After the meal, Miao Dazhuang asked Yu Miaoxue to familiarize herself with it first, and then get it out on the company's official website, if you don't understand, you can ask him.

Miao Dazhuang came to the private laboratory on the fourth floor, raised his head and looked at the camera above, the glass door automatically opened to both sides, and after entering the interior, the palm of his hand pressed on the door, and the door moved to the right after fingerprint recognition, and the brake closed after entering.

I saw that various mechanical arms were working on their own in the laboratory, and there were also unmanned cars running around with mechanical arms, and a robot that was about to be assembled was lifted in the air by the mechanical arm, which was similar to the appearance of the robot in the Terminator, but there was no painting, and the robot was still carbon and aluminum alloy, and the natural color of plastic.

When the robotic arm twisted the last screw into the screw hole, the robot that was suspended in mid-air was slowly put down, and all the machines stopped working in an instant.

"Brother Miao's robot has been assembled, is it necessary to collect data next?" The voice of the artificial intelligence "Miao Miao" came from the loudspeaker of the laboratory

Miao Dazhuang gave priority to the installation of the laboratory on the fourth floor, and during this time, everything in the laboratory was controlled by artificial intelligence, including the design and manufacturing of robots, which were also completed by artificial intelligence.

Inside the body of the robot there are three lithium batteries, one for the legs and one for the abdomen, free movement and the calculation of the control system of the microcomputer, which is where the most power is consumed. In order for him to continue to be active for longer, three large batteries were necessary. But even if the robot is turned on at full power in this way, it can only be used for a maximum of 4 hours in theory, mainly because the current battery is not good.

Small servo motors and stepper motors are used as drives for each joint, and hydraulic shock absorbers are used for the ankles.

This allows for a more approximate simulation of a human walking upright.

The way of bipedal walking is very unstable, so if the robot wants to walk upright, it must balance the device, and now the built-in balance system in this robot is a set of gyroscopes.

The control system is decentralized. The use of multiple microcomputers to control the robot, the head of the crisis, responsible for system management, communication and kinematic calculations. and the sending of instructions. There is also a corresponding CPU at each joint for control and interpolation. This control reduces the burden on the host microcomputer.

The last sensors include laser sensors, thermal sensors, life sensors, fluid sensors, and sensory organs as robots.

See if it starts. Miao Dazhuang turned on the power, and the laser sensor in the middle of the robot's pupils and chest lit up.

"Yes," Miao Dazhuang breathed a sigh of relief

"Miao Miao, can you connect it? Miao Dazhuang asked.

"Yes." Miao Miao's immature voice sounded.

"Now you control him to stand up and try, you don't do the calculation in the machine, it can't support your calculation, you send the command to him. Let him run it as instructed to control it this way. Miao Dazhuang said.

"Okay." As soon as Miao Miao's voice fell, the robot in the laboratory slowly stood up, and after the robot stood up, Miao Dazhuang glanced at the computer to see if its parameters were normal, and he couldn't help but breathe a sigh of relief again when he found that there was no problem.

"Now move forward."

Click, click, bang! The robot that had just taken a step lost its balance in an instant and fell straight to the ground.

"Is there something wrong with the balance system?" Miao Dazhuang asked.

"Brother Miao, it's not a problem with the balance system, it's because I don't have specific data on human upright walking, so I can't book the direction and strength of walking," Miao Miao said.

"Then what can you do," Miao Dazhuang asked

"To test the movement data of a person's walking, I can imitate his walking style."

Miao Dazhuang went out to the gym and moved two treadmills over, of course, with a manual hydraulic forklift, although Miao Dazhuang himself moved, but the thing is too big and inconvenient, of course, it is labor-saving. I went out and bought some items.

After everything was done, Miao Dazhuang went downstairs and let Yu Miaoxue come to the laboratory.

"Why did you tell me to go to your lab? I haven't gotten it on the official website yet! Yu Miaoxue came to the door of the laboratory and said

"That's not in a hurry, do me a favor first, and it depends on you whether the company has new employees in the future." Miao Dazhuang smiled mysteriously at Yu Miaoxue

“？？ What the hell are you doing, what does the new employee have to do with me, it's inexplicable. Yu Miaoxue looked suspicious

"Come in and you'll know." After speaking, Miao Dazhuang turned around and walked into the laboratory

Yu Miaoxue followed in, and when she saw the robot in the laboratory, she couldn't help but open her mouth wide and was dumbfounded. She never knew that Miao Dazhuang was making a robot, only that he was making a contactless voice assistant. When I saw a robot like in the movie appear in front of me, except that there was no cool paint, how shocking my heart was.

