A senior officer dressed in the uniform of a major general walked towards Duke in the strong wind blowing from the helicopter, "Dean Du, I have worked hard all the way I am Chen Weihong, deputy commander of the South China Sea Fleet, and on behalf of all the officers and men of the South China Sea Fleet, I am very grateful to Dean Du for taking time out of his busy schedule to participate in this rescue activity. When the visitor saw Duke come down, he saluted solemnly.

In the face of Duke, a national treasure, even as a senior general in the army, Major General Chen Weihong knew that he was not of the same order of magnitude in front of Duke, and it was impossible to invite Duke, a great god, to come with his status. Duke Ken risked his life to participate in this deep-sea rescue as a huge support for his work.

Especially seeing that behind Duke, a tall robot was being carried out by two marines with great difficulty, this great god was his greatest hope in front of him, if this robot could not solve the problem, Major General Chen Weihong did not know what to do.

If there is such a big accident that causes casualties among the officers and men of the entire submarine in his own jurisdiction, not to mention that the post of deputy commander who has just taken office cannot be kept, as the former head of the submarine detachment, Chen Weihong will not be able to get by in his conscience for the rest of his life, and you must know that many of the officers and men on this submarine are old subordinates he once led. Therefore, Chen Weihong's salute is not only a sincere thank you to Duke, but also an infinite hope for the robot behind Duke.

"It's not hard, Commander Chen, have you done all the preparations?" In the face of the newly appointed deputy commander of the South China Sea Fleet, Duke did not have time to be polite, and after shaking hands with Rear Admiral Chen Weihong, he went straight to the point. On the way in, Duke had already told the front line of his request, asking them to prepare in advance, so as not to waste time when they arrived at the front line.

Now there are more than 100 lives in the submarine waiting to be saved, and Duke can't afford to waste even a minute or a second.

"We have completed all the preparations in accordance with Dean Du's instructions," Major General Chen Weihong was even more grateful when he saw Duke's vigorous and resolute style, this is what we are here to do, not to put on a show.

He's the quintessential military man, and Duke is exactly what he likes. "Now we have mobilized four Jiaolong-class deep-sea submersibles to assist in this work, two of which are on the bottom of the submarine where the submarine is stranded, and two are leaning next to the search and rescue ship to dive with supplies at any time to assist in the rescue work."

"The relevant items needed to rescue the submarine, such as ultra-high-strength titanium alloy air transmission pipelines and other materials, have now been transported to the vicinity of the wrecked submarine, just wait for the submarine emergency rescue interface to be connected. Now there are personnel, including me, who will unconditionally obey the command and dispatch of Dean Du. Major General Chen Weihong gave a quick and concise introduction to the current situation in a few words.

"Okay, let's get started." Du Kehun didn't think there was anything wrong with this, and unceremoniously began to command, "Now that the robot has not been tested underwater, I need to make it do some testing work on the underwater working depth." Now let the Jiaolong submersible take it and dive to the bottom of the sea......"

Duke said this, paused, he wanted to think about how deep the first time to enter the water is appropriate, after a few turns in his mind, Duke decisively decided to put it to a depth of 500 meters for the first time, anyway, if this depth is not good, don't waste the precious time of the navy.

"Let's do a 500-meter depth test first." Duke said decisively.

Two marines carried the big guy with more than 100 kilograms, and they needed to tie the robot to the Jiaolong submersible, let the Jiaolong submersible be brought to the bottom of the sea before releasing it, and then command it to carry out rescue missions through remote control.

Soon, the Navy personnel made preparations, and then brought the remote control device brought by Duke to the Jiaolong submersible, and before going into the water, Duke turned on the remote control and briefly taught the basic cāo work of the robot to the Jiaolong submersible who was about to be launched. The interface of this robot is quite human, and the basic cāo is simple to master, and it took more than ten minutes for Duke to teach the cāo who is ready to dive.

"Okay, what is the situation we can communicate through the underwater acoustic phone, the most important thing is to pay attention to the data indicators of the robot in the cāo control system at any time, if there are yellowing indicators, you need to report to me in time, do not make big moves at this time, try to maintain the status quo of the robot and report all the indicator data to me before I can do a new cāo." In order to ensure that the robot will not be scrapped in advance, Duke has to open the monitoring data on the robot and display it on the cāo platform, so that the underwater cāo personnel can monitor the operation of the robot at any time.

