Mixed In the United States As a Local Tyrant

In March, An Feng changed his job direction.

Colin Hoffman, the R\u0026D director of the robot company, obviously did not disappoint him. In just a few months, the second-generation exoskeleton has already taken shape. After all, that is the task of the third generation, and now the main focus is on the second generation.

Hoffman's work is concentrated on the upper body part. According to An Feng's plan, this is 50% of the overall work. The beginning is the most difficult. I thought it would take half a year, but this silent guy has repeatedly refreshed An Feng's understanding of human geniuses. The understanding of this guy-this guy's brains are so good!

Even if An Feng did it himself, he didn't have the patience to test it dozens or hundreds of times.

Hoffman, on the other hand, enjoyed the process.

If he was like a normal person in life, it would be very pleasing, but unfortunately things can't be perfect, except for professional content, Hoffman is just a nerd with a super long nerve reflex arc, boring gourd and doesn't understand life.

In order to speed up the research and development, An Feng joined the research work. To his credit, this was one of the few instances where he was willing to actively participate in the work.

Unlike the previous graphene and cancer cells, it is his ideal to have an exoskeleton and a few robot pets who understand human nature. When other things stabilized, he became a standard office worker, sending his wife to school every day, going to work at nine o'clock, and returning home at three o'clock in the afternoon...and so on for two weeks.

In addition to exoskeletons, the company has also set up research groups such as bionic machines, pet machines, and flying machines. Although the speed of exoskeletons is the fastest, other groups are not slow to make progress under An Feng's tips or guidance. Recently he received a new toy: a quadrotor horizontal coaxial aircraft.

It is the size of two palms, has four center-symmetrical rotors, can accept wireless commands, is equipped with a high-energy battery specially customized by GP Energy, and can fly for five hours. Record video up to 2TB.

The control terminal can be applied to a variety of devices, which is equivalent to a multi-platform APP, which can be used on mobile phones and tablets. The control is just like playing games, just tap your finger, but it requires a certain bandwidth to receive video images. When you are far away from the signal tower, you can only downgrade to SD video.

An Feng is now using the tablet to control the aircraft, and the content of the tablet shows the scenery outside the robot company - in the air. Not HD, but the zoom is good enough for him to make out the text on street signs, or the license plate number of a vehicle. Switch modes, and you can also record and take high-definition pictures at the same time.

Click, a car passing by the robot company was photographed, the driver was enjoying picking his nose, with a weird expression, An Feng retched a few times, and deleted the high-definition picture... Sometimes, these are too powerful Technology is not a good thing, it is beautiful to be able to ignore it.

An Feng controlled the aircraft to fly farther. Its controllable radius is about 3 kilometers, and its ceiling is 300 meters. When the aircraft floated to the fifth floor of an office building, he found a man bending over his desk. Busy girl, standard skirt and uniform, round buttocks.

"Hey, I found a beautiful woman!" An Feng laughed, but the disadvantage is that it can't make a sound, nor can it project text, otherwise it can tease the beautiful woman. He put down the tablet and recorded the defects on the side. Both voice and projected text are necessary, and information can be transmitted when it is critical.

Looking at the beautiful women was not the intention. After recording the defects, An Feng controlled the aircraft to turn back.

"The flying speed is still too slow." An Feng muttered, the camera captured Hoffman who was scratching his head, and the aircraft shook in front of him to show its existence.

Hoffman looked up, then lowered his head and wrote on the paper. The paper stood up, and it read: Can't collect sound, it will always be a half-finished product!

"Bastard!" An Feng scolded with a smile, letting the aircraft team know that the results of their hard work are evaluated in this way, and see if they will hit you with a sack at night.

Hoffman went on to write: The power feedback of the arm is in trouble.

An Feng raised his hand to look at his watch, he was about to leave work, but if he refused, this guy would have to struggle all night... An Feng let the aircraft land, picked up his suit jacket, put it on, and ran downstairs to the warehouse. The converted warehouse has become the general base of Hoffman and his "robot army".

The second-generation robot arm is indeed finished, but there are some problems with force feedback.

For example, when shooting a gun, holding the pistol with one hand and firing, the arm will be forced backwards. If it is in a normal state, An Feng's strength is enough to offset the recoil and keep the muzzle stable. But when wearing an exoskeleton, the computer mistook the backward force for a body movement and responded quickly.

As a result, after firing a shot, the arm movement will make the muzzle point to the sky, which is very exaggerated.

An Feng and Hoffman have to overcome the difficulties at present, which means that they need to design more dense sensors to collect muscle movements, feed them back to the computer thousands of times per second, and let the computer quickly judge which movements are autonomous, What is involuntary, and then give accurate feedback.

Hoffman said: "I tried all the silicon chips. The calculation speed can keep up, but the energy consumption is too high; control the energy consumption, but the calculation will not work."

"Silicon technology doesn't work, so let's use GP's experimental product." An Feng said.

