Research and analysis of humanoid robot simulation

In order to highly fit the needs of humanoid robots in the development and acquisition of leading products, the concept of a systemic development is necessary to be upgraded to a guiding principle. In the United States and Japan, the research and development of the current humanoid or simulation robot has reached some simulation experiments of perfect human behavior, The leading American robot with fully electro-mechanical design in structure is a pack of intelligent automatic metal of simulated human body, but an outstanding problem is that the weight proportion reaches twice times of real human being, Others misleading need not to mention; only this alone makes it impossible to enter the common family and society. Its positive aspects are only designed as a carrier for AI development tests and as a primary design experience for the accumulation of simulation knowledge of bipedal humanoid robot. Japan's most advanced simulation robot is different for the body skeleton that using full resin material and driven by the American McKibben pneumatic muscle invented in the 50's, of last century, the purpose can be seen in their research and development in the direction of deduction weight. The comparison here I would like to show is that the United States has developed a humanoid machine or “Iron Man”. Japan has developed a machine-core style of human. In this way, Japan is leading in materials and construction design. There what it can not be complimented is that Japan's power source is a compressed air station in external, that is obviously in the preliminary test phase. In addition, McKibben pneumatic muscle is large in size, and also low in mechanical efficiency, the self-friction loss comes from structural design, it also make air noise and work under very high air pressure, so the product still need theoretical breakthrough and fundamental modification. The patent of "elastomer hydraulic muscle" developed by China's Development Institute> has made innovative development for overcome existing shortcomings of “Mckibben air muscle”. First, the volume is reduced in diameter, the length and shrinkage ratio is greatly improved and there is no self-friction. The working pressure is also reduced and thus more secure, and the noise source is only one motor. A mechanical analysis of McKibben pneumatic muscle have introduced in the appendix of the article named of "humanoid robot design and manufacturing", for reading one may search Baidu Library by the name of jessy508. In order to promote the development of humanoid robot, the author's intention is to share some ideas here. The following are specific statements under sub-headings:

1. The reference and orientation of humanoid robot development:

Since the research object is humanoid robot, the ideal final product must be infinitely close to the natural human being. Referring to the blueprint of a natural human and its astonishing action and folding function we will find out a direction. The development of non-metallic elastomer hydraulic muscles will meet the requirements of lightweight and space-intensive and to get many benefits (not absolutely excluding metallic materials), At present we have more than four different variety of “elastomeric hydraulic muscles” , all designed under reference of human body function, structure and characteristics of non-living material.

2. Materials for constructing humanoid robots:

Firstly the materials for production of humanoid robot, in principle, considering the strength of the body structure and the ideal type of robot product keep weight proportion at 1.5 will be more easily to achieve. The body skeleton is the main structure of the resin-based materials, the purpose is to be large-scale injection molding, the joints using rubber and polyurethane type which can be cast molding, The aim is to obtain the elastic energy storage required for limb movement reduction or go back, which is a followed design by the use of Elastomer Hydraulic Muscles. Elastomer hydraulic muscle and human skeletal muscle force of common characteristics are only tensile, so the elastic joint reduction design will reduce the use of the elastomeric hydraulic muscle (This does not have to imitate the human skeletal muscle distribution and a pull back muscle). The connection between the elastomeric hydraulic muscles and the hydraulic driven pump is solved with a single nylon tube, this still due to the use of elastomeric hydraulic muscles; The diameter of the elastomeric hydraulic muscle is retracted to match the elastic joint resilience to reset the limb and simultaneously send the pressure medium back to the hydraulic pump through the nylon single tube. The diameter of the elastomeric hydraulic muscle is retracted to match the elastic joint resilience to reset the limb and simultaneously send the pressure medium back to the hydraulic pump through the nylon single tube. So as the design is the weight of such human robots has been reduced. In this way, from the point of view of automatic electronic control, only the drive pump can be controlled, and other practical fiber reinforced hoses can replace the nylon single tube and apply external force to control the fluid to be throttled or closed. In summary, the emphasis on the weight principle has forced a completely unconventional drive system structure to come in light, while solving energy consumption and sensitivity problems, etc., and significantly reducing manufacturing and maintenance costs. In short, the light weight and simple structure are great.

