A senior officer dressed in major general's costume walked towards Duke in the strong wind blowing from the helicopter, "Director Du, thank you all the hard work! I am Chen Weihong, deputy commander of the South China Sea Fleet. On behalf of all the officers and soldiers of the South China Sea Fleet, I am very grateful to President Du for taking time out of his busy schedule to participate in this rescue activity." The visitor saw Duke coming down and saluted solemnly.

Facing Duke, a national treasure figure, even as a senior general in the army, Major General Chen Weihong knew that it was not the same order of magnitude in front of Duke, and with his status, it was impossible to invite Duke, the great god. Duke was willing to risk his own risk to participate in this deep-sea rescue, which was a huge support for his work.

Especially when he saw behind Duke, a tall robot was being lifted out by two Marines with difficulty. This great god was the greatest hope in front of him. If this robot could not solve the problem, Major General Chen Weihong didn't know what he should do.

If such a huge accident occurred in his own jurisdiction, the officers and soldiers of the entire submarine were killed or killed, not to mention that the position of deputy commander who had just taken office could not be saved, as the former captain of the submarine detachment, Chen Weihong would not be able to get through conscience all his life. You should know that many of the officers and soldiers on this submarine were old subordinates he had taken before. Therefore, Chen Weihong's salute was not only a sincere thank you to Duke, but also an endless hope for the robot behind Duke.

"It's not hard work, Commander Chen, are you ready for the preparation?" Facing the newly appointed deputy commander of the South China Sea Fleet, Duke had no time to be polite. He stepped forward and shook hands with Major General Chen Weihong, and went straight to the point. On the way here, Duke had already told the front line about his request, asking them to prepare in advance so that they would not waste time when they went to the front line.

There are more than a hundred lives in the submarines waiting to be saved, and Duke can't delay even a minute or a second of time.

"We have completed all the preparations in accordance with the instructions of Dean Du," Major General Chen Weihong was even more grateful when he saw Duke's decisive style. This is what he came to do, not show off.

He is a typical soldier, and Duke is in his appetite. "Now we have mobilized four Jiaolong-class deep-sea submersibles to assist in the completion of this work, two of which are on the seabed of the submarine. Two are leaning next to the search and rescue ships and can dive with supplies at any time to assist in the rescue work."

"The relevant items needed to rescue submarines, such as ultra-high-strength titanium alloy air transport pipelines and other materials, have been transported to the near the crashed submarine. Just wait until the submarine emergency rescue interface is opened. Now all the personnel on the scene, including me, will unconditionally obey Dean Du's command and dispatch." Major General Chen Weihong quickly and concisely introduced the current situation in a few words.

"Okay, let's start." Dukehun didn't think there was anything wrong with this and started commanding without hesitation. "Now, since the robot has not conducted underwater operation tests, I need to make it do some testing work for the depth of the underwater work. Now let the Jiaolong submersible bring it up and dive into the sea..."

Duke said this and paused for a moment. He had to consider how deep it was to get into the water for the first time. After a few twists in his mind, Duke decided to put it to the depth of 500 meters for the first time. Anyway, if this depth is not enough, don't waste the Navy's precious time.

"Do a 500-meter depth test first." Duke said decisively.

Two Marines carried this big guy of more than 100 kilograms. They needed to tie the robot to the Jiaolong submersible and let the Jiaolong submersible be carried out to the bottom of the sea before they were released, and then command it to carry out the rescue mission through remote control.

Soon, the navy personnel made preparations and then brought the remote control device brought by Duke with the Jiaolong submersible. Before going into the water, Duke turned on the remote control and briefly taught the operator of the Jiaolong submersible who was preparing to go into the water to command the basic operation of the robot. The operating interface of this robot is quite humane and the basic operation is simple to master. It took more than ten minutes Duke taught the operator who was preparing to go down.

"Okay, if there is any situation, we can communicate through the sound of water. The most important thing is to pay attention to the various data indicators of the robot in the operating system at any time. If there are yellowing indicators, we need to report to me in time. At this time, do not do big moves. Try to maintain the current status of the robot and report all indicator data to me before doing new operations." Duke finally emphasized that there is no way. Now this robot has not undergone rigorous testing. Duke is not very clear about what the limit situation is. In order to ensure that the robot does not be scrapped in advance, Duke had to open and display the monitoring data on the robot on the operating platform, so that underwater operators can monitor the operation status of the robot at any time.

