China is the first country to break through the bottleneck of "mechanical exoskeleton". Will high-simulation intelligent robots be fake?
The brand-new concept product "Exoskeleton" that has appeared before can also be called exoskeleton robot, power exoskeleton or mechanical exoskeleton.
It is a power machine attached to the outside of the human body. When wearing a mechanical exoskeleton, it can increase the body's endurance, strength, protection or support.
The new "exoskeleton" concept has been high hopes. It has a huge market and prospects in military, medical, civilian and other fields.
But after so many years, due to some technical problems, there is still no stable exoskeleton technology widely produced and applied in the world. Huge market vacancies and regrets are left.
Because of the existing exoskeleton technology, its control and power systems mainly receive control commands through sensors, Controlled by computer-aided calculation, and then powered by hydraulic system or electrical system to achieve the effect of exoskeleton amplification.
In order to promote exoskeleton on a large scale, the exoskeleton must be a self-sufficient power and energy system.
Power and energy are the fatal problems of exoskeleton. At the same time, it is difficult to solve the battery size, weight, capacity and replenishment in a short time using technology. The effects of control and power systems are directly related to thresholds and costs. The high price, maintenance and maintenance costs are also the limitations of exoskeleton technology.
Last year, a young man in China applied for a special exoskeleton Invention patent, which was just announced this year. This is a new dynamic method proposed for the current situation of dynamic exoskeleton, "Elastic weight-bearing exoskeleton"
The bones give up external power supply methods, such as electric motors or hydraulics. The creative use of "weight rebound" is combined with the concept of exoskeleton. The exoskeleton invented-"the heavier the weight, the more power The stronger".
Elastic loading Principle:
1 represents the human body and load-bearing objects, 2 represents the spring, and 3 represents the support frame of the exoskeleton.
Its power principle is: the body maintains the weight up and down The inertia of the spring. When the weight bounces upwards, the weight of the exoskeleton is the lightest. When the weight springs downwards, the weight of the exoskeleton is the heaviest. So (4 in the picture) move forward in the weight-bounce state, ( As shown in the figure 5) The exoskeleton supports the weight when the weight is lowered. People only need to maintain the bounce effect of the weight and follow the weight to bounce up and downThe rhythm is moving forward. Can control the exoskeleton to move forward.
I have to admire the wisdom of our people, which has plagued the "power energy" problem of exoskeleton development for so long. It was solved with this simplest and stable power method.
This special power mode exoskeleton also has special advantages.
Strong weight bearing effect:Its upper limit of weight is very high, because all the weight is borne by the supporting structure of the exoskeleton, including the body's own weight, and people do not need to support any weight.
Strong kinetic energy and endurance: It is powered by the elasticity of weight. The heavier the load-bearing object, the greater the elastic potential energy of the exoskeleton, and the stronger the kinetic energy. And people only need to maintain the weight of the bounce effect and follow the steps of bounce inertia control, which saves much energy.
No need to supplement energy, light and stable structure: Since it does not have an external power supply system, there is no need to carry external energy, power supply systems, computers, sensors and other electronic equipment. Its structure is also very light and stable.
Extremely low cost: The price of dynamic exoskeleton is as high as hundreds of thousands to hundredsCompared with ten thousand dollars, the cost of elastic exoskeleton is very low, and the low price can even be used by the whole army and crush all similar technologies.
Low technical threshold: Because it is a pure mechanical structure and does not require particularly precise parts, the technical threshold is very low.
Safe and reliable: This kind of exoskeleton has no external power and relies on its own body weight. It is very safe and reliable and can be easily used for civilian use.
Mature technology: Compared with the dynamic exoskeleton which is still in the exploration stage, the simple mechanical structure of the elastic load-bearing exoskeleton is very stable. This is only half of the design success. As long as R&D funds are in place, you will soon see Even has been sold.
But civilian use can only play half of its effect. If used for military purposes, it can perfectly play the most powerful load-bearing capacity and maneuverability of this technology. It allows people to carry more Powerful weapons, armor and supplies. Such a low cost allows exoskeletons to be used on a large scale in the army. The platform nature of exoskeletons was originally designed to match various weapon loads and defense armor.
At the same time, it can also be used as a platform for human-computer interaction,Medical gait rehabilitation tools, special weight-bearing transportation tools......
This is the latest "exoskeleton" technology, and the patent has just been announced. Before long, this technology will pull the "exoskeleton" from the altar of science and technology, into various fields, and into thousands of households.
It’s a genius design. No one dares to imagine that the "exoskeleton" can carry weight effectively without an external force system. Without the madman's dedication, one would never dare to take this dead end. Without a heavenly idea, it would be impossible to design this invention.
The combination of genius and lunatic created a new exoskeleton technology.
The era of elastic loading of exoskeleton is not far away.
