Chapter 57 Six-axis Robotic Arm

The reason why it can do so many things is that the fourth-generation PenMaster handwriting robot has a 24-hour continuous working control accuracy of an astonishing 0.02-0.04mm!

This accuracy seems to be much worse than the 0.01-0.02mm accuracy of the robotic arms boasted on the Internet, but in fact it crushes the robotic arms boasted on the Internet.

Because in fact, although the Internet boasts that their robotic arms can achieve an accuracy of 0.01-0.02mm, that is repeated positioning accuracy, not absolute accuracy.

In terms of repeatability, the fourth-generation handwriting robot is also at the top level, reaching ±0.01mm.

But there is no point in bragging about the repeatability of positioning accuracy, because many customers often find out that they have been cheated after buying the product.

Lin Feng had seen a case in his previous life where the customer required an assembly accuracy of 0.05mm. The robot arm's repeatability accuracy reached 0.1mm~0.2mm, which seemed to perfectly meet the requirements.

When they were actually put into operation, it was found that they were completely unqualified. The error between them often reached 0.1mm to 1mm depending on the strength of the manufacturer, which did not meet the requirement of 0.05mm assembly accuracy at all.

So even though the robotic arm seems simple, any university graduate can develop and design a simple robotic arm by himself.

But in reality, it is very difficult to make a robotic arm that has ultra-high precision, long life and durability.

The reason why this thing is so difficult is not that the hardware materials of the robotic arm do not meet the requirements.

Of course, hardware materials are partly to blame, but the problem of poor control accuracy can be solved by using software to simulate actions and perform calculations to compensate.

But the problem is that calculating compensation accuracy through software simulation actions has stumped many people. This is also the point that determines the strength of a company's core technology, and this is the most difficult thing to solve.

After all, there are bound to be errors in the production of each robotic arm. The accumulation of multiple small errors will affect the final working accuracy. It is naturally difficult to achieve ideal accuracy.

What is even more fatal is that the machine parts have the problem of thermal expansion and contraction. As the machine continues to work, the heat and parts will definitely expand, and the accuracy will become even worse. This is the famous accuracy drift phenomenon.

Faced with many problems, the only solution at this time is to use software to simulate and compensate for processing errors to achieve higher precision.

So many people have the ability to develop robotic arms, but it is actually very difficult to do it well and accurately.

It can be said that if there were not many things that do not require such high control precision, it would be a question whether the robotic arm could develop.

At this time, the 24-hour control accuracy of the fourth-generation PenMaster handwriting robot can reach 0.02-0.04mm, which will definitely amaze experts around the world.

With the ultra-high absolute precision of 0.02-0.04mm, even though the size is small, the actual application scenarios are quite impressive.

It can be said that if this thing is slightly modified and sold as a multi-joint industrial robot, it will definitely sell like hot cakes.

Unfortunately, Lin Feng was not very confident about selling it, because this thing had too many application scenarios and the software was too easy to operate.

Finally, coupled with the ultra-fast working speed brought by the high-speed motor, it is definitely a favorite of countless factories.

By then, ordinary workers will be eliminated on a large scale, and Lin Feng will definitely become a damned guy in the eyes of countless workers around the world. How can Lin Feng continue to gain experience points?
So this thing is very good and powerful, but Lin Feng really doesn’t dare to sell it, and he doesn’t even dare to sell the fourth-generation handwriting robot.

After all, what if a hacker forcibly cracks Lin Feng’s control software and then modifies it for use in the field of industrial production?
Those unemployed workers and their families will certainly put the blame on him in the end, leaving him with no way to defend himself even if he had ten mouths.

Therefore, Lin Feng really didn't dare to mass-produce and sell this thing. He only dared to use it internally. At most, he would make a video to promote it, upgrade it, and then refuse to put it on the market on the grounds that the cost was too high.

"Let's put it away for now. Now is not the right time to research and modify it. Let's finish the recommendation algorithm first."

Lin Feng shook his head and packed the things and put them in a secret corner. In his laboratory, no one could open the door without a key, so he didn't have to worry about being discovered.

After hiding the fourth-generation PenMaster handwriting robot, Lin Feng sat back at his computer desk and continued the live broadcast. Later, he discovered that there were tens of thousands of people chatting in the live broadcast room.

At this time, they saw that Raymond Lam had suddenly started broadcasting, so they all greeted Raymond Lam and asked him various questions.

In response to this, Lin Feng spent a few minutes answering the questions, and then he continued to develop the recommendation algorithm.

During this work, Lin Feng discovered something wrong, which made him look slightly surprised.

Soon, Lin Feng suppressed the strangeness in his expression and turned off the live broadcast.

"I can actually consume 1000 source points to obtain the knowledge of the entire Douyin recommendation algorithm system. Isn't this too powerful?"

Although this recommendation algorithm is called an algorithm, it is actually a complete set of recommendation algorithm programs. The algorithm contained in this program is not just a recommendation algorithm, but is composed of multiple algorithms.

However, program development is not a simple task. According to Lin Feng’s estimate, the entire process will take at least two or three months to complete.

This is also the reason why Lin Feng has spent so much time and has not yet developed a recommendation algorithm program.

"In that case, what are you waiting for?"

After Lin Feng controlled his consciousness and clicked OK, the 1000 source points were suddenly cleared, and then new knowledge was instilled into Lin Feng's mind.

Still using the familiar coding and commenting habits, Lin Feng once again confirmed that this was the recommendation algorithm program he developed himself.

The only difference is that compared with previous product upgrades, this time the knowledge was directly instilled into his mind, and he had to type out code one by one.

In addition, because the instilled knowledge will never be forgotten, Lin Feng can then directly copy the code mindlessly.

From now on, you don’t have to think carefully about what code to use here and what code to use there, you don’t need to modify it repeatedly to find bugs, you can just mindlessly copy the code in your mind.

After this mindless copying, Lin Feng is confident that within 10 days, he can replicate the complete recommendation algorithm based on the original half of the work completed, and then officially start testing!
……

On the other hand, after obtaining a series of design and production drawings and software control systems for the second-generation coin-fired electromagnetic rifle, the Ordnance Industry immediately started trial production.

Although they do not have a dedicated winding machine, Lin Feng's production drawings also include production drawings of tools for auxiliary winding, which can be produced to assist in winding coils.

So it only took four days for the weapons industry to successfully produce the first batch of 500 coin-fired electromagnetic rifles, fully demonstrating how terrifying the weapons industry's production capacity is when it gets serious.

Subsequently, the sales department of the weapons industry began to look for sales channels for the coin-fired electromagnetic rifle, and eventually the first batch of buyers were determined to be police stations in Daxia and various countries.

After all, they are the ones who have the most urgent needs, and only they have the opportunity to use coin-fired electromagnetic rifles extensively in their daily work.

During this period, the sales team of the weapons industry naturally dispatched people to follow the police, hoping to shoot videos of them enforcing the law in preparation for the subsequent publicity.

Naturally, they had no objection to this, and within a few days, a storm that swept the Internet began.
