Buzhou mountain, 11th floor.


    Qin Jian forms a circle with a group of engineers. Among them is a prototype of a small unmanned vehicle.


    The car is 50cm long, 50cm wide and 50cm high. It looks like a cube as a whole. The four corners are marked with ABCD to distinguish the head area.


    Qin Jian''s right hand slid from left to right in the air in front of him, and then a projection screen was displayed in front of him, and everyone looked at it.


    At this time, the screen shows a 360 degree picture around the unmanned vehicle and a navigation map. There is a point flashing on the map. Qin Bamboo Slips click the flashing point.


    Then the vehicle sent out a "didi didi" sound, and a mechanical sound sounded: "the target is determined, the action route is being planned, the route planning is completed, ready to start."


    The vehicle immediately moved forward, but at this time, everyone formed a circle and surrounded it. The unmanned vehicle immediately stopped and moved along the inner circle.


    Chen Hao looked at the driveway: "I don''t know if he can go out."


    "I see no problem. We have written rules in this case."


    "Yes, it should be no problem."


    "Look, it stopped!"


    At this time, the unmanned car stopped in front of Qin Jian, and the mechanical voice said, "please make way for the handsome boy, thank you!"


    As soon as the unmanned car said this, the whole audience laughed.


    "OK, I know how to please the boss."


    "Boss, have you set it up specially, or how can you call it handsome."


    Qin Jian pushed back two steps, made way for the road, and then said with a smile: "yes, I recognized that I was a handsome man, ha ha ha!"


    At this time, an employee smiled and said, "boss, don''t be narcissistic. He calls everyone handsome."


    There was a burst of laughter at the scene.


    The unmanned car said, "thank you!"


    Then he ran out of the way made by Qin bamboo slips.


    Then the mechanical voice sounded: "I have detected the strange indoor environment. I am drawing an indoor map and looking for an exit."


    With the sound of machinery, the unmanned vehicle wandered around the room. At the same time, an indoor plane map was drawn with the trajectory of the unmanned vehicle.


    Now the unmanned vehicle is transmitting positioning sound waves to the surrounding through ultrasonic radar, and then drawing the current indoor map.


    The unmanned car ran around the room. The current map was drawn successfully. He found the gate, and then the car went out of the hall and into the corridor.


    At this time, one person in the crowd followed out, and the others continued to view through the projection screen.


    The 360 degree video allows them to see the current environment of the unmanned car. At the same time, an indoor map nearby is constantly improved. The unmanned car drives in the corridor and then enters the elevator.


    "Find the elevator and call the elevator."


    In corner a of the unmanned vehicle, a mechanical arm is raised. The mechanical arm is about two fingers thick, and the top is a three finger mechanical finger.


    The robot arm is raised high enough to press the down button.


    At this time, there was another burst of cheers in the hall.


    They stayed up all night for half a month to identify the elevator signs and call the elevator.


    The elevator arrived soon. The unmanned car entered the elevator, then pressed the first floor, and then retracted the manipulator.


    At this time, the man who entered the elevator leaned next to the unmanned car. When his leg was about to touch the unmanned car, the unmanned car moved and walked towards the other side of the elevator. At the same time, the mechanical voice sounded: "this handsome boy, please keep a safe distance from me, thank you!"


    There was another burst of joy in the hall.


    Qin Jian nodded. It seems that the behavior checking algorithm is well trained.


    When the elevator came to the first floor, the unmanned car got out of the elevator, then began to draw the indoor map of the first floor, and soon found the door to go out.


    Out of the gate, the unmanned vehicle stopped in front of the steps, and then stretched out four mechanical legs from the bottom to push the unmanned vehicle up. The four mechanical legs supported the unmanned vehicle down the stairs. When it came to the road, it immediately put away the mechanical legs and moved forward on wheels.


    At this time, some pedestrians on the roadside found the unmanned car with the word Qianxun sprayed on it. They looked at it curiously. It was the first time to see such a small unmanned car.


    Everyone in the hall is a little nervous. Now it''s the key moment to test the algorithm. Whether the unmanned car can safely reach the Kunlun building next door in the outdoor environment is related to their research results during this period of time.


    Qin Jian is not too nervous. He personally developed the core algorithm of the unmanned vehicle. He is very confident in the algorithm.


    After the unmanned car got to the road, the speed became faster and went to Kunlun Mountain next door along the pedestrian passage.


    The people in the hall looked at the images sent back by the unmanned car and various environmental information maps currently displayed, and their hanging hearts gradually relaxed.


    The unmanned car soon arrived at the Kunlun mountain building next door. After entering the hall, it began to draw the current map and then look for the elevator.


    After entering the elevator, the mechanical arm extended and pressed the 98th floor.


    At this time, several people in the elevator were taking the elevator. They looked at the unmanned car with some curiosity. In particular, the robot arm really looked like science fiction. A little sister wanted to reach out and touch it curiously.


    Miss, just reached into the air, the manipulator of the unmanned car shook, and then the mechanical voice sounded: "this beauty, please don''t touch me."


    The young lady stretched out her hand and hung it in the air. She was surprised and said, "Wow, this car is really interesting."


    She immediately took out her mobile phone and began to take photos of the unmanned car and send a circle of friends, "I met a very interesting unmanned car in the company."


    The people in the hall also saw this scene, and they all smiled.


    When the elevator stopped, my sister took a look at the unmanned car and took several photos before leaving until the elevator door closed.


    The elevator soon reached the 99th floor. After the unmanned car got out of the elevator, it began to draw the current indoor map, and then entered the corridor to the office hall on the 99th floor.


