【Chapter 505】Deep into hell (2)
This kind of mechanical dog for detection was developed by Xia State in response to street fighting. It only relies on people's own vision. Windows, corners, and potholes are full of potential risks. Although there are now a series of detection tools such as thermal imaging, The main battle is not some improvised "Army of All Nations", so there must be corresponding countermeasures, not to mention that the enemies that Xia State encounters at this stage are most likely to be the Western camp headed by Country M. It is not a joke. , In terms of war, Xia Guo does have a gap that cannot be ignored due to problems in actual combat experience and weapons research and development concepts.
Drones and mechanical dogs are naturally the most feasible "third eyes". Due to the limitations of drones in terms of noise, load-bearing and technical foundation, the Xia State military has a soft spot for mechanical dogs for ground units. This kind of The driving methods of quadruped robots are mainly divided into three categories: hydraulic actuators, pneumatic actuators and electric actuators. Electric actuators have high control accuracy, but can bear a small load; pneumatic actuators are difficult to control due to their nonlinear characteristics; hydraulic actuators are widely used due to their strong power. Of course, military use naturally uses double insurance. That is, the power system is hybrid to ensure the ability to adapt to the environment and unexpected situations.
As for its principle, it is actually an extension of bionics. It uses curved rods and connecting rods to drive the quadruped robot alternately, simulating the four-legged walking of animals. After the simple gait design is completed, it is combined and connected with an infrared proximity sensor. According to the working principle of the infrared proximity sensor, it becomes a quadruped robot that can track light sources. When the quadruped robot is moving forward and the robot's sensor detects an obstacle 10cm directly in front of it, the quadruped robot will choose to retreat;
For example, when the robot's sensor detects an obstacle 10cm to the left, the quadruped robot chooses the side close to the light source, that is, the robot turns right; when the robot's sensor detects an obstacle 10cm to the right, it chooses to go to the right. Turn left. The sensor is integrated with the gait of the quadruped robot to realize the light source tracking of the quadruped robot.
Of course, there are definitely significant differences between the military version and the civilian version. The detection equipment and attack units they are equipped with are not comparable to those of civilian mechanical dogs, but in terms of their essential mechanisms, the two are indeed like this. The leader of the investigation team waved downwards. After waving his hand, the mechanical dog immediately started moving, turning its head like a camera around, and then began to move quickly. It quickly entered the mall from the cashier counter at an alarming speed. , the cruel and bloody scenes imagined did not appear in the eyes of the operator. On the contrary, the goods on the containers were neatly placed here, and there was no trace of the crowd's fear at all.
"Head, no potential enemies were found at the entrance of the mall. Do you want to enter?"
The team leader thought for a moment, stretched out his arm to his side, flexed his elbow, raised his wrist to the height of his cheek and made a fist, with his palm facing the recipient, indicating that he understood, and asked one of them to stay in place to operate for the technician. The personnel provided protection, and the remaining four people took into account all angles and began to advance cautiously into the shopping mall hall. After all, relying on a mechanical dog is not a reliable thing. The disadvantage of relying too much on this technological investigation method is the loss of fighter jets. After all, the purpose of investigation is to provide sufficient intelligence and information support for one's next actions. It would be troublesome to obtain the risk control situation at the entrance of the mall but dare not enter. It would be troublesome to wait for the enemy to react before advancing.
In this way, the four people cooperated with the information transmitted by the mechanical dog in real time and quickly searched several nearby product areas. However, the results were very similar, and no real traces of resistance were found:
"Are all the people in this underground mall accomplices in the plan? No! Such a problem cannot occur with such a large number of people moving. It seems that they were coerced by some irresistible factor and had to give up all resistance. To obey the other party's instructions, but like this..."
Before the team leader could think clearly, he suddenly heard a low muffled sound, followed by the sound of something heavy falling to the ground, and then an urgent call came from his headset:
"Team leader, the mechanical dog lost control, and Nightingale was also affected and fell into a coma."
This robotic dog, codenamed "True Ting", uses a cutting-edge semi-neural access method. Although it does not reach the level of neural access, it relies on the control of the hands and head to communicate and cooperate, allowing the operator to abandon the previous For complex operations, you can control them with your own movements and eyes, which greatly improves the accuracy and sensitivity of the control. However, there are still problems. After all, there are gains and losses, because the control unit of the mechanical dog interacts with the operator's perception and part of the nerves. With a deeper connection, if the mechanical dog is destroyed or attacked, it will cause the operator to be knocked unconscious by a momentary influx of information and an electric current triggered by an overload of the controller.