"Is this a robot you made?" Yu Miaoxue reached out and touched the robot's body

"Semi-finished products, there are still a lot of places to debug, so let you help me."

Miao Dazhuang turned on the robot's start button by himself, and the sensors in his eyes and chest immediately glowed red.

"How can I help you?" Yu Miaoxue stared at the robot intently, which made him full of curiosity.

"It hasn't learned to walk yet, I need a person's movement data, so I'm going to ask you to help me, I'm going to collect your movement data, put it in it, and let it move freely.

"Okay...... Yu Miaoxue nodded, "How to try?" ”

"Change into a sports vest first." Miao Dazhuang handed the clothes he had just bought to Yu Miaoxue.

"So you just went out to buy this." Yu Miaoxue took the bag in Miao Dazhuang's hand and gave him a strange look.

"You turn around first," Yu Miaoxue said shyly

Miao Dazhuang turned around and waited for Yu Miaoxue to change her clothes before turning around and seeing Yu Miaoxue at this time, wearing a high ponytail, wearing a sports vest and sports shorts. The long straight beautiful legs and the flawless body of proportions are displayed in front of him, youthful, full of vitality, and completely devoid of the usual gentle appearance. stunned Miao Dazhuang for a while

"It's beautiful." Miao Dazhuang touched his chin and admired.

Seeing Miao Dazhuang's aggressive gaze. Yu Miaoxue's eyes were shy, her face was flushed, and she was very cute

"Don't look at it, test." Yu Miaoxue was a little overwhelmed by Miao Dazhuang's look, "If you don't test it, I'll go back to work." Yu Miaoxue didn't dare to look directly at Miao Dazhuang's gaze, and her heartbeat began to accelerate.

"Okay, test." Miao Dazhuang said with a smile

Miao Dazhuang grabbed Yu Miaoxue and took out all the human motion testing equipment, which were mainly sensors and optical scanners.

The movement of the human body is composed of more than 200 joints, which can complete highly complex movements, and these movements have a high degree of coordination.

In terms of robot design and intelligent control, human movement is a research hotspot.

Miao Dazhuang gave Yu Miaoxue the sensor headband, and then attached the sensors to his various joints and let him stand on the treadmill. Carrying the robot in the lab onto another treadmill, Miao Dazhuang turned on the data connection of the sensor.

"Now you're ready to collect data, are you ready?" Miao Dazhuang said

"Alright." Yu Miaoxue nodded

"Now take a few steps and try." After pressing the start button, Miao Dazhuang's eyes were on the computer screen.

As soon as his words fell, Yu Miaoxue walked slowly on the treadmill. The data on the computer began to appear and stretch continuously.

"Stop." Miao Dazhuang stopped Yu Miaoxue and looked at the computer screen, "I'll send your walking data to the robot now." ”

After completing the data sending, the robot not far from Yu Miaoxue began to walk. Miao Dazhuang was beside the robot, carefully observing, the distance of its steps was about the same as that of Miaoxue, but there was still a mechanical movement, and the limbs were just stiff movements, and there was no real coordination.

Relatively speaking, it's a lot better than the beginning, because it's just the beginning, and it's very good to have this kind of results.

"Yu Miaoxue, you keep walking, and I will synchronize your data to the robot." Miao Dazhuang returned to the computer and switched to syncing data.

The moment Yu Miaoxue walked, the robot on the other treadmill also walked up, and even the movements of turning their heads were the same. Yu Miaoxue, who watched it, looked surprised.

"Pick up the pace." Miao Dazhuang looked at the movement of the robot and said.

The robot is equipped with a set of gyroscopes, which can automatically adjust the balance, and Miao Miao can automatically learn to adjust. Constantly coordinating the movements of the body, soon, the limbs of the robot began to become natural, and the movements were much smoother.

"Keep up the good work and run slowly." Miao Dazhuang stared at the data on the computer screen.

Hearing Miao Dazhuang's words, Yu Miaoxue also sped up and jogged on the treadmill.

Compared with letting Miao Miao simulate walking by herself and using human movement data to imitate, this method can make the robot's movements more coordinated and closer to humans.

Thirty minutes later, Yu Miaoxue stopped tiredly and looked at Miao Dazhuang breathlessly.

"Take a break." Miao Dazhuang helped Yu Miaoxue wipe her sweat, handed her the water, and then looked at the robot: "The preliminary movement data has been collected, you can take a break and come to see the results of your hard work today." ”