"Yes! Chief, don't worry, we guarantee that we will complete the task in accordance with the operating specifications!" The three naval personnel operating the Dragon Submersible replied nervously. This thing is a treasure that concerns the lives of more than 100 brothers below. They were afraid that they would fail the rescue work, so the three of them carefully studied and recorded what Duke taught at the same time. Someone next to them took this into a live video and asked them to take it. When they encountered problems, they could take a look at it while asking Duke for instructions.

"Okay, good luck to you!" Duke patted their shoulders, indicating that he should not be so nervous.

300 meters, the robot's index of diving with the Jiaolong submersible is normal, 400 meters, normal! When the Jiaolong submersible stays at 500 meters, it is still normal!

"Reporting to the head, we have dived into a depth of 500 meters, and the robot's indicators are displayed normally." When the images and sounds of the underwater operator came, Major General Chen Weihong and Duke who were staring at the screen on the rescue ship were finally relieved, "We are ready to start the robot power supply and conduct a robotic hand movement test. The power supply is turned on normally, and the remaining power is 100%!"

"The robotic arm moves normally, and the robotic arm bends at 180 degrees normally!..." After a series of tests were normal, Duke's originally hanging heart suddenly felt relieved. It seemed that most of the robots were made of abnormal and expensive materials, which did exceed the design specifications.

"Okay, turn off the power, now we can directly reach the destination to perform tasks." Duke knew that the robot's indicators were very healthy, so he directly ordered. "Pay attention to the changes in various indicators during the dive."

"Yes, leader! Jiaolong One understands!" The operator of the Jiaolong submersible replied loudly. Seeing the robot moving freely at 500 meters, they now have stronger confidence in the robot, and drove Jiaolong One to continue diving. They all reached the point where the submarine was stranded, and the various indicators of the monitoring robot were still in green.

"Chief, Jiaolong 1 is in place! All indicators are normal, please instruct!" The request from the operator Jiaolong 1 came from the water voice.

"Very good, follow the scheduled plan." At this point, Duke finally felt relieved about the robot. It can be seen that those special alloys that are more expensive than gold have not been spent. The redundancy of the robot design seems to be able to adapt to the needs of various seabed situations. In the future, it looks very promising to turn it into a multifunctional robot.

"Director Du, it seems that this robot is very suitable for undersea work. I don't know how long it can work on the undersea, how far it can go, and how much carrying it can be?" Major General Chen Weihong, who was on the side, watched the robot enter the sea, couldn't help but feel moved and asked a question.

"The battery it carries now at 12KWh, and it is not a big problem to carry items less than 50 kilograms. If it is not the maximum speed of walking under the sea, it is estimated that it would be less problematic to move under the sea for 3 hours, so that it can walk more than 15 kilometers." Duke replied. He knew that the senior general around him would pay attention to military purposes again, but the underwater environment is not as good as land. First of all, there are problems with communication and path recognition, and it is difficult to transform this robot into a frogman to launch an underwater attack on the enemy.

"What? The battery it carries is 12KWh?" Major General Chen Weihong didn't expect that this robot had such powerful energy. "How much does the battery weight account for the total weight of the robot?"

This is really amazing. The whole robot is just like an ordinary human. This battery is so awesome that it has such a high power storage capacity. "The battery module is about 10 kilograms, which is our latest lithium-sulfur battery. The production process is still relatively immature and the cost is very high."

Major General Chen Weihong did not notice the cost issue mentioned by Duke. When he heard that this thing was only ten kilograms, it could actually achieve 12KWh. From the mass ratio of energy, it is more than 20 times that of a submarine today. If this new battery is used on a submarine, it will save much precious space. You must know that a general submarine backup battery pack can be calculated by hundreds of tons. If this battery is used, about ten tons will be enough.

The space and weight saved can carry dozens of large torpedoes or submarine-launched missiles. This is definitely a super good thing. Chen Weihong secretly decided in his heart that after the rescue is successful, he must find time to talk to Dr. Duke and see how it is used on our submarines.

