Chapter 76 The amazement and excitement of military personnel (please order for the first time!)
In the indoor shooting range of the base, human-shaped targets are neatly arranged to simulate target objects.
These targets can perform various complex movement trajectories and avoidance actions to test the tracking and hitting capabilities of weapons.
At this moment, in the human-machine collaboration mode, only armed robots were seen holding heavy rifles.
The rifle is connected to the computer and fire control system built into the armed robot. The connection method is still mainly wired, because the signal transmission is more stable and reliable. Stability and reliability are essential indicators for military equipment.
Rich real-time data information is displayed on the operator's first-person UI interface, and real-time information is displayed on the edge of the angle of view to ensure that it does not affect the main angle of view,
In addition, the transparency of the displayed information in the viewing angle can be flexibly adjusted.
In the lower left of the viewing angle is the information of the weapon system. At this moment, the information data of the rifle and the remaining amount of bullets in the magazine are displayed [200/200]
The lower right viewing angle displays the operator’s vital sign data, such as body temperature, respiration, blood pressure, heart rate, etc.
A small model of an armed robot is displayed in the center of the lower part of the viewing angle. This is the real-time status information panel of the armed robot, such as power supply, power status, etc.
When the armed robot is attacked, the body structure is damaged.
For example, if the shoulder armor is damaged, the small model on the panel will light up a warning color on the shoulder armor. Different colors represent the degree of damage.
When the armed robot is intact as a whole, the overall color of the small model is light blue, and the degree of damage from light to heavy gradually changes from light blue, light yellow, dark yellow, light red, and dark red.
The entire perspective UI interface allows the operator to clearly grasp the real-time information status of himself and the armed robot at a glance.
It is worth mentioning that when the Luan team first designed the heavy rifle used by the armed robot, they put a small LED panel on the side of the gun body to display the number of bullets remaining in the magazine.
However, this component was later removed.
Because the enemy may also see it on the battlefield. If the magazine is seen empty, the power against the enemy will be reduced.
So the display component has been removed. Even if the magazine is empty, only you know it, and the enemy cannot tell whether there are bullets in the gun. Unless you meet Yan Shuangying who can bet that there are no bullets in your gun, this is a concept god with no solution.
At this time, the operator on the omnidirectional motion platform has received the notification sent to him by Fu Chen.
He took a deep breath and turned on the rifle's intelligent auxiliary aiming system.
In an instant, an indicator light on the side of the armed robot's head suddenly flashed, indicating that the intelligent auxiliary aiming system had been activated and was rapidly scanning the surrounding environment.
However, the light emitted by the flashing light is not in the visible light band and is invisible to the naked eye. Special equipment is required to detect it.
A number of static targets were raised at the other end of the shooting range. The first one started was the static target shooting at a close range of 100 meters.
The operator's first-person perspective screen, the target in the field of view is scanned, and a red beacon appears on the target to be marked.
Two real-time movable beacons will appear in the perspective, one is a circular beacon and the other is a cross star beacon.
The circular beacon is a real-time tracking of the human eye's dynamic vision. The cross star beacon is the center of the weapon, but it is not fixed at the center of the visual angle like in FPS games. It also moves in real time because it is synchronized in real time according to the ballistic path of the muzzle of the rifle. The cross star beacon will move synchronously with the muzzle of the rifle.
If the muzzle of the gun is pointed outside the viewing angle, the cross star beacon will disappear from the viewing angle. This is to tell the operator that when the gun is fired at this time, the ballistic path of the bullet will not appear within the viewing angle.
When locking on an attack target, the circular beacon moves to the target. When it is determined to hit the target, a red beacon will appear on the target to mark it. This red beacon will always be anchored to the target and will disappear unless the operator actively removes it.
Then the operator controls the weapon to move the cross star beacon to the red beacon. When the two beacons intersect, the red beacon will immediately turn into a green beacon.
The operator controlled the armed robot to point the rifle at the target in the field of view. The cross-star beacon intersected with the red beacon on the target, and the red beacon immediately turned into a green beacon.
In this process, the operator only controls the armed robot to hold the rifle to roughly aim at the target, and let the cross star beacon in the visual field move toward the red beacon. The intelligent auxiliary aiming system will further intelligently fine-tune it to achieve precise aiming.
When a red beacon appears on the target, the target confirmation is completed; when the red beacon turns into a green beacon, the target is locked.
After the red shape turns green, the operator decisively pulls the trigger for burst shooting.
Bang! !
With the sound of a gunshot, the target was successfully hit and fell down.
Immediately afterwards, the operator pointed to another target, and the red beacon turned to green.
shoot again and hit the target accurately.
The shooting range began to ring with gunshots continuously, and the static targets fell down one by one, and soon 100 targets were hit.
Then there is a 200-meter mid-range shooting test, which is also 100 targets; and then there is a 300-meter long-range shooting test, which is also 100 targets.
