Mixed In the United States As a Local Tyrant

  Chapter 183 High-tech toys

  In March, An Feng changed his job direction.

Colin Hoffman, the R&D 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. Awareness—this guy's brains are too good to use!

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

   Hoffman enjoyed the process.

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

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

  Different from the previous graphene and cancer cells, it is his ideal to have an exoskeleton and several 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 established 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 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—aerial. 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, his expression was weird, An Feng retched a few times, and deleted the high-definition picture... Sometimes, these too powerful technologies It 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 beauty!" An Feng laughed, but the disadvantage is that it can't make a sound, and it can't project text, otherwise, you can tease the beauty. 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 beauty is not the intention. After recording the defects, An Feng controls the aircraft to turn back.

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

  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 fruits of hard work are evaluated in this way, and see if they will hit you with a sack at night.

  Hoffman continued: The arm's power feedback 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 is a problem with force feedback.

  For example, when shooting a gun, holding the pistol in 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.

   This leads to, 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, and 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 is not good enough, let's use GP's experimental product." An Feng said.

  Hoffman nodded: "This is a good direction!"

Fortunately, they have good innate conditions, have enough powerful graphene computers, and have sufficient super batteries. They only need to work **** information feedback, and sooner or later they will solve the problem... After several days of research, the newly designed chip was added to the exoskeleton arm, and the Feng wears it again.

  In order to reduce weight, the material of the exoskeleton should be made of carbon fiber or aerospace alloy as much as possible, which requires lightness and firmness at the same time. 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, "The actual wearing test is ready."

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 you feel it through subtle changes. An Feng took a few steps. The usual practice is the heavy object session, a 50kg iron box.

  There is no iron hook this time, 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 panting: "It feels like it's only about ten kilograms."

   "To more complex movements." Hoffman said.

  An Feng's next challenge is to fill the balloon with air. Wearing an exoskeleton to play with balloons is completely opposite to normal. The computer feedback force is slightly increased, and the balloons will explode. Last time, more than a dozen exploded... An Feng carefully touched the balloon, held it with open palm, and gently pick up.

  An Feng looked at the balloon in his hand and breathed 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 expense 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. If it didn't explode, 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 did not go 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 on 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 the San Jose area laws are very strict on gun control, 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 have joy written all over their faces, and they know what it means.

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.

  The feeling is 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. More time-consuming.

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