, steadily Dangdang. Experts said the next step they will continue to improve and strive to make the robot walk through the ceiling. Future, it is expected to work in space, disaster relief, archeology and other fields Quest to flex its muscles. □ Express reporter Xie Jingxian "Gecko robot" three characteristics ● strong adsorption force, covered with bristles made of special materials of "feet" on. ● gecko's gait, go more secure. ● petite, agile, can participate in relief and archaeological work. Experts decryption It is understood that this "gecko robot" now represents the highest domestic level. It is also one of the research by the National High Technology Research and Development Program (863) funded during the "Eleventh Five-Year", just last week invited to participate in the national "Eleventh Five-Year" major scientific and technological Exhibition. Yesterday, the Express correspondent in Southern saw this amazing robot, was 90 degrees in a ruffled white, it still climb steadily Dangdang. News & Events Southern experts create "gecko robot" Summer nights, we can often see such a scenario: the whole body under the eaves of gecko firmly glued to the wall,http://0771r.com/home.php?mod=spacecp&ac=blog&blogid=, even if there is only one toe close to the wall, it will not fall off. What is the reason it has this ability to make gecko, Dai Zhendong's curiosity was piqued out. Subsequently, Dai Zhendong access to a wealth of information, "In the beginning everyone thinks similar gecko feet sucker, have such a strong adhesive force, but later found not the case." Dai Zhendong told reporters observed under high power microscope, it will found on gecko toes and feet covered with thin and soft hair, called "bristle." Such hair only nanometers in size, ordinary thousandth the thickness of a human hair,http://www.fcperivegauche31.org/spip.php?article96,Piumini moncle, the human eye can not make out. This extremely soft fine hair can produce an adhesive force between molecules - van der Waals forces. "Because of this, the gecko can firmly adsorbed smooth glass on the wall even." Dai Zhendong said adsorption ability of flies and mosquitoes, and gecko largely similar principles are basically the same. However, because the flies, mosquitoes too tall, observe them very troublesome, difficult to counterfeit bigger robot. To make gecko robot, you must first understand gecko. Starting a few years ago, the group received a batch of gecko from Guangxi shipped to China Southern Airlines, leisurely stay in the breeding room,http://www.8liuxing.com/home.php?mod=spacecp&ac=blog&blogid=, serve them is a group of master's and doctorate. This gecko big, only Guangxi, commonly known as Gecko. Feeding room designed specifically for cages, but also the placement of a rockery, two pieces of black cloth hung on the wall, "They like to hide behind the black cloth." Dai Zhendong said the students love red guitar. Reporters saw, this length of nearly 20 cm gecko, looks like just born near the small crocodile. "To ensure the breeding room temperature 16 ~ 20 ℃, and 70% to 80% humidity, which is to imitate Guangxi climate." Kat love Hung,spaccio peuterey,http://www.democratie-socialisme.org/spip.php?article3346, indoor must ensure clean, every once in a while they would help clean up the house. We had to feed them every day to eat three meals mealworms. After four years of hard study, gecko robot has finally arrived. Follow the instructions gecko can really learn to walk Before developed a "gecko robot", Professor Dai Zhendong who have made "live gecko robot." According to reports, the animal movement generally through the brain's neural networks to control different areas carry out their duties. For example, the "brain" will command gecko turn left, another "brain" command it right. Let the gecko turn left,canada goose femme, you have to stimulate it, "left brain", turn right on stimulating its "turn right brain regions." Thus, experts microelectrodes implanted chip in live gecko corresponding brain areas, issuing remote commands pulse "control" gecko to these brain areas through the chip. Well, today's the gecko robot can do it like a real gecko to walk it? "We support the gecko, is to study its gait, sports law, and then imitate." Institute for Youth Research backbone Yu Zhiwei told reporters that the school has a total space of animal movement behavior - reaction force tester, which is the world's first Analysis can be used to record motion foot reaction force between animal behavior and movement coordination laws of science instruments. Through this instrument, gecko gait, strength and so on can be measured. This instrument has on a large flat panel has 24 small box, which is a three-dimensional force sensor. "The gecko crawling on top, standing on its feet as long as the small squares, the computer will measure the contact force, the adhesion." Yu Zhiwei introduced tablet can rotate, tilt can mimic different floors, walls and ceilings Spatial surface angles, that is, whether it is on the ceiling or the state gecko fell on the 90-degree vertical walls can be measured out. At the same time, there is a high-speed camera, synchronized recording will gecko gait on the instrument down. Through testing, Yu Zhiwei found gecko gait lot. When climbing faster, diagonal movement, left foreleg and hind foot away from the wall, forward,http://www.88822.com/#03666/read.php?tid=980, talk to the other two legs. When there is a triangular slow gait, one foot off the ground to step forward, alternating forward. Yu Zhiwei said they would instrument measured the gait of gecko movement, intensity and other information entered into one chip, then install the robot body, so the robot will be able to follow the instructions, "learning" gecko walk. On the whiteboard erected, it is very steady climb How to make the robot adsorbed on the walls, this is a very big problem. "There are a lot of places are doing the gecko robot,http://www.xinhelan.com/home.php?mod=spacecp&ac=blog&blogid=, but basically using a suction cup and magnetic style, not authentic." Dai Zhendong said that sucker to adhere to the smooth surface, and magnetic Suction also have to face in the iron to work. So, he decided to mimic gecko feet bristles. After the study