At this time, the operators of the reconnaissance group encountered such a problem. Realizing that the front was grounded, the leader of the first group made a prompt decision and informed the second group of the situation here that was preparing to enter the battlefield. Their mission was not to assault, but to conduct reconnaissance. Intelligence supports subsequent armed control through information, so weapons and personal equipment are disguised as cover and defense. If they really encounter a battle, the weapons they carry will definitely be somewhat dwarfed, especially when the enemy they are about to face is likely to be Certain inhuman beings...
"Open the safety, No. 2 and No. 3 use armor-piercing bullets, and No. 4 and I use mixed magazines of copper-core bullets and incendiary bombs to start armed reconnaissance of suspicious areas. If necessary, we can start the attack directly after giving a warning without success. The second group has received the Come in, we need to figure out who our enemy is before they arrive?"
Several crisp mechanical triggering sounds were heard immediately. After the equipment was completed, the four people began to advance to the place where the mechanical dog lost its link according to the planned route. But at the same time, the information received in the temporary command post outside the isolation layer but it is:
"Report has been...attack has begun, area...area control is in progress..."
The information reported by the reconnaissance group was replaced with another paragraph with a completely different meaning starting from the third word, covering up the warning that they were preparing to land with the unknown enemy. Otherwise, the commanding colonel frowned slightly and listened a little. Intermittent communication content, his many years of command experience told him that there seemed to be some hidden danger or uneasiness, but he could not let other combat teams go to support just because of his own feeling, otherwise he would not know the enemy's situation clearly. Under the circumstances, blindly sending people down would be a total loss of life, not to mention that with his authority, he knew with a high probability that his troops were encountering enemies related to alien civilizations.
He personally called back several times, and the communicator still received reports that no enemies were encountered during the reconnaissance operation. Everything seemed to be moving in the best direction, but this strange ease made the colonel even more vigilant. After hesitating for a moment, he still called the head of the combat team and ordered the second group of assault personnel to enter the mall to provide support equipment. As the order was issued, a "shield" with a height of two meters first appeared at the isolation checkpoint in front of the mall. Speaking of shields, it would be better to say that this is a soldier wearing a simple exoskeleton, but he controls two mechanical walls to lift a black shield in front of him.
Although this kind of exoskeleton power device looks a bit simple, in terms of front row cover, as long as the protection can be guaranteed, the simpler the better. Although Xia Guo's research on exoskeletons is not the world's leading, it still has its own Results, so although this mobile "shield" feels a bit useless, when faced with explosive weapons and area-of-effect weapons, the role it can play is the most practical value.
After passing the scan, the big guy and the other eight teammates armed with various heavy weapons entered the mall. Although they did not understand why they were allowed to carry these heavy weapons in a hostage rescue operation, was it that they were allowed to Russia? Anti-terrorism to eliminate all risks? Of course, they also knew that this idea must be a joke. Although they had to admit that counter-terrorism operations that did not take into account the hostages were the most efficient and fastest, but morally, morally or legally, this kind of thing would not happen in Xia Kingdom. The probability is close to nothing.
When the assault force began to prepare to enter, the reconnaissance team also came to a fire door. The door was opened by a small crack. It seemed that this was the trace left by the mechanical dog when it passed through. They took out the endoscopic gun to confirm the fire door. After there was no trap or enemy ambush at the other end, the reconnaissance team leader made a fist with his hand and stretched out his arm horizontally to indicate the formation of a horizontal column. Then he gently pushed open one side of the fire door and followed the gradually expanding field of view with his gun. Mouth alert, the team leader soon discovered a bunch of dark red things appearing behind a towering shelf about ten meters away from him. He could vaguely make out people's faces from the gaps in the shelves and the exposed parts above. contour.
He immediately thought that this was a hostage being controlled, so he asked the remaining three people to follow him and open the fire door to check. The constantly rising music in the mall seemed to cover some sounds, making the team leader aware that A little strange, but in order to prevent those survivors from being further persecuted, they did not stop because of the uneasiness in their hearts, but moved little by little along the angle of the edge of the container, hoping to see what was behind the shelves from a longer distance. .....