3. Hydraulic drive system for humanoid robots:

The hydraulic drive system of humanoid robots should adopt a single-motor multi-pump multi-stage output method with multiple integration schemes; mechanical variable control design can be added to obtain complex robot body actions, such as pressure relief or energy storage devices in pipelines, auxiliary attachment variable devices and so on. The specific solution combines a selected matrix capsule or a plunger pump with a servo drive. The limbs can be divided into four units to control independently to achieve asymmetric and complex behaviors of robot motion. The main research and development part of reducing weight and energy consumption lies in energy-consuming devices. The combination of preferred materials and simplified structural design not only achieves better anthropomorphic effects, but also simplifies the intelligent design requirements and costs, creating what is not based on all existing achievements is the starting point for creation; yet what we need is a collection of multidisciplinary and multicultural models. The most valuable ability to generate does not simply begin with calculations, especially from intangible to tangible modeling thinking as a result of knowledge and association. However, the realization of industrialized mass production and enterprise standardization must not leave the laboratory's data collection and mass production process research, which is the main component of the pre-production development workload, and can also be recognized as real-time workload. The design strategy of the relative product structure type requires the creative thinking. To accomplish this task, only one brain and several assistants can be used in human resources. This must be a brain with long-term rich professional accumulation, a brain that knows the end result in the face of initial development.

4. Humanoid function and AI system:

As far as any mechanical design is concerned; the modeling thinking of physical and mechanical structures is the result of associative ability. The connotation of a high-value design must include its own rationality and historically proven reliability, simple and versatile function of components are a must-have goal, so the necessary functions for lightweight preconditions are available with energy savings and low cost. In addition, the overall design of the humanoid robot must lay a good foundation for AI and electronic control; its content includes simple and reliable control, accurate repeat positioning, long-term operation accuracy and human-machine friendly quality. At present, the level of intelligent control of AI level has advanced; the development of human-computer interaction level, detection and sensing, intelligent identification and deep development of machine self-learning system are still to be developed. Optimistically speaking; the combination of technology research and successful results sharing in human society made the development of this direction already progressing with each passing day. It is okay to give such questions that should be get together in humanoid robot to the capital.

5. Selection and relay based on principles of research and development:

The humanoid robots that mark the progress of science and technology in our era will inevitably constitute the vast market. Follow-up of this epoch-making initiative should not leave the inheritance and development of existing technological achievements, so the specific design scheme needs mature basis and reference. Of course, this is contradictory to the creation of new against old, and it is necessary to study the project with rigorous speculation and criticism. The combination of rigid materials and elastic polymer materials required for the development of humanoid robots has a wide range or space , and there are few predecessors involved. In this respect, nature provided us with inexhaustible models, Nouns such as humanoid, bionic, and simulated robots also include the meaning of to learn from nature. So studying and drawing on the creation of nature is an important way.

The research and development of science and technology is the act of human beings to create object. Because natural people can't grasp enough continuous huge energy like universe, even the life of our individual is very short, we have to make up for it with the rationality of cultural education and pass it on from generation to generation, even carefully. It is the basic reason for why culture and science education originated in human society. What we get today is the science and culture in the macroscopic and microscopic exploration of the two poles of the universe. But the social needs are the interests; the real needs of human being for survival. In the development stage of human society today, this kind of object is called commodity, such a pair of contradictions raise the issue of cost and product lead and service life for R&D personnel. Therefore, R&D tasks are naturally required to be highly in-depth and reliable, so that long-term leadership is likely to continue to develop.

Here we may wish to regard the universe as the main body of creation. The solar system is a system full of energy that is complete and has everything. The earth is a workshop. Then everything in the world or earth is the product assembled in this workshop. The only difference