period, Dai Zhendong counterfeit material with a special bristles, "yet can not disclose specific material situation, but this material is very soft bristles can imitate." However, Dai Zhendong also admitted that currently there are no foreign less imitation bristles method, there is a production of carbon nanotubes bristle best, adsorption can be done even 10 times the natural gecko. Subsequently, the staff will "gecko robot" took out. In the reporter's repeated requests, the staff finally agreed to allow reporters to touch "gecko robot" feet. The surface looks, "foot" is like a layer of smooth double-sided adhesive, are they not see the furry feeling. Hand feels, somewhat sticky. Robot about 40 centimeters, pointy head, long tail. Staff will be a smooth ruffled whiteboard was 90 degrees, and the robot put up, the physique is not a small guy really stick in the board, did not decline. After power, "Gecko" start up slowly crawling along a whiteboard, a step from the left front foot, forward stride, the right hind also simultaneously keep up, followed by the other two legs alternately again. In this way, about a minute,air max femme pas cher, "Gecko" climbed to the top of the whiteboard. And on uneven ground, "gecko" can move freely, step by step very stable, this comparable wheeled robot is much easier. "Now the crawling speed is also relatively slow, we are mainly seeking stability, to secure it fall off." Yu Zhiwei explained that from 2007 they officially do gecko robot, this is already the sixth generation. It can be used for future archeological relief, but the battery is a problem Although the gecko robot developed, but Dai Zhendong not too satisfied, "such as adsorption force is not enough, the experiment occasionally fall. In the future to do the article in its feet, for it to wander the ceiling." In the structure shape, experts also have to re-transformation, so that the robot is more like a gecko, "such as to twist the body, and the tail of the robot is also just a decoration." said, although no long-tail gecko setae, but the role of a tail of a large, attached to the wall, the greater the contact surface, can also play a supporting role, the equivalent of a gecko's fifth leg. Tail in the future, the robot should also be transformed. "Gecko robot" What future can apply, Dai Zhendong also like a lot. And wheeled robot crawler compared to the "gecko robot" This legged robot has many advantages, because it is very normal walking on uneven ground. "The robot can also be to some people can not reach the harsh environment, Quest archaeological work." Dai Zhendong Imagine, in addition, meet some of the natural disasters, "gecko robot" can fly, move freely, to work for the rescue provide help. Even in space, it also has the ability to display their place in space under zero gravity condition, the robot can also be secure in walking on the surface of some objects, can help mankind to complete some specific task. However, although the outlook is very broad, but to really apply it, there is a big problem, "that is, the robot's energy supply problem." Dai Zhendong explanation, which is currently facing international challenges, if it is installed ordinary lithium battery, use of time is very limited. If installed solar cells,http://sugarless.lovesick.jp/g_adoumei/memo/apeboard_plus.cgi?command=read_message&msgnum=60/, on the one hand require sunlight, on the other hand solar cells need to reach a certain area, installed in a small robots may not be convenient. related news Japan's nuclear crisis Why useless domestic robot Japan is a world leader in robotics,hogan outlet sito ufficiale, but according to the news, after the nuclear crisis triggered by the earthquake in Japan, the Japanese government did not put this domestic robot rescue. Sources also said that Japan and even the German government request to provide remote control robots. This approach has aroused speculation about the outside world and questioned. Nuclear leak site environment unpredictable Yesterday, Instrument Science and Engineering, Southeast University, Dean, Institute of Robotics and sensor control technology Song Aiguo, director of analysis, Japan's strengths are mainly produced intelligent humanoid robot, annual investment of funds is considerable. This robot can sing and dance, expressive, strong ability to imitate people, but robots to replace the current one is impossible. If the case of nuclear accident, the surrounding environment is unpredictable, you need to perform the task the robot is unknown, even humanoid robot to enter the scene, it is impossible to analyze the surrounding environment to understand, to make the appropriate relief. In addition, the level of industrial robots in Japan is the world leader, has played a huge role in industrial production. For example, automobile production process, welding, painting, assembly and other work can be done. But the robot can only perform tasks based on a fixed human instruction, to get this kind of robot to enter the hazardous environment rescue, it is unrealistic. "The Japanese do not use robots and rescue, mainly because there is no specific study of this nuclear emergency robot." He explained. Components of nuclear radiation damage "After the nuclear leak, radioactive material itself can damage components on the robot." Song Aiguo said radioactive material is likely to cause instant failure of the electronic system, the general camera will soon be damaged failure. Meanwhile, due to the impact of high-energy particles, the robot core processing system will be damage, leading off control can not be effectively carried out. In such a hazardous environment, you must use the special remote control robot, which is borrowed from Japan to Germany, this robot. Song Aiguo says, for example, people should be able to far distance outside of the robot remote control, directing them to complete the task, remote control range 1 km even farther away. Moreover, this type of robot itself must be resistant to radiation. Song Aiguo said material is first robot must be resistant to radiation. At the same time, but also a seal of design, resistance to washing, it is because the use of the robot must be cleaned. In addition, the camera has to be a special, radiation-resistant.