"It's the chief, rest assured, we promise to complete the task in accordance with the cāo specifications" The three navy personnel of the Jiaolong submersible replied nervously together, this thing is related to the lives of more than a hundred brothers below, they are afraid that they will do something wrong and make this rescue work fail, so the three of them carefully studied and recorded what Duke taught at the same time, and there were people next to them who made a live video of this and asked them to take it down, and if they encountered problems, they could ask Duke to take a look at it at the same time.

"Alright, good luck guys" Duke patted them on the shoulder, signaling not to be so nervous.

At 300 meters, the indicators of the robot diving with the Jiaolong submersible are normal, and 400 meters is normal when the Jiaolong submersible stays at 500 meters

"Report chief, we have dived to a depth of 500 meters, and the indicators of the robot are normal," When the images and voices of the underwater crew came up, Major General Chen Weihong and Duke and others who were nervously staring at the screen on the rescue ship finally breathed a sigh of relief, "We are ready to start the power supply of the robot and test the manipulator action, the power supply is turned on normally, and the remaining power is 100%"

After ......a series of tests normal, Duke's original hanging heart suddenly became steady, and it seems that most of this robotic robot is made of perverted expensive materials, and it does have a performance beyond the design specifications.

"Okay, turn off the power, now we can go directly to the destination to carry out the mission" Duke ordered directly after knowing that all the indicators of the robot were very healthy. "Pay attention to the changes in various indicators during the dive."

"Yes, the chief Jiaolong No. 1 understands," the Jiaolong submersible Cāo replied loudly, seeing that the robot moved freely at a depth of 500 meters, they now have stronger confidence in the robot, and began to continue diving in Jiaolong No. 1. All the way to the place where the submarine ran aground, the various indicators of the monitoring robot were still in a green state.

"Chief, Jiaolong No. 1 is in place, all indicators are normal, please instruct" The voice of Jiaolong No. 1 Cāo came from the water acoustic phone.

"Very good, according to the predetermined plan." At this point, Duke is finally relieved about this robot, and it can be seen that those special alloys that are more expensive than gold are not in vain, and the redundancy of the robot design seems to be able to adapt to the needs of a variety of undersea situations, and it looks very promising to build it into a multi-functional robot in the future.

"Dean Du, it seems that this robot is very suitable for working on the bottom of the sea, I don't know how long it can work on the bottom of the sea, how far it can go, and how much carrying capacity it can have?" Major General Chen Weihong, who was on the side, watched that everything was normal when the robot entered the sea, and couldn't help but move in his heart, and asked a digression.

"Now it carries a reserve battery of 12kh, and it is not a big problem to carry items within 50 kilograms, if it is not for the maximum speed of walking on the seabed, it is estimated that it should not be a big problem to be active on the seabed for 3 hours, so that it can go out of more than 15 kilometers." Duke replied. He knew that the senior general around him had focused on military use again, but the underwater environment was not as good as that on land, first of all, there were problems with communication and path recognition, and it was difficult to transform this robot into a frogman to launch an underwater attack on the enemy.

"What, it carries a battery with 12kh?" Major General Chen Weihong didn't expect this robot to have such powerful energy, "How much does the weight of the battery account for the total weight of the robot?"

This is really a bit surprising, the whole robot is like the size of an ordinary person, how much does this battery have to have such a high power storage capacity. "The battery module is about 10 kilograms, which is our latest lithium-sulfur battery, and the production process is still relatively immature and the cost is very high."

Rear Admiral Chen Weihong did not notice the cost problem mentioned by Duke at all, he heard that this thing is only ten kilograms, and it can do 12kh, from the mass specific energy calculation, this is more than 20 times the current submarine use battery, if this new type of battery is used in the submarine, how much valuable space will have to be saved, you must know that an ordinary conventional submarine spare battery pack is hundreds of tons of calculation, if you use this kind of battery, ten tons is enough.

