The ups and downs of life in the Siheyuan

The colonel stepped forward and stroked the robot dog's back with his hand.

Seeing the telescopic handle on the back, he lifted it hard and said, "Yeah! It's almost 30 kilograms."

Li Yuan gave him a thumbs up and said, "Awesome, the total weight is 28.5 kilograms."

He put down the robot dog and extended his right hand to Li Yuan, "Zhou Zhisheng, serving in the Science and Technology Commission, nice to meet you."

In May 1982, with the approval of superiors, the National Defense Science and Technology Commission, the National Defense Industry Office and the Science and Technology Equipment Commission were merged into the China National Defense Science, Technology and Industry Commission.

Centralized and unified leadership has been achieved for national defense scientific research and production.

A decision was made on April 1998, 4: the National Defense Science, Technology and Industry Commission, the Equipment Department of the General Staff Headquarters, and the relevant units of the General Logistics Department were merged to form the General Equipment Department.

Zhou Zhisheng is in his 40s and looks very energetic.

"Li Yuan, head of the Yuan Universe Laboratory."

"Okay, don't be sour! Let him run quickly."

"Don't worry, let me introduce you to its characteristics first:

It weighs 28.5 kilograms and can bear a maximum load of 35 kilograms;

Maximum running speed, 25 km/h;

Maximum battery life, 4 hours, using lithium-ion battery;

It can move freely in a small area and can act as an early warning;

Through StarLight communication, it can be manually controlled to complete set tasks and automatically avoid danger when it senses danger.

With this handheld tablet, you can share its vision.

This vision consists of cameras, ultrasonic sensors, laser probes and microwave radar.

On the plains, it can be controlled by the Red Arrow 1 in the air."

"Hiss", everyone took a breath of air.

"After you have used it for a while, you can use it in actual combat!"

Mr. Chu also squatted down and stroked the robot dog in front of him with his right hand.

"Mr. Chu, do you want to give it a try?"

Li Yuan handed the controller to Mr. Chu, while Zhou Zhisheng was staring at the controller without blinking.

In Zhou Zhisheng's mind, there were already multiple scenes of using controllers to direct battles.

It consists of a game controller held by both hands and an LCD tablet.

When held with both hands, there is a rocker on each hand and a button on the index finger.

There is a multi-function button on the index finger of the left hand and a jump button on the index finger of the right hand.

The left joystick controls direction, and the right joystick controls speed.

The size of the LCD panel is only 6*8cm, but it is enough for monitoring.

In order to reduce power consumption, the Wukong second generation series microprocessor WK821 is used.

Its main frequency is as high as 200MH, it integrates RAM and FLASH internally, and can expand the asynchronous parallel port bus.

For ease of use and portability, the battery capacity is reduced and the continuous working time is less than 30 minutes.

However, the removable battery compartment structure allows the battery to be replaced.

As long as the replacement is completed within 30 seconds, the built-in storable battery can ensure the normal operation of the tablet.

After simple training, battery replacement can be completed within 3 seconds.

Li Yuan gave a simple demonstration and Mr. Chu was able to control the movement of the robot dog freely.

The reason why it is so easy is mainly because the control unit inside the robot dog is quite powerful.

The automatic obstacle avoidance of a robot dog is already its basic action.

When moving forward, take actions such as stepping over, around or jumping over obstacles.

At the same time, security tasks are carried out in designated areas.

All of the above are the functions of some of the artificial intelligence codes of Nuwa 1.

Such silky control greatly increased Chu Lao's interest, and he kept trying various control movements.

For example, thrusting, jumping, and moving sideways. With the assistance of artificial intelligence, all actions are completed extremely smoothly.

He played for more than ten minutes and handed the remote control to Zhou Zhisheng, who was eager to see it.

At this time, Representative Tong was not polite and started playing with Colonel Zhou.

Mr. Chu walked to the workbench, pulled out a stool, and sat down heavily.

"I'm old. I'll get tired if I stand for a while." He knocked on his back and looked at Li Yuan.

This is the easiest machine to control I have ever seen. Its control feeling is very close to the control method of Red Arrow 1.

Any tips? "

“In fact, the source code was available when the Red Arrow 1 flight control system was handed over, but that part of the code was specially encrypted and only a few people could access it.

You are the chief officer, so you probably didn’t pay attention.”

"I definitely can't understand the code you wrote. How would I know if you didn't tell me?"

"Hehe", Li Yuan did not force himself to defend himself.

"Don't be pretentious, tell me quickly?"

"Actually, it's nothing. We just add some special codes and use the neural network algorithm..." Li Yuan looked at Mr. Chu's confused eyes and stopped.

"Go on. Although I don't understand it, it sounds so advanced." Mr. Chu rubbed his temples with his hands and kept muttering in his heart.

"Okay, let me put it another way.

That is, when you press the forward joystick, this code will make some appropriate adjustments based on the posture of the robot dog and the scenery in front.

For example, based on speed, it will calculate the braking distance in real time, and set a warning point based on the road conditions ahead. Before this warning point, it will immediately convert to speed based on your joystick output.

When approaching the warning point, it will correct the speed, which is actually slowing down.

If you don't slow down, it will make leaps, jumps, sideways movements, etc. based on the road conditions.

All these actions are completed by five high-performance CPUs in the robot dog's body."

Each of these five CPUs has its own division of labor and is responsible for posture, video, communication, comprehensive control and auxiliary functions.

Attitude control CPU: Based on multiple sensor information, the adjustment parameters are quickly calculated and transferred to the comprehensive control CPU through a high-speed bus.

Video CPU: accepts video information, compresses it, and transmits the video information to the communication CPU. At the same time, it forms three-dimensional horizon grid data and transmits it to the control CPU.

Communication CPU: Responsible for receiving control signals and transmitting radio frequency information and robot dog status information to the handle controller.

Integrated control CPU: Based on the real-time data of the other three CPUs, the latest control curve is calculated to control the movement of the robot dog.

Auxiliary CPU: used by third parties for development.

For example, in shooting, the auxiliary CPU controls the work of peripherals based on various data transferred from the comprehensive control CPU. At the same time, control the laser probe to perform auxiliary aiming or ranging.

After listening to Li Yuan's description, the well-informed Mr. Chu knew that that special code was not simple.

I was also shocked again by Li Yuantian’s unconstrained design.

"You kid, you can do it!

However, this is just a toy, how can it be used in actual combat? "

Li Yuan chuckled, walked to a cabinet, opened the door, and took out a metal module with a square tray at the bottom.

Above it is a bracket that looks like it could hold an assault rifle.

Li Yuan walked to the robot dog with the metal module, and the child representative stopped the robot dog wisely.

Li Yuan opened a cover on the back, put the lower tray of the metal module into it, and twisted it hard.

With just a click sound, the module stood firmly on the back of the robot dog.

Then he pulled out a plug and inserted it into the tray with a squeaking sound. There was a burst of motor sound, and then an indicator light on the tray changed from red to green.

"Everyone, if you put an assault rifle here, just hang this hook on the trigger and you can control the fire with your left index finger."

"Then, how to aim?"
