Scientists have developed ostrich like robot legs, what role will the device play?

The matter of "scientists developing ostrich-like robot legs" has recently been on Weibo hot search, which has aroused heated discussions among the public. Once again, everyone felt the progress of science and technology.

Inspired by insects, scientists have developed semi-soft "flexible skeleton" robots, and using this technology, scientists have developed a fully automated assembly line for manufacturing the entire one"In groups"These robots will work together to complete tasks such as searching for survivors at the disaster site. And now, scientists have learned from the teacher of nature and invented the ostrich leg.

Following the example of bird legs, scientists invented the ostrich leg, which is thought to be responsible for its excellent athletic performance. Unlike humans, birds fold their feet back when they pull their legs towards their bodies. This foot movement pattern is energy-efficient for both walking and running, and the bird's leg structure and all its bones, muscles, and tendons, scientists transferred them to a walking robot.

1. Transportation industry

Ostrich legs are used as an efficient, fast, energy-saving, and convenient tool. It can be applied to the transportation of materials, for remote mountainous areas, which also saves labor costs, reduces the number of people walking and transportation, and makes their work easier. Compared with the car, the ostrich leg can walk on the environmental requirements is not high, can cross the forest for material transportation, so as to save more time, cost and energy transportation, reduce the transportation cost not only to reduce the burden of the enterprise state, but also to reduce the burden of the environment.

2. First aid industry

In urban life, there are often blood, organs, etc. in the process of emergency transportation traffic jams, resulting in the loss of the patient's life, with ostrich legs, you can let the ostrich legs take the small road, sidewalk when the traffic jam can not go to various ambulances. Save more time. In addition, ostrich legs can be used to form a simple ambulance, which can send emergency patients to the hospital as soon as possible.

3. Prosthetic improvement

For people with disabilities who have lost their legs, the ostrich legs can be changed to resemble human legs, as well as speed. Help those who can't get up back on their feet and help them walk again.

Using similar principles and engineering bionic technology to the physiological excitation and movement laws of ostrich, three bionic mechanical legs were designed, and experiments proved that the leg construction of bipedal ostrich-like robot can save energy and reduce vibration, and the comprehensive performance is the best. The bionic robotic leg realizes the tendon-bone interaction, the extremely simplified muscular interaction mechanism and the bionic design of the three pubic bones sequentially off the ground.

The effect is to be able to go farther and run faster. It can be truly used in drones, robots, the future express delivery industry, and the fire industry, and can walk like a bird.

Energy saving, running faster, more agile, powerful, fast and so on, and this equipment will be vigorously promoted and used.

As an agile robot, Cassie was inspired by ostriches. In addition to commercial application research, Cassie can be used in search and rescue, such as floods, and mining disasters, as well as in medical applications, such as bone replacement and prosthetic assembly. In terms of logistics and distribution, we provide effective transportation and reduce consumption costs from Yuanchang.

In the future, Cassie's research will also improve and develop new features. Increasingly, this behavior will be used in production processes that do not allow the use of wheels, but need to be performed quickly. ”

<> artificial intelligence is adding more anthropomorphic capabilities to robotsWith the advent of the era of artificial intelligence, countries around the world are focusing on artificial intelligence-related industries. China has also introduced a lot of relevant policies, such as service robots as a strategic technology for the priority development of the future. Therefore, the development prospects of artificial intelligence robots are good.

The bipedal robot Cassie successfully completed a 5-kilometer jog, which is not faster than a human in the short term, but it also indicates that the development of artificial intelligence robots will continue to advance. In the future, more and more AI robots will be used to serve people's lives. We think that the design experience of this robot can be applied to more running robots.

Jerry Pratt said:"In this way, these running robots can become more efficient and their movements look more natural. "The behavior of running robots will increasingly be used in manufacturing processes that do not have wheels but need to be performed quickly"。

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, such as Xun Yuguo** There is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

It is possible to apply this technology to specific areas, such as forest fires, **, on-site treatment of nuclear power plant accidents, etc. For example, it is too dangerous, the cost is too high, and the scene that is too far away from the leaky auspicious stare can be used late.

