Why did the cockroach robot that could not be stepped on become an ideal choice for search and res

Because such a small and durable robot is very advantageous in search and rescue missions, it can reach small corners that are difficult for rescue dogs, rescue personnel, and rescue vehicles to reach, or in high-risk places.

The study was published in the July 31 issue of the journal Science Robotics, according to Science Daily. Liwei Lin, a professor of mechanical engineering at the University of California, Berkeley, who is the researcher, said that most of these small-scale robots are so fragile that if you step on them, you can almost destroy them entirely, so we use elastic and thinnest materials to make them without worrying about being squashed. 」

The report notes that the robot, the size of a postage stamp, is made of thin sheets of piezoelectric material of polyvinylidene fluoride (PVDF), which is so unique that it automatically expands or contracts when a voltage is applied to them. The researchers applied PVDF to a layer of elastic polymer to bend the entire material, and then added a front leg to it, which propelled the robot forward in a jumping fashion as the material bent or straightened under the electric field.

This cockroach robot has some extraordinary abilities, it can move 20 times its body length per second, which is faster than the average cockroach. It is reported that this is currently the fastest insect-level robot, and it can also pass through pipes, climb slopes, and carry small loads, such as peanuts. However, the most impressive thing is that this robot, which weighs less than a gram, can withstand a pressure of about 60 kilograms, which is about the weight of an ordinary person.

Lin Liwei said that the undead cockroach can describe the cockroach's vigorous vitality, and when the researchers stepped on the robot hard, it still continued to function, so in certain situations, its vitality is very similar to that of a cockroach.

Because it imitates the characteristics of cockroaches, it is not dead and has good toughness. And it's not easy to break.

Because this robot mimics the effect of a cockroach.

They are more rugged and can survive in a variety of harsh environments.

It is small in size, but it can go to very harsh environments and can withstand a lot of pressure.

Because it is because of its unlethal performance, it is very reliable and durable.

Small in size, strong in pressure resistance, and can enter small spaces.

The robot can go to places with harsh environments to search and rescue trapped people.

Because this kind of robot has good toughness and is not easy to break.

This cockroach his life is very good and resistant.

They have made breakthroughs in terms of movement speed and compression resistance by developing a new type of soft robot that mimics cockroaches.

It allows you to practice how to step on cockroaches an unlimited number of times, so that when you encounter a real cockroach, you can do it handy and kill with one hit.

Because it is imitating the characteristics of the cockroach and his ability, it is better to go to the internship.

Militarization exercises can be carried out in better concealment.

It is done to mimic the function and performance of cockroaches.

This will ensure that he has better endurance and safety during these tasks.

It is possible to search and rescue people in confined spaces.

It can make the robot faster.

It can make the robot more robust and adapt to a variety of environments.

Silly, hehe, and if you are good, I like the camera, the amount of the first few episodes, the amount of money, the amount of money, the answer, the surprise, the surprise, the

They developed stress resistance by mimicking cockroaches.
