The best answer is to report on human inventions-boats and submarines inspired by animals come 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 found that bat monsters rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bat magic emits ultrasonic waves when flying, it can also detect the ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device ... Scientists have invented an artificial dolphin skin that can improve the speed of torpedoes by studying the tiny swimming resistance of dolphins; And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert.

Inspired by King Penguin, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-"King Penguin" brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface and supported by a wheel spoon, and the driving 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 under the slightest noise or interference. In ancient times, lightning burned the forest. The ancients found that food after fire is more delicious than raw food, and fire can keep warm. When two stones collide, there will be sparks, so they learned to make a fire. The ancient people found that plants could grow when seeds fell into the ground, so they learned to farm. ..... Birds have wings to fly, so they invented airplanes; ......

The survival of human beings depends on nature, and the development of human beings is based on the revelation of nature. Without the revelation of nature, there would be no such developed civilization as human beings now!

Luban used lotus leaves as umbrellas; The electronic frog eye is invented according to the frog eye; The ship was invented according to the "streamline" of the whale body; According to birds, airplanes were invented; A bionic photolysis device was invented according to cyanobacteria. The jellyfish ear storm detector was invented according to the jellyfish ear; Velcro was invented according to Xanthium sibiricum. Sonar is invented according to the positioning system of dolphins ~

2. According to the structure of the Bird's Nest, the main stadium tube (named Bird's Nest) of Beijing 2008 Olympic Games was built.

According to the inspiration of the chameleon's escape, people invented special military uniforms for different geographical environments.