The operator proceeds one by one, and other members of the technical team are also collecting data.
ifies in static target shooting at 100 meters, with a 100% hit rate at close range and 10 rings; at 200 meters at mid-range, a 100% hit rate at 10 rings;
"Good guy, it's 100% accurate, the bullet is perfect!"
The most important thing is that Li Fengting and others present know that the operator is a technical engineer of Yuanjie Intelligent Control.
He is not an active combatant, nor has he undergone long-term and professional military training, but he can achieve a 10-point hit rate by controlling an armed robot, making him a sharper than the sharpshooters in the army.
This is simply a dimensionality reduction strike. People in the army such as Li Fengting were shocked and excited. Next, the shooting range began to conduct a moving target shooting test.
As the order was given, the targets began to move irregularly. They were very fast, some moved left and right laterally, some showed an S-shaped route, and some suddenly accelerated and decelerated, simulating the flexible and unpredictable movements of the enemy in actual combat.
The operator only needs to control the armed robot to aim the rifle roughly in the direction of the target, without deliberately aiming.
In a short period of time, advanced sensors capture the target's movement information, and optical sensors quickly identify the target's appearance features. This information will be transmitted to the built-in computer of the armed robot, which processes the data at an astonishing speed.
Quickly calculate the distance, speed, movement trajectory and other parameters of each target, and predict the target's position in the next second or even the next two seconds based on this information.
At the same time, combined with the data parameters of the firearm, such as the initial velocity of the bullet, flight time, gravity effect, etc., the best aiming point and shooting timing can be quickly obtained.
From the operator's perspective, it's not that complicated. Just aim roughly at the target, pay attention to the change in color of the beacon, and pull the trigger immediately when it turns green.
The sound of gunfire continued in the shooting range, and the moving targets fell down one after another.
The shooting test of the moving target was also tested at 100 meters close range, 200 meters mid-range and 300 meters long range.
As the last moving target of the 300-meter long-distance test was knocked down, the test ended.
"Dynamic target shooting has a 100-meter short-range hit rate of 98% and a 10-ring hit rate; a 200-meter mid-range hit rate of 96% and a 9.5-ring hit rate; a 300-meter long-range hit rate of 92% and a 9-ring hit rate."
Military technical experts who were watching the test couldn't help but admire: "With such a high shooting frequency, it can also have such a high accuracy, with more than 90% hits in the 9th ring. This auxiliary aiming system is simply amazing."
Li Fengting and others were all very satisfied and extremely excited when they saw the results of the first test.
Because they all know that this means that with the support of the intelligent auxiliary aiming system, every warrior who controls an armed robot can become a super soldier king, a sharpshooter with terrifying accuracy.
There are a few sharpshooters in a combat company, and all the commanders and fighters are sharpshooters, which are two different things.
The improvement of the overall combat effectiveness of the combat troops will definitely be doubled.
Finally, Lu An introduced the intelligent auxiliary aiming system of the armed robot to the people present.
Compare and determine the location and characteristics of the target. The thermal imager can detect target units hidden in dark places or complex environments based on the target's thermal radiation." Li Fengting and the military technical experts who were watching couldn't help but nodded. No wonder it was positioned as a rifle, and the empty gun weighed 11 kilograms.
Lu An continued: "We have developed a complete set of data processing and calculation systems specifically for it. By connecting the built-in computer and fire control system of the armed robot, the rifle will quickly process and analyze the data obtained by the target recognition system in real time." Measuring the future position of the target. At the same time, the shooting parameters of the firearm, such as the initial velocity of the bullet, the impact of gravity, etc., will be used to determine the best aiming point and shooting timing. "
"Based on the calculation results of the fire control system, the steering mechanism on the gun body will automatically adjust the direction of the barrel to align it with the target."
"In short, the warrior operating the armed robot roughly aims at the target position, confirms the attack target, the fire control system will be further fine-tuned, and then the warrior only needs to press the attack command according to the beacon prompts."
One of the military technical experts asked: "With so many high-tech components and precision structures integrated, how adaptable and stable is it to the environment?"
Hearing this, Lu An replied with a smile: "Of course, as a military product, the most important thing is reliability and stability. This rifle is mainly made of leather and has the characteristics of high stability and reliability. I am very confident in it. I just need the actual measured data to prove it."
In most cases, the more high-tech and high-precision things are often not so durable, and will stop working if they bump into it.
But for military products, they are most afraid of losing their chain at critical moments, so military products pursue stability and reliability more.
Lu An certainly knows this. The armed humanoid robot is a big man of 2.3 meters in body and weighs more than 300 kilograms. The design of such a huge body is to create powerful force and psychological pressure on the enemy. Secondly, a larger body means more space, so there is no need for too precise parts.
For example, for built-in computer chips, 28nm or even 32nm chip technology is completely sufficient.
