These are the basic principles.

Now it is all realized by imported devices. Domestic inertial instruments have low precision and high price, so they can't compete with foreign countries unless they are banned.

In these fields of precision instruments, the gap between China's top products and western industrialized countries is at least two or three orders of magnitude. Those papers, scientific and technological achievements, medals, certificates, professional titles and academic qualifications are all aimed at scaring the people. The top management knows very well that no matter how much money is invested, there is no improvement. Only Deng Xiaoping first publicly disclosed the facts. The gap between us and the advanced level in the world is getting bigger and bigger.

From the high-energy physics, deep space exploration and cutting-edge weapons and equipment at the forefront of world science and technology, we can know the key to high-performance instruments.

For wheelchair climbing stairs, ordinary tilt sensors can be used, and equipment ranging from one yuan to 3,000 yuan can meet the requirements.

For wheelchair climbing stairs, it is a piece of cake to measure the current posture and movement, but it is the main difficulty to maintain the human body's load-bearing posture through electromechanical devices. With the domestic consumption level and the performance of steel and aluminum profiles, the devices made are too heavy, too expensive and too big, and the corridors are crowded with motorized wheelchairs.

There are so many people who want to make money through this device that no one can achieve it.

As for exoskeleton boosters and exoskeleton robots carrying people to climb stairs, it is even more hopeless.

Let's use electricity. A joint RV reducer is 654.38+0,000 yuan to 50,000 yuan, excluding the motor. If it's made in China, it's big, heavy, slow and of no commercial value.

An exoskeleton booster needs at least 8 joints. How to calculate this account! !

Using hydraulic pressure is more expensive! ! Even the pipes, joints and electrically controlled valves are completely dependent on imports!

So the key to the above problems is the industrial base, people's consumption level, as well as those management diplomas, artistic accomplishment and so on. It happened that those hooligans were fooling the public.

You should stop thinking about it and do something practical. It's important to make money to make a living.

If they can do it, Peking University, Tsinghua, Huazhong University of Science and Technology, National University of Defense Technology and Harbin Military Industry have already done it.

People know more about how high the threshold is and where the limits of their abilities are.

The domestic counterfeit two-wheeled balanced electric vehicle "Segway" can be mass-produced, and the number of customers is indeed limited.

The device you are looking for is easy to manufacture.

As for this kind of device driven by crawler and wheel set, it has been produced abroad for many years, and it can also be mass-produced in western industrialized countries.

Now the starting price of the product is 30,000 RMB, 80,000 RMB is normal, and 300,000 RMB is reasonable.

Domestic consumption cannot afford it.

Countless people at the bottom of society are looking forward to getting rich with thousands of dollars.

National Machinery Research Institute, Machinery Research Institute, and large enterprises that produce CNC machine tools have long been overused! ! !

So, not long ago, I saw a post that Baidu knew about the website.

Users show that they have a CNC machining center that can be used freely.

Q: What level of skilled workers should be employed to manufacture micro turbojet engines and micro turbofan engines?

You should rush up! ! ! ! !

On the surface, design is a very simple thing.

Firstly, the computer simulation of dynamics is carried out, relying on imported software.

Then there is the computer simulation of structural optimization design, and there are also imported software, which can know in advance where the stress is concentrated, to be reinforced and so on.

Then, the computer simulation of the transmission mechanism can be imported into the software to see whether there is motion interference between components and whether the motion is smooth. After analysis on the computer, the data file of parts processing is automatically generated, and manufacturing is started in the NC machining center.

Hire several postdoctoral and master's degree teams. Didn't China set up a large aircraft design company with private investment in recent years?

This is a mature path and process in the world.

If you throw money, you will get results! Go to seize the market and open up business opportunities! ! !
