“Another example is the tail of an intelligent bionic robot dog, which seems to be an unimportant or even neglected part, but encountered difficulties during the development process.
"The dog's tail is an extension of the body's spine. Compared with the semi-active spine, the dog's tail is very flexible and can move up, down, left, and right, either slowly or quickly.
"The tail is not just a decoration, but a part with actual functions. Therefore, during the development process, the primary issue is how to design a continuous joint structure so that it can move flexibly. In normal times, the tail can be used to express emotions and exercise.
Keep your body balanced by swinging from side to side.
"Therefore, we not only need to design a continuous joint motion structure for the tail, but also need to equip it with a complete motion system so that the robot dog can flexibly control the entire tail."
"In addition, there is a very important issue, that is, how to minimize the impact of the dog's tail on the robot dog and avoid it becoming a weakness of the entire robot dog.
"A dog's tail is easily injured, which is why many dog owners like to cut off their dog's tail to avoid fractures or being bitten by opponents when fighting with wild beasts or other dogs.
"The tail of a robot dog can be a tool for expressing emotions and controlling body movements, but it should not be the only tool. The existence of the tail can help the dog maintain balance when moving at high speed, but even without a tail, it will not affect the robot dog.
running ability.
“For most pet dogs, this may not be that important because they live in a relatively safe environment and do not encounter many unexpected situations. However, for many working dogs, the situation is different.
They often need to perform dangerous tasks, so they cannot have weaknesses in this area, let alone let their tails become a handle used by the enemy to restrict these robot dogs.
"We have put so much effort into developing this intelligent bionic robot dog, not only to make it a pet toy for everyone, but also to make it take on more tasks and be used in various fields."
After listening to Wu Hao's narration, everyone couldn't help but nodded. Indeed, if it was just a toy, then it would not be worth investing so much energy, and Wu Hao's emphatically preaching at the press conference would be meaningless.
So in what fields can this intelligent bionic robot dog be used? Different people have different interpretations of this.
"In addition to the entire movement system, we also require this intelligent bionic robot dog to have a flexible head and powerful biting ability. We know that the dog's main weapon is its mouth and powerful biting ability.
"This function may be dispensable for pet dogs, but it is very important for working dogs. Moreover, the ability of a dog's mouth to open and close also has other functions in daily life, such as biting objects, roaring to eat, etc.
"In the intelligent bionic robot dog, although there is no need to rely on the dog's mouth to eat, nor does it need to use the dog's mouth to open its mouth to make sounds to roar, but we need it to have the ability to bite, whether it is applied to pet dogs or in the working environment.
"It seems that the mobility of a dog's mouth is very simple, but in fact it is very difficult to simulate it. First of all, the dog's mouth must be flexible, able to open and close quickly, half-open and half-close, etc. In addition, it must have powerful
Bite force.
"Finally, it is also crucial to control the force of opening and closing the dog's mouth. Be gentle when necessary, be strong when necessary, and be able to control the force of the mouth with ease is very critical."
After saying this, Wu Hao glanced at the people in the audience, paused for a moment, and then said with a smile: "In addition to the entire movement system, we also need to equip this intelligent bionic robot dog with some functions, such as a powerful sense of smell, vision and hearing.
Ability. Only in this way can this intelligent bionic robot dog have the same keen sense of smell, vision and hearing as a real dog.
"The first is visual ability. We have equipped this intelligent bionic robot dog with the most advanced compound eye lens, allowing it to see different spectral images, such as ordinary white light images, infrared thermal imaging images and night vision low-light images. At the same time,
, it can also zoom to observe distant targets and smaller objects.
"Of course, ordinary pet dogs don't need such high-cost compound eye lenses. We only need to equip them with a synthetic hole lens to retain the ability to see white light and night vision in low-light images. The blessing of compound eye lenses allows intelligent bionic robot dogs to be used in
The visual observation ability far exceeds that of a real dog, and it can see many things that dogs cannot see.
"In terms of the auditory system, we equipped it with a very complex sound pickup array, which allows it to hear very weak sounds. Even the sound of two people talking a hundred meters away can be heard clearly. Similarly, ordinary
Pet dogs do not need such powerful sound field monitoring capabilities, and this feature is mainly used for working dogs.
"As for the olfactory system, at present, we are not able to produce an olfactory device product that is small and comparable to a dog's nose. However, we have developed a relatively less sensitive air composition detection device for this robot dog, which
It can analyze the components in the air in real time and generate corresponding reports. This is the only flaw and regret of our intelligent bionic robot dog. Of course, this does not affect ordinary pet dogs, only working dogs.
"In other words, the above powerful functions are not applicable to ordinary consumers, so they have no impact on most people. But for intelligent bionic robot dogs used in various fields, these functions are very important.
Luckily it wasn't fatal."
At this point, Wu Hao looked at the audience, spread his hands and said with a smile: "Okay, now that we have these subsystems, the biggest problem we face is how to integrate them together and assemble them into a complete smart phone."
Bionic robot dog.
"Perhaps many people think this problem is very simple, just install them together. But, what is the difference between the intelligent bionic robot dog assembled in this way and those dog-like four-legged robots?
"Therefore, we need to organically combine these subsystems according to the dog's body physiological structure to form a perfect whole. Maybe you are a little confused, why must we assemble and integrate according to the dog's body physiological structure? The reason is that we are bionics
It's a robot dog, so it naturally needs to be assembled and integrated according to the dog's physical structure.
"Another important reason is that dogs have existed on the earth for more than 50 million years, much earlier than humans. After tens of millions of years of evolution in nature, their physiological structures have adapted to
The natural environment has reached a very perfect level.”
