Military Technology

"After making up our minds, how to develop this robot dog becomes the key. After repeated discussions, we believe that we can mainly proceed from two aspects, one is the hardware aspect, that is, to create a machine with excellent performance in all aspects dog body.

This seems easy. After all, there are so many so-called robot dog technology products, we can learn from them and develop one.

But in fact, those so-called robot dog technologies and products have something to learn from, but there are very few. The robot dogs currently on the market can only be called dog-like quadruped robots, or even quadruped robots. It seems that they have no direct relationship with dogs.

So in this way, we have to start from scratch and design a real robot dog, not a quadruped robot. "

After Wu Hao’s words fell, various videos and photos of dogs were displayed in the air. Wu Hao smiled and pushed away a photo bubble that appeared in front of him, and then continued to speak to the audience.

"We know that there are many types of dogs, big, small, medium. Long-haired, short-haired, and curly. Long-legged, short-legged, and bow-legged.

However, when we remove the dog hair of these dogs, we can see that almost all dogs are basically the same in terms of body shape. It's just that due to the difference in size and breed, these dogs have different sizes, fat and thin bodies, and some differences in length.

From this, we can get a standard dog body structure model, and then we need to design the body of the robot dog based on this model.

It must have a head, a mouth that can open and tear, keen glasses, a nose with a keen sense of smell, ears with a keen sense of hearing, a flexible neck, a strong body, light and powerful limbs, and a body that can Keeping the tail in balance can also express emotions. "

Hahaha…

Hearing Wu Hao's words, everyone in the audience burst into laughter.

Indeed, there are many functions of a dog's tail, but there is one function that is recognized by everyone, that is, it can express the dog's emotions. In different emotions of the dog, the dog's tail also has different reactions, such as happy, angry, vigilant, sad and so on.

Of course, the most important function of the dog's tail is to keep the dog's body balanced during high-speed running. Nowadays, many pet dogs have their tails cut off, which also makes these dogs unstable when running at high speed, and they are prone to falling and wrestling.

After everyone's laughter faded away, Wu Hao continued to speak with a smile: "We can see that these dog-like quadruped robots we have seen before, although they can walk and run fast, they walk very awkwardly. Their quadrupeds don't feel light when they move, as if they are constantly beating the ground, they vibrate a lot and make a lot of noise.

So how to make the robot dog we developed more flexible, light, fast, stable, and powerful. Adopting the quadruped motion structure of the dog-like quadruped robot is definitely not applicable, which means that we will redesign the new robot dog limb motion system.

First of all, we need to understand the physiological structure of the dog's limbs. In fact, like all quadrupeds, it is divided into forefoot and hindfoot, or front paw and hind paw, and can be divided into left paw and right paw according to left and right.

Dog legs are divided into upper arm and thigh, elbow joint and knee joint, forearm and calf, wrist joint and ankle joint from top to bottom, and then there are dog paws, which can also be divided into palms and fingers.

For those dog-like quadruped robots on the market, their limbs actually have only two structures, namely the upper arm (thigh), the elbow joint (knee joint), the forearm (calf), and the lack of wrist joints and dog claws. , the structure is much simpler.

Therefore, this also leads to the relatively poor buffering ability of these dog-like quadruped robots on the market, and the body is unstable when exercising. In addition, there is no dog claw to adapt to the ground, which also leads to these dog-like quadruped robots. The ability to adapt is relatively poor. In addition, the ability to catch will also be relatively poor. "

Speaking of this, the dog anatomy map in the air began to run in place in the air.

"Besides, we can see from the demo picture that when a dog is running, its limbs, including the whole body and its tail, are moving in coordination. When running, the dog's body will shift slightly to the left and right, keeping the body The center of gravity is stable. In addition, the tail also plays a very important role in balancing when running.

As for the traditional dog-like quadruped robots, they only move their limbs, and use the limbs to control the center of gravity of the body and maintain stability. There is no tail, so it is less stable when running at high speed.

In addition, the torso of this kind of dog-like quadruped robot is an overall rigid structure, which also leads to a relatively stiff torso in the running state, so this kind of dog-like quadruped robot cannot achieve the four-legged robot when running. The body remains aligned and maintains the balance of the body. "

"So, we want to design a robot dog that conforms to the physical structure of a dog and has a flexible body like a dog. This is not blind simulation and imitation. The purpose of our bionics is not to make it like a dog, but to It is to give it the excellent athletic ability of a dog.

There is an essential difference between the two. The former is superficial, just a dog-like toy or puppet. As for the latter, it is a robot with the excellent athletic ability of a dog, but it looks like a dog. "

Speaking of this, Wu Hao waved his hands, and the floating images in the air changed, and then he said to everyone in the audience: "As you all know, we have made some small achievements in the field of intelligent bionic robots."

Hearing Wu Hao's words, everyone in the audience at UU Reading www.uukanshu.com laughed lightly. Is this a small achievement? According to you, what is a big achievement? Mr. Wu, it's okay for us to be modest, but don't be too modest, otherwise it will become pride in disguise.

Therefore, in the development process of this intelligent bionic robot dog, we have used a lot of our very mature technologies, but there are also many that cannot be used directly, because we have higher performance requirements for this intelligent bionic robot dog.

For example, this intelligent bionic robot dog is equipped with a new generation of dynamic joint system. It not only operates flexibly, but can burst out powerful force instantly, and requires ultra-high control and operation precision.

In addition, the new generation of dynamic joint system also requires ultra-high pressure resistance and ultra-long working life, which can maintain its long-term operation and low failure rate.

It is even required that the new-generation dynamic joint system should be kept quiet during operation, and the noise should be controlled to less than 20 decibels, or even lower, so as to ensure that the robot dog equipped with the new-generation motion discipline system remains quiet during the action. One point is very important.
