While controlling the demonstration, Lu An briefly introduced the remote operation: "To make the robot move, click and hold it and it will continue to walk. Double-click and hold it and it will continue to run. At the same time, turn the direction keys, and it will change the direction accordingly. In fact, it is exactly the same as controlling a character in a game." Sometimes you need to run faster, sometimes you need to run slower. "
Hearing this, Lu An smiled and said: "The speed can be adjusted, and it can be adjusted through these two keys."
He pointed to the two buttons on the upper right side of the remote control, which are marked by the two letters "A" and "M", which are the first letters of the words "acceleration" and "deceleration".
Lu An introduced: "For example, how do you want the robot to run faster? Double-click the movement direction button and hold it down. To accelerate, hold down the A button at the same time. Hold down the A button and it will continue to accelerate until it reaches the fastest design speed. Release the A button and the current speed will remain unchanged." It will maintain the current speed. When the direction key is released, it will quickly decelerate and stop moving." After speaking, Lu An demonstrated it on the spot. Under his control, the robot first walked in the hall, then ran, and then accelerated. However, the indoor space was not large, so Lu An did not let the robot run too fast, and it only ran in circles. He tried it in a small area and then stopped.
Li Fengting was shocked but also suddenly realized that the maneuverability and flexibility once again exceeded his expectations. It was hard for him to imagine that this was still a half-finished product in Lu An's eyes.
After a while, Li Fengting looked at the other four buttons on the right side of the remote control handle and asked: "What are the functions of these buttons?"
Lu An introduced them one by one and answered: "This is the attack button designed. Currently, the robot is designed for fighting. Of course, it can be adjusted and redesigned according to needs in the future. No. 1 The key is for hand attack, the No. 2 key is for leg attack, the No. 3 key is for jumping, and the No. 4 key is for squatting. "
"Just think of it as an arcade fighting game. I designed it according to the thinking of the fighting game "The King of Fighters". These four attack keys, single pressing key 1 or 2, are conventional hand or leg attacks."
"But there are many rich attack methods. Due to the limited space on the remote control handle, we cannot design too many buttons. If there are too many buttons, it is easy to press the wrong button."
"In this case, the solution is to make the robot have a variety of combination attacks, just like the combo design of "The King of Fighters". Press the corresponding order to launch the corresponding attack method."
“For example, the left and right +1 button is a left hook, the right +1 button is a right uppercut, the up +1 button is an uppercut, the left and right +1 buttons are an elbow strike, and then the left and right +2 buttons can be followed by a knee kick, etc.”
“Through this combination key design, the robot can perform a variety of combination attacks, and the operator can perform combos as long as he memorizes them.”
Lu An obviously designed it based on the operation method of the classic game "The King of Fighters", and it can even be said that he copied it. Because this mode is really easy to use, there is no better way to control the controller than the solution designed in the "King of Fighters" game. This is the near-optimal solution to the remote control method.
If each attack method had to correspond to a button, even the buttons on a keyboard would not be enough, let alone a handheld remote controller with smaller space.
But it is still different from the "King of Fighters" game. For example, the four attack buttons of King of Fighters are hand light attack, leg light attack, hand heavy attack and leg heavy attack.
The keys 3 and 4 of the remote control designed by Lu An are for jumping and crouching. The jumping in the game "The King of Fighters" is directly realized by using the direction keys. The up direction key is for jumping, and the down direction key is for squatting, because this game is a horizontal version.
But the robot is in a real three-dimensional space, and the degree of freedom is one more dimension than the horizontal version of the game, so jumping and crouching require a separate button design, and there is no need to distinguish between light attacks and heavy attacks.
Lu An smiled and said: "At present, in the remote operation mode, the robot's attack methods are relatively simple and limited, and there is not much polish. However, as long as you spend time, you can add more attack methods. Of course, it is also related to the strength of the material. The higher the strength, the more abundant attack methods can be designed."
Li Fengting was amazed and said: "It is incredible to be able to achieve this level. It is incredible that such a large body has such flexibility and high balance."
If applied to the battlefield, these close combat attacks are of little use. The main thing is to allow the robot to hold and use guns, a function that robots do not yet have.
However, after seeing Lu An’s demonstration operation with his own eyes, Li Fengting believed that he could definitely solve the technical problem of letting the robot attack with a gun.
At this moment, Li Fengting was shocked and surprised at the same time.
This time he came to Lu An with the intention of asking him face to face whether he could build a robot with human-machine collaboration.
In the end, he didn’t expect that he had already finished it, let alone that the maturity level was so high. He never expected that such a high level of maturity would still be a semi-finished product in Lu An’s eyes.
In other words, there is still huge room for improvement. How could this not surprise him?
Li Fengting asked: "Comrade Lu An, what are the differences, advantages and disadvantages of these two control modes?"
Hearing this, Lu An replied: "It is true that each has its own advantages and disadvantages. Let's talk about the remote control mode first. Its advantages are low cost and small space occupied, but its disadvantages are relatively complex operations and weak battlefield situation awareness." The two are completely synchronized. The disadvantage is that the cost is higher and the operator takes up more space." Li Fengting nodded, then looked at Lu An and said excitedly: "The purpose of my visit this time is to ask you if you can make such a humanoid robot, but I didn't expect you to give me such a big surprise, and you have already made it."
Lu An couldn't help but smile when he heard this. He was also quite surprised. He originally thought that after making the robot, he would shoot a few videos and share them online to attract the attention of the military.
Now I feel relieved because the military has come to visit me personally.
After a while, Lu An invited the two of them to the living room on the second floor to sit down and talk in detail.
Meng Qiuyan poured a few glasses of water and a plate of fruit over to simply receive him. Of course, there was expensive tea. Although soldiers were not public servants, they were still state workers and it was not appropriate to entertain them with too high a standard.
Li Fengting said: "Comrade Lu An, I think you have probably guessed that I came here on behalf of the military to ask if it is possible to develop an armed robot with human-machine collaboration. Since you have produced such a highly complete physical object, the military must make substantial progress."
"After I go back to report this time, the military will most likely launch a new military research project, which is your armed humanoid robot with human-machine collaboration."
"This project must be led by you. It will be left to you and Metaverse Intelligent Control to overcome the difficulties. Depending on the completion of your robot, I believe that the project will be approved before long."
