The invention of mankind-inspired by animals-ships and submarines came from people's imitation of fish and dolphins. Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose. The rocket takes off by using the recoil principle of jellyfish and squid. Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability. Scientists studied frog eyes and invented electronic frog eyes. The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes. Humans also used the principle of leapfrog to design a toad ram (hang). Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation. Bionic and high-tech modern radar-a radio positioning and ranging device: Scientists have found that bats rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bats emit ultrasonic waves when flying, they can also detect ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device. By studying the tiny swimming resistance of dolphins, scientists invented an artificial dolphin skin that can improve the speed of torpedoes. And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert. Inspired by penguins, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-Penguin brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface, supported by a wheel spoon, and the speed can reach 50 km/h. Scientists make space robots by imitating insects. A research team of Australian National University has developed a small navigation and flight control device by studying several insects. This device can be used to equip small aircraft for Mars exploration. Inspired by bionics, British scientists are developing a new submarine, which can swim in an S shape by swinging its tail fin. The main innovation is the use of a device called "trunk actuator". "Elephant trunk" consists of a group of thin and soft hoses, which imitate muscle activity and promote fin movement. This new submarine can be used as an underwater mine-clearing submarine to deal with mines that will detonate at the slightest sound or interference. A teacher invented a hexagonal desk. Students praised it as "endless fun". Chen Dong Farming, a young teacher in Ningbo, has a new desk with a hexagonal desktop, replacing the traditional rectangular desk that has been used for a long time in the teaching circle. Chen Dong said in an interview that the idea of designing this new desk was inspired by bionics theory. In nature, the hexagonal honeycomb structure is unique, and the hexagonal snowflakes have different shapes ... After the desktop of the desk is transformed into a hexagon, the combination is flexible, the appearance is pleasing to the eye, the limited space can be effectively used, and the classroom atmosphere is active, which is welcomed by students. Now all classes in Zhicheng school and primary school are fully promoting the use of hexagonal desks. Japanese scientists were inspired by ants foraging. They developed a large-scale integrated circuit, simulating foraging ant Qi Xin to carry food together, and continuously transmitting information from the nearest "food source" to the "ant nest". According to this new information processing method, it is possible for people to develop a computer with a new computing mode.
There are still many inspirations from nature, such as: imitating the characteristics of egg shape and building arch bridges; Inspired by the flight of birds, people invented airplanes. I cut off my fingers from the thatch and invented the saw ... There are many animals and plants in nature, which hint at the mysteries of nature in their own unique way of life.
Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, and wells use the vortex generated by the airflow to lift themselves up. Dragonflies can soar under a small thrust, not only forward, but also backward and left and right, and the forward flight speed can reach 72 km/h. In addition, the flight behavior of dragonflies is relatively simple, with only two pairs of wings constantly flapping. Scientists have successfully developed a helicopter based on this structure. When an airplane flies at high speed, it often causes violent vibration, and sometimes even breaks the wing, resulting in the plane crashing. Dragonflies are safe when flying at high speed, so people follow the example of dragonflies and add counterweights to the wings of aircraft to solve the thorny problem of vibration caused by high-speed flight.
Fish have the ability to come and go freely in the water, so people imitate the shape of fish to build ships and use wooden paddles to imitate fins. According to legend, as early as the Dayu period, the working people in ancient China observed fish swimming and turning with their tails wagging in the water, so they put wooden paddles on the stern. Through repeated observation, imitation and practice, it was gradually changed to paddle rudder, which increased the power of the ship and mastered the means of capsizing. In this way, even in the rolling river, people can let ships sail freely.