Hoffman nodded: "This is a good direction!"

Fortunately, they have good innate conditions, have a sufficiently powerful graphene computer, and have sufficient super batteries. They only need to work hard on information feedback, and sooner or later they will solve it... After several days of research, the newly designed chip was added to the exoskeleton arm, An Feng put it on again.

In order to reduce weight, the material of the exoskeleton is made of carbon fiber or aerospace alloy as much as possible, which requires lightness while maintaining firmness. He sat quietly while two technicians fitted him with exoskeleton arms. Now this exoskeleton is very dexterous. It mainly has a hydraulic and electronic hybrid booster system, which is the key to strength. Of course, there are also booster systems on the small arms and fingers.

Just the machine that is attached to his right hand has more than twenty sets of power assist systems, the largest is the exoskeleton that simulates the human triceps and biceps, it is powerful; and the smallest is five. Fingers, the extension and flexion of each finger is provided with corresponding assistance.

This means that no matter what the action is, even picking the nose, the effort is only one-third, or even one-tenth of the original.

It took ten minutes to complete the installation. The system energy is provided by the battery pack on the back. The battery is not ordinary. It is specially made by GP Energy. The machine works more than 30 hours.

Hoffman took a few steps back and said, "It's ready for the actual wear test."

An Feng stood up slowly. Since he didn't have all the exoskeleton equipment, he felt that the weight was on his right hand. It was not too heavy, although it was quite big. Because he was willing to spend a lot of money, the total weight was only a little over three kilograms. Feng tried to raise his arm, and this time the feedback was very sensitive.

"It feels...better than last time, and the feedback is faster." An Feng said, judging with the naked eye alone, it is impossible to tell the difference, and only through wearing can one feel the subtle changes. An Feng took a few steps. The usual practice is the heavy object session, a 50kg iron box.

This time there is no iron hook, relying entirely on five fingers and biceps. The fingers lightly touch the grip, with a little effort, the fingers are tightly closed together, with only half of the usual strength, the grip is already tight, and then lifted up - no pressure. He changed his movements, straightened his arms, and lifted heavy objects flat-this extremely tested the computer's feedback speed, but it was still fast.

An Feng said without breathing, "It feels like it's only about ten kilograms."

"Come more complex moves," Hoffman said.

An Feng's next challenge: an inflated balloon. Wearing an exoskeleton to play with balloons is completely opposite to normal, the computer feedback power is slightly increased, and the balloons will explode. Last time, more than a dozen exploded... An Feng carefully touched the balloon, opened his palm to grab it, gently Pick it up lightly.

An Feng looked at the balloon in his hand that remained in its original shape, and heaved a sigh of relief.

"The data is very good! Let's have some brisk movements!" Hoffman recorded on the computer. The other researchers have different expressions, after all, there is only one set of models.

It is the suit worn by the boss. Because it is tailor-made, the length of the arm and the length of the finger are all the data of Anfeng, and others cannot wear it. Therefore, its success or failure is related to the future of the machine, including millions of Is the research and development cost a waste of money or a grand slam.

An Feng obviously also had full confidence in this set of expensive arms. He grabbed the balloon and slapped it upwards—the first time, the balloon lifted into the air easily. It still didn't explode, so he threw it again, and then grabbed it with other very awkward movements... After doing this more than a dozen times, the most sensitive details were not wrong, and the balloon was still safe and sound in his hand.

It was obvious that Hoffman also breathed a sigh of relief: "Very good! The computer data are all within the error value!"

"Come to the next test."

The firearms session was specially requested by An Feng, and a small underground shooting range was specially opened for this purpose—because San Jose’s regional laws are very strict on firearms management, they can only act in a low-key manner as required. In the underground shooting range, An Feng loaded a Glock pistol.

Raise your hand, aim the muzzle at the target ten meters away and fire until the entire magazine is emptied. The high-speed camera records every movement of him. The 10,000-frame camera means that it can decompose the bullets sprayed out of the gun chamber, Super slow motion of gas and flames spreading around.

In these slow motions, the swing of An Feng's arms was kept to a minimum, and the recoil of the firearm tried to affect An Feng's movements, but the sensors and the sensitive computer finally cooperated closely this time, allowing every voluntary movement to be fed back , involuntary is ignored.

The researchers had joy written all over their faces, and they knew what it meant.

After An Feng emptied the magazine, he skillfully unloaded the empty magazine and exclaimed: "It's so powerful, I feel that this machine is the same as my own arm, and I can't tell whether it's me or the machine that's working. It has been greatly improved, and it is already a success!"

An Feng has information in his head, so he knows what is success and what is a semi-finished product.

It feels right this time! After the left arm is finished, the spine and the legs are done next—they are much easier than the arms, so the arms take up 50% of the workload. As long as the difficulties of the arms are overcome, the future work can be done by analogy. At most it takes time.

After full completion, a beggar version of Iron Man with bones and no armor will be available.