From a manufacturing process perspective, the commercial chips used in many smartphones are more technologically advanced than the chips used by armed robots. The computing power requirements of armed robots are actually not low, but they do not require such high-end chips to meet the standards. The reason is that there is more space.
Smartphones are about the size of a palm, and space resources are at a premium. Chips need to be miniaturized and have higher performance, and the process is naturally demanding.
It is also harsh on the operating environment.
However, with a body as big as an armed robot, there are enough space resources to use a desktop-level chip processor. Its absolute performance is still faster than that of higher-end smartphones. The space brought by the huge body can be used to stuff several computer hosts without any problem.
If you need more computing power, just integrate a few more chips.
Moreover, there is no need to worry about old magnesium getting stuck at the wafer level.
In fact, many high-tech weapons and even the chips in missiles can be used by removing the chips from the motherboard of a household washing machine.
Military equipment and civilian products are two different ideas. The most important thing for military products is that they are durable, stable and reliable, and do not lose their chain at critical moments.
Otherwise, no matter how advanced the equipment is, it will be in vain if it becomes unusable at a critical moment.
It is worth mentioning that if the auxiliary aiming system is destroyed, the gun can still be used normally. At this time, the accuracy depends on the operator's personal ability, so the marksmanship that should be trained still needs to be trained.
In the following days, Lu An led the technical team to continue testing, collect data, and adjust and optimize the technology based on massive real-time data feedback.
Ten days later, the technical team began testing the remote control of the armed humanoid robot.
Lu An asked the technical team to be divided into three teams, and each team member took an omnidirectional motion platform to stand-by at straight-line distances of 500 kilometers, 1,000 kilometers, and 1,500 kilometers from the military base.
"Group A is ready."
"Group C is ready."
"Group B is ready."
Lu An at the base heard the reports from the three groups and immediately said to Fu Chen next to him: "Let's get started."
Fu Chen nodded and immediately sent a message to each group.
After a while, three armed robots in the indoor shooting range of the base were awakened. They all held a heavy rifle in their hands.
A large number of moving targets were activated in the shooting range, and the operators controlling three armed robots were located at places 500 kilometers, 1000 kilometers and 1500 kilometers away from the base.
The picture of the indoor shooting range is also presented in the operator's first perspective.
The problem of network signal delay is a very important factor in controlling armed robots.
If the delay is too high, the picture the operator sees is out of sync with the frontline battlefield, which will greatly weaken the battlefield situational awareness, and the bullet will not hit the target when launching an attack. At this time, the auxiliary aiming system can shine, and it can still achieve high accuracy under high delay conditions.
Because the auxiliary aiming system itself has no delay, what is delayed is the feedback from the frontline signal to the operator's UI interface.
With the continuous sound of gunfire, the three armed robots hit the moving targets one after another.
On the other side, Lu An asked on the communication channel: "Each group reported, what is the ping value of your current real-time delay."
Li Fengting was also observing in the hall. The test being conducted today is to measure the signal delay of the remote wireless control armed robot.
"The signal of Group A is stable at 95ping."
"The signal of Group B is 190ping."
Lu An immediately said after hearing this: "Where is Group C? Group C reports."
"Group C has a delay of about 350 ping."
Li Fengting, who was watching next to him, couldn't help but cheered and said: "Not bad, really good. Group B is at such a distance of 1,000 kilometers, and the signal delay is unexpected. The ping value is not more than 200, which is much lower than the delay of the drone model." Hearing this, Lu An turned to look at Li Fengting and said with a smile: "The two are not very comparable. The speed of the aerial vehicle is hundreds of kilometers per hour or even subsonic speed. The faster the target moves, the greater the signal interference caused by the Doppler frequency shift effect."
"As a ground combat unit, armed robots are basically not affected by the Doppler frequency shift effect."
Li Fengting couldn't help but nodded.
In addition to the operators in Group A who felt that the delay had almost no impact, the operators in the other two groups obviously felt that the delay was relatively large. In particular, the ping values of Group C exceeded 300, and the real-time picture had obvious frame drops.
If you are playing games, a delay of more than 200ping is definitely extremely uncomfortable.
But in Li Fengting's eyes, this data is definitely far beyond his expectations. You must know that some current consumer drones usually have a ping value between 50 and 100 ping within a short range of tens of meters.
But if the distance increases to a few hundred meters, the ping value may reach between 100 and 200ping.
In military applications, if remote control is carried out through satellites or complex network links, the ping value of the drone will be higher, and it is common for the ping value to exceed 300.
There are many factors that affect the ping value.
There is a factor of communication distance. The farther the distance, the longer the signal transmission time and the higher the ping value.
There are factors such as communication frequency band and protocol. High frequency bands such as 5.8GHz usually have lower latency than low frequency bands such as 2.4GHz.
There are factors such as environmental interference, building blockage, electromagnetic interference, etc. that will increase delays.
There are also factors related to device performance. Hardware performance, software algorithms, etc. will also affect the fluctuation of ping value.
