Chapter 73 (1/2)
The next day.
Zhang Wei arrived at the company less than 7:30. At this time, most of the company's employees are still sleeping in. In fact, this is also a very normal thing. Zhang Wei is working hard to realize his dream. His heart is naturally full of passion and motivation.
After arriving at the company, Zhang Wei went directly to the experimental building. He had already explained to his secretary and Liu Hai. He would concentrate on researching new products in the next time. The company's affairs were fully handled by Liu Hai and other leaders without reporting to him. Of course, there is a regular meeting every week. After all, he is the boss of the company, so he can't know nothing about the situation of the company.
After arriving at the experimental building, Zhang Wei said hello to Beidou, ”good morning, Beidou.”
He has been with Beidou for such a long time, and his attitude towards Beidou has gradually changed. In his mind, Beidou is no longer a cold program code, but a friend and right-hand man.
He has also been used to Beidou's existence. He even chats with Beidou frequently. When Beidou is around, he will not feel lonely any more.
”So do you, sir.”
Beidou replied immediately.
Zhang Wei smiled and told Beidou to remind him to go home for dinner at seven o'clock in the evening, make himself a cup of hot tea, and then began to concentrate on the research of intelligent robot technology.
According to the work plan he made yesterday, the first step is to complete the structural design and motion control system of the robot. In his vision, as like as two peas,
is not only a simple man but also a human being.
For example, it is a great challenge for humanoid robots to walk as smoothly as humans without falling.
Taking the humanoid robot Ao < of Honda as an example, engineers have done a lot of work just to prevent it from losing its balance and falling down in the process of walking.
First of all, engineers spent a lot of time in the initial stage of the project studying the leg movement of insects, mammals, and even the leg movement of mountaineers when climbing mountains. These studies help engineers better understand what happens when we walk, especially the movement of joints. For example, when we walk, we move our center of gravity and swing our hands back and forth to balance our body. These constitute the basic way of Ao walking.
In addition, in the process of walking, our toes also play a very important role in balancing our body. There is a similar mechanism in Ao's feet, and shock absorbing materials are also used to absorb the impact of walking on joints, just like human soft tissues.
Secondly, engineers designed three control systems.
Ground reaction force control: the sole of the foot should be able to adapt to the uneven ground and be able to stand stably at the same time.
When the target Zo can't stand and starts to fall, he needs to control his upper limb's reverse movement to control the upcoming wrestling, and at the same time, he needs to speed up his pace to balance his body.
Foothold control: when the target Zo needs to adjust the spacing of each step to meet the relationship between body position, speed and step size at that time.
