The research and development of bionic machinery can be traced back to the 1950s. After decades of development, bionic machinery integrates many technologies, such as computer technology, sensor technology, control technology and so on.

Today, the development of intelligent industry has opened a bigger door for human imagination, but also put forward new requirements for bionic machinery. We need more sophisticated bionic machines to accomplish more difficult tasks, help us improve our existing production and life, and help us explore the mysteries we have been curious about for a long time.

Robot butterflies that can work in groups Festo of Germany has developed a robotic butterfly with a wingspan of up to 50 centimeters and weighs only 40 grams. Its ultra-light wings have a "skeleton" made of carbon rods and a layer of blue elastic film. The Butterfly's fuselage, which includes a battery and two small motors, can fly for four minutes at full charge.

During the Butterfly flight, the infrared camera detects the small light-emitting diode (LED) on the fuselage and records its position information. After analyzing this information, the computer can adjust the flight path for each "butterfly" in real time, and even make robotic butterflies fly in flocks without colliding with each other.

"Nature tells us that even animals that are neither strong nor particularly complex can exhibit coordinated movement as a group," said Dr. Heinrich Frenzek of Festor. "and it doesn't require much complex programming, just a few simple rules to avoid collisions."

Fisto said that robotic butterflies could be used in factory monitoring systems in the future.

A team of researchers at the University of Washington has developed a miniature sensor that does not need a battery (using solar energy)-by imitating the way dandelions sow seeds. The sensor can be spread in all directions with the help of wind. This sensor can be used for different purposes and in different environments to obtain temperature, humidity, precipitation, light intensity and other environmental data. With this sensor, researchers do not have to travel around, but are replaced by sensors to travel mountains and rivers, so that they can easily obtain detection data.

"the reason why dandelion seeds can float in the wind is that the seeds are covered with fluff, which increases the air resistance and slows down the falling speed of the seeds. According to the two-dimensional projection of dandelion seeds, we designed the structure of the sensor." Vikram Iyer, an assistant professor at the University of Washington and a core member of the research team, said, "however, as more and more components are installed on the sensor, the 'fluff' around the sensor starts to bend inward, slowing down much less. In order to solve this problem, we add a ring structure to the periphery of the sensor 'fluff' to make it not easy to bend, thus expanding the contact area between the sensor and the air and slowing down the falling speed. "

The weight of each dandelion structure is about 30 milligrams. It sounds light, but it's 30 times the weight of dandelion seeds. But don't worry, even in a gentle breeze, the sensor can still float for about 100 meters. Each such structure can carry at least four sensors, and after landing, the sensor can still transmit data to a radius of 60 meters.

A dandelion robot that can pollinate plants scientists at the University of Tampere in Finland have developed a miniature robot that can pollinate plants. The robot, called Fairy, weighs just 1.2mg and can fly with the wind.

The structural design of "Fairy" draws lessons from the shape of dandelion seeds, and through lighting, the user can control the opening and closing of the robot's "fluff" to change its shape, making it easy for the user to adjust the robot's flight trajectory in the air.

Scientists at the University of Tampere say they plan to release millions of "fairy" robots carrying pollen and fly them to plants that need pollination through light guidance.