After the two of them interrupted, the operators in the Jiaolong-1 submersible had already started the rescue work. After they took the robot to the submarine, they found a foreign compressed air input port that connected to the life-saving emergency port, and asked the robot's robot's robot to hold the lid and prepare to rotate and open it.

In the previous rescue, the wrench-shaped robot equipped with the Jiaolong submersible did not have enough rotational power, and the cover with great power under high water pressure could not be opened.

"Chief, we have found the emergency input port and completed the preparation work. Now we start rotating. The initial output force is set to 100 kilograms!" Jiaolong 1 submersible reported the latest situation and asked for instructions.

"Can be executed!" Duke replied that the maximum output of the robotic arm of this robot design exceeds 200 kilograms, so there should be no problem with this power setting.

"Report, under the 100 kg force setting, the emergency port cover cannot be opened." Soon, the operator of Jiaolong One feedback returned the latest information, "The battery power consumption is very fast, and the remaining battery capacity is now 70%!"

When Duke heard this news, he frowned. This was bad news. Judging from the total reserve energy of the battery, it should not be consumed so quickly. However, a cover that a normal diver could easily open at a depth of one or two hundred meters could not be opened, and the water pressure at the bottom of the sea was beyond Duke's expectations.

"Try increasing the output power to 150 kilograms!" Duke ordered.

"Chief, the lid still remains unmoved!" Soon, the underwater feedback still failed.

"Continue to increase the strength to 200 kilograms!" Duke once again raised the output power to near the upper limit of the design specifications.

"Okay, now the lid is loose." The operator's happy voice had not disappeared from Duke's ears, and soon a new exclaim came from the bottom of the water. "Chief, the battery capacity is declining sharply, and the remaining power is now fifty percent!"

Oops! Duke finally realized that at the deep sea bottom, the temperature was very low, and the operating temperature of the battery was reduced too much, which greatly affected the performance of the battery. He did not pay much attention to this issue when designing the battery, and now he can only grab the time.

"Continue to increase the output force to 210 kilograms and speed up the process!" Duke had to fight to this point. Fortunately, when he came this time, he specially brought an additional backup battery, hoping that the first battery could open the lid smoothly.

"Yes!" The operator of Jiaolong No. 1 gritted his teeth and continued to increase the output power of the robot. The loose cover began to rotate faster, but as the output power increased, the battery consumed faster. Later, the battery capacity dropped by one grid almost every few seconds. When the cover was turned 70%, the red light on the operating table flashed, and a sharp alarm was issued, and the power was finally insufficient!

"Switch off the power and float up and replace the battery!" Duke heard the sound of water and ordered without waiting for the operator of Jiaolong 1 to report.

With the experience last time, Duke has understood the fatal disadvantage of his robot battery, that is, the performance declines quickly at low temperatures. Therefore, when the new battery was replaced for the second time, Duke asked someone to perform some primary cold-proof treatment near the robot battery to alleviate the speed of the internal temperature drop. Then he ordered the operator of Jiaolong 1 to speed up the diving action, and after arriving at the destination, he directly increased the output force to 210 kilograms to quickly lift the cover of the lifeguard, and then installed the emergency titanium alloy air input pipeline.

Finally, before the robot's power was exhausted, the life-saving air input pipeline was successfully installed for the submarine!

Duke secretly let out a sweat amid the cheers of naval officers and soldiers on the sea. Fortunately, he brought a backup battery this time, otherwise he would not know how to end it. Personal shame is a small matter. The lives of hundreds of officers and soldiers were in his mind. Although the robot's use environment completely exceeded the design specifications, this incident still gave Duke a deep lesson, that is, the quality control and testing of product performance is worth it, especially the research on weapons. The environment used is not as ideal as expected. He has to consider his performance under various extreme conditions in the future.

Otherwise, once you face today's special environment, if you didn't think about the difficulties when you set out, it would have become a bloody lesson!

Amid the cheers of the officers and soldiers at the scene, no one expected that this extremely successful deep-sea rescue in the eyes of the officers and soldiers gave Duke a great touch, making the quality of military products in the future of DSM the top level of the global weapons and the most reliable dependence of the People's Liberation Army for the four parties to fight.
