What did scientists learn from what insects and what did they invent?

Because bats emit ultrasonic waves when they fly, they can detect the ultrasonic waves reflected back from obstacles. Based on this, scientists have designed a modern radar - a radiolocation and ranging device.

Scientists have invented artificial dolphin skins that can increase torpedo speed through the study of dolphins' low swimming resistance; and wheelless cars (jumping machines) that imitate the form of kangaroo movement in the desert, etc.

Inspired by penguins, scientists from the Institute of Zoology of the Academy of Sciences of the USSR have designed a new type of car, the Penguin, a polar off-road vehicle. The wide bottom of the car, which is directly attached to the snow, is propped forward by wheels and spoons, and can travel at speeds of up to 50 km/h.

Scientists have built space robots in imitation of insects.

A team of researchers at the Australian National University has developed a small navigation and flight control device through the study of several insects. Such a device could be used to equip a small vehicle for Mars exploration.

Inspired by biomimicry, British scientists are developing a submarine that can swing its tail fin to "swim" in an S-shape, and the main innovation of the new submarine is the use of a device called an "elephant trunk actuator". The "trunk" consists of a set of hoses made of thin, soft material that mimics muscle activity and pushes the movement of the fins. The new submarine can be used as an underwater minesweeper to deal with mines that can detonate at the slightest noise or interference. 2

In "Bats and Radar", people get a lot of inspiration from animals and what else they invented.

1. By observing the thorns of thatch, Lu Ban was inspired by thatch, and invented a saw that was sharper than thatched grass;

2. Newton discovered gravity by an apple falling to the ground;

3. Watt observes the water vapor in the pot coming out, and pushes the lid of the pot to beat to invent the steam engine;

4. Edison discovered that the diaphragm in the microphone would cause vibration with the sound of speaking, so he took a short needle and experimented with it, from which he got a great inspiration and invented the phonograph.

1. Scientists imitated the structure and function of jellyfish ears and designed the jellyfish ear storm instrument, which accurately simulated the organs of jellyfish to feel infrasound waves.

2. The eggshell is arched, with a large span, including many mechanical principles, although it is only 2 mm thick, it is difficult to destroy it by smashing it with a hammer, and architects imitate it for a thin shell architectural design.

3. Colorful butterflies are brocade in color, such as heavy moon pattern butterfly, brown golden spotted butterfly, etc., especially the fluorescent winged butterfly, its hind wings are sometimes golden in the sun, sometimes emerald green, sometimes from purple to blue, scientists through the study of butterfly color, for the military defense has brought great benefits.

4. The dragonfly vibrates through its wings to produce a locally unstable Mingwei airflow that is different from the surrounding atmosphere, and the well uses the vortex generated by the airflow to make itself rise. The Dragonfly can soar with very little thrust and can fly not only forward, but also backward and left and right, and can fly forward at speeds of up to 72 km/h. In addition, the dragonfly's flight behavior is simple, relying on only two pairs of wings to flap constantly, and the scientists of the science and technology have successfully developed the helicopter based on this structure.

5. Entomologists have found that the hind wings of the fly degenerate into a pair of balance rods, when it flies, the balance rods vibrate mechanically at a certain frequency, which can adjust the direction of movement of the wings, and is a navigator to maintain the balance of the fly's body.