It can be used in the medical industry, construction industry, catering industry, service industry, sports industry, technology industry, and other fields.

It is used in medicine, construction, petroleum, new energy, toys and other fields, because these fields have a large demand for it.

If the leg structure of the Tyrannosaurus rex, which lived 66 million years ago, is similar to that of the ostriches that run on the grasslands today, then we can assume that the legs of birds have stood the test of time – a good example of evolutionary selection.

<> grace, grace, power - a flightless bird like an ostrich is a mechanical marvel. Ostriches, some weighing more than 100 kilograms, travel through the steppes at a speed of 55 kilometers per hour. The ostriche's excellent athletic performance is thought to be due to the animal's leg structure.

Unlike humans, birds fold their feet back when they pull their legs towards their bodies. Why do animals do this? Why is this foot movement mode energy-efficient for walking and running?

Can a bird's leg structure and all their bones, muscles, and tendons be transferred to a walking robot?

The robot looks like a miniature ostrich. According to Jerry Pratt, a senior research scientist at IHMC, the ostrich is designed with oval wheels that allow the other leg to exert more force when it feels resistance. The flat elliptical wheels are driven by a single motor, which significantly reduces power consumption.

The ostrich makes a physical elliptical movement on its legs, which provides stability to the ostrich's body shape. An ostrich can run at speeds of up to 10 miles per hour, but if the robot is the size of an adult, it will reach speeds of 20 to 30 miles per hour.

Recently, scientists from the Max Planck Institute for Intelligent Systems in Germany were inspired by the ostrich leg to develop a robot leg that uses fewer motors than other types of robot legs, is more energy-efficient, and is fast, agile and powerful.

This ostrich-like robot leg has the advantages of energy saving, fast, environmental protection, strong and powerful, durable, and elegant.

It is more energy-saving, very fast, powerful, can be more agile, and can be used better.

Nature is not only magical, but also a good teacher, and many of our human inventions are derived from nature. Scientists have created an imitation ostrich robot leg through the study of ostrich running, which has the advantages of energy saving, fast, agile and powerful compared with ordinary robot legs, which has greatly promoted the development of the robot industry.

Ostriches are one of the animals that exist in nature, and although they are birds, they cannot fly. Even if you weigh more than 100 kilograms, you can run at a speed of 55 kilometers per hour. The ostrich runs gracefully and endurically, and with its excellent running speed, it dodges attacks from predators.

For a long time, the leg structure of ordinary robots needs to consume a lot of energy, which has a great impact on the long-term work of robots. Careful scientists, through the study of ostrich running, found a way to improve, compared with ordinary robot legs, ostrich robot legs have the following two advantages.

Ordinary robots need two motors for their legs, one for walking and the other for bending their knees; This setup adds to the robot's structure, making it more complex and much heavier.

Compared with ordinary robots, the ostrich robot has one less motor, which imitates the principle of ostrich walking and running, saves a motor, and also makes the leg structure simpler, and it will be more energy-saving and efficient during use.

Ordinary robots are not as flexible as human legs when walking, and it is impossible to achieve uniform strength coordination. In the process of use, in addition to consuming energy, the robot will bring us a worse experience.

Such a situation can be reflected in the legs of the ostrich robot. The ostrich robot legs, drawing on the advantages of the ostrich legs, combine the advantages of speed, agility and power, which can also save energy and make the robot work longer.

With the development of science and technology, the robot industry will also get better and better. By combining robots and artificial intelligence, one day they will be able to completely replace humans and do some hard and dangerous things.

Different from ordinary robot legs: the agility and running speed of the ostrich are very fast, which effectively improves the work efficiency of the robot; The coupling mechanics are achieved in the robot legs and feet, resulting in energy-efficient and robust robot walking; Zero effort when standing, as well as when bending legs and knees.

Scientists have developed ostrich-like robot legs that use fewer motors than other types of robot legs, are more energy-efficient, and are fast, agile, and powerful. It is reported that this newly developed robot legs force other types of more energy-efficient, fast, agile and powerful.

More sensitive, more recognized. So, such robots are great and make people especially like.

First of all, the legs are very slender and they are faster when they run, and then they are able to complete more difficult leaping movements, so the difference is greater.