    At this time, many people found the unmanned car and immediately began to watch.


    The unmanned car slowly began to move forward. From time to time, there was a sound, "please let the handsome man off the road", or "please let the beautiful woman off the road."


    "Is this the latest product of the group?"


    "Not our group, but the big boss next door!"


    "This is to find the president!"


    "I think so."


    The unmanned car was moving forward hard in the crowd. At this time, in the hall, people could see clearly that a flickering dot was displayed on the indoor map, but the place was still not drawn on the map.


    At this time, a woman in a business suit came out, looked at the crowd and said loudly, "let''s stop looking. The president is waiting."


    The crowd dispersed, and the unmanned car immediately accelerated and moved towards the target.


    Women in professional clothes followed the unmanned car to the door of the president''s office, and then helped open the door.


    The unmanned car entered Dong Jing''s president''s office.


    Dong Jing is playing with a disc flashing red light. The whole disc emits silver metal light, and a five pointed star is engraved in the center. At this time, the red light is emitted from the star.


    This thing is called a star sign, which is specially used for positioning. Although mobile phones can locate through maps, in three-dimensional space, especially in high-rise buildings such as Kunlun Mountain, it is not planar, but three-dimensional. Unmanned cars can find the building through the map, but if you want to find a specific floor of the building, you need this star sign for auxiliary positioning.


    Through the star Mark, the unmanned vehicle can build a three-dimensional spatial coordinate, so as to accurately find the position of the star mark.


    Dong Jing looked at the unmanned car and said with a smile, "boss, this unmanned car is very fast!"


    Qin Jian''s voice sounded: "it''s still called fast. It''s been used next door for nearly 20 minutes. No, no, it has to be optimized."


    Dong Jing got up, picked up a pile of documents on the table, came to the UAV and said, "this is the report of the last quarter. I don''t know if I can fit it."


    Qin Jian''s voice sounded: "of course."


    Voice: the top cover of the unmanned vehicle is opened to the outside, revealing the inner space. There is a 40 * 40 cm space inside. There is no problem putting a pile of data.


    After Qin Jian put the data in, the top cover closed automatically.


    Then the unmanned car began to return.


    When I went there, because it was a strange environment, the unmanned car spent a lot of time drawing the map, but when I came back, it was very fast. It took less than 10 minutes to return to the 11th floor of Buzhou mountain.


    After Qin Bamboo Slips took the information out of the unmanned car, a burst of cheers broke out at the scene.


    "Boss, we succeeded!"


    "Great!"


    "Ha ha ha!"


    “……”


    Qin Jian is also very happy at this time. It has been nearly four months since the project was approved. The first prototype car has finally come out, and the technical team has grown up at this time.


    Zhang Hao said: "Boss, judging from the current data, we have basically reached our original goal, but the battery is a hard injury. After only one trip, the power consumption next door is 50%, which greatly limits the driving distance of unmanned vehicles. Under the current situation, unmanned vehicles can only run back and forth within 5km, beyond which there is a risk of power failure 。”


    Qin Jian nodded and said, "you''re right. The power consumption is really too large. We need to optimize this. You can communicate with Biya to see if they can provide batteries with higher density. In addition, we should speed up the research and development of public charging piles. Now we can only increase the endurance of unmanned vehicles by laying charging piles."


    At present, the battery used by Qin Jian is a high-density battery customized by bidi, a famous domestic battery manufacturer, to ensure that the battery can have more power under a fixed volume. At present, it seems that it can barely meet the requirements of unmanned vehicles. Qin Jian naturally has more high-end battery technology, but he doesn''t want to take it out now.


    Batteries are very important for scientific and technological products. Once new batteries with higher density appear, it means the upgrading of countless related industries. Mobile phones, electric vehicles, electric vehicles, UAVs and all kinds of scientific and technological products that need batteries will usher in great breakthroughs in performance. This is a technology that affects countless industries and can''t be taken out easily, Qin Bamboo Slips need a beginning and a transition time to give themselves and others a reason for technological breakthrough.


    Zhang Hao nodded and said, "OK."


    Qin Jian said with a smile: "it''s been a hard time for everyone. The success of the unmanned car test is inseparable from your efforts. I sincerely thank you here. I promised you to double the bonus before."


    "Wow ~ ~"


    "Thank you, boss, boss!"


    "Great!"


    “……”


    The crowd cheered.


    Qin Jian waved his hand, motioned for everyone to be quiet, and then said, "this time the internal test was successful, but it does not mean that the project was successful. We still need more test data and more actual scenes. Next, we need to carry out small-scale test. This workload will be very large. I hope you can have a psychological preparation."


    Chen Hao said loudly, "don''t worry, boss. We won''t let you down."


    Others echoed: "yes, yes, boss, rest assured, we will work hard!"


    Qin Jian said with satisfaction, "OK, let me talk about the task arrangement."


    The crowd stopped cheering and waited for Qin bamboo slips to command the task.


    Qin Jian looked around at the crowd: "at present, there are three important tasks to do,


    The first is to continue to optimize the algorithm, especially the rule algorithm, which still has a lot of room for improvement,


    Second, cooperate with restaurants within 5km around Buzhou mountain and Kunlun mountain to let them try to use unmanned cars for delivery, which requires everyone to sweep the streets in person,


    Third, it is a long-term process to conduct in-depth learning training on the data collected by unmanned vehicles. I hope you can make continuous efforts and don''t relax. "


    People have expressed their position and will work harder.