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

The two of them broke down, and the cāo crew in the Jiaolong No. 1 submersible had already begun rescue work. After they brought the robot to the submarine, they easily found a connection to the external compressed air input port of the life-saving emergency port, and let the robot's manipulator hold the lid and prepare to rotate it open.

In the previous rescue, due to the insufficient rotation force of the wrench-like manipulator equipped with the Jiaolong submersible, it was impossible to open the cover, which has a lot of power under high water pressure.

"Chief, we have found the emergency input port and completed the preparations, and now we are starting to rotate, and the initial output force is set at 100 kilograms," the Jiaolong-1 submersible asked after reporting the latest situation.

"Yes," Duke replied, adding that the robot designed the robotic arm to output a maximum force of more than 200 kilograms, so this power setting should be no problem.

"Report, under the force setting of 100 kg, the emergency port cover cannot be opened." Soon, the Jiaolong No. 1 Cāo staff returned the latest information, "The battery drains quickly, and now the remaining battery capacity is 70 percent."

Hearing this, Duke frowned, this is not good news, according to the total reserve energy of the battery, it should not be consumed so quickly. The lid, which can be easily opened by a normal diver at a depth of one or two hundred meters, cannot be opened with a force of 100 kilograms, and the water pressure on the seabed is beyond Duke's expectations.

"Increase the output to 150 kilograms," Duke ordered.

"Chief, the lid still doesn't move" quickly, the underwater feedback still does not work.

"Continue to increase the power to 200 kilograms," said Duke, who once again raised the output to around the upper limit of the design specification.

"Okay, now the lid is loose." The cāo crew's voice of delight had not yet disappeared from Duke's ears, and soon a new exclamation was heard from underwater. "Chief, the battery capacity is declining sharply, and now the remaining power is 50 percent"

Oops Duke finally reacted, in the deep seabed, due to the very low temperature, the operating temperature of the battery has been reduced too much, which greatly affects the energy of the battery.

"Continue to increase the output to 210 kilograms and speed up the process" Duke had to fight for this job, but fortunately, when he came this time, he deliberately brought an extra spare battery, hoping that this first battery could open the lid smoothly.

"Yes" Jiaolong No. 1 cāo staff gritted their teeth and continued to increase the output power of the manipulator, and the loose lid began to rotate faster, but with the increase in output power, the battery consumption was faster, and later, almost every few seconds, the battery capacity dropped by one bar, and when the lid was unscrewed seventy percent, the red light on the cāo platform flashed, and at the same time sent out a sharp report jǐng, and the power was finally insufficient

"Turn off the power and float to replace the battery," Duke could hear the voice from the underwater phone, and ordered without waiting for Jiaolong No. 1 to report to the personnel.

With the last experience, Duke has understood the fatal flaw of his robot battery, that is, the xìng can drop quickly at low temperatures, so when the new battery is replaced and set off for the second time, Duke asked people to carry out a flocculent cold-proof treatment near the robot battery to alleviate the speed of the temperature reduction inside the battery, and then ordered the Jiaolong No. 1 cāo crew to speed up the diving action, and after arriving at the destination, directly increase the output force to 210 kg to quickly lift the lid of the life-saving port. Then install the emergency titanium alloy air input pipeline.

Finally, before the robot ran out of power, the submarine was successfully installed with a life-saving air input pipe

In the cheers of the naval officers and sailors on the sea, Duke secretly wiped a handful of sweat, fortunately he brought a spare battery this time, otherwise he didn't know how to end it, personal disgrace is a small matter, and the lives of hundreds of officers and soldiers are in his own thoughts. Although the environment for the use of the robot this time is completely beyond the design specifications, this incident still gave Duke a deep lesson, that is, for the quality control and testing of the product, no matter how much it is worthwhile, especially for the research of weapons, the environment used is not as ideal as expected, and I have to consider the performance in various extreme conditions in the future.

Otherwise, once faced with today's special environment, if you don't think about the difficulties when you set off, it will really become a bloody lesson

In the heartless cheers of the officers and soldiers at the scene, no one thought that this extremely successful deep-sea rescue in the eyes of the officers and soldiers gave Duke a great touch, so that the quality of military products after DSM became the top level in the world's weapons, and became the most reliable reliance of the PLA in the Quartet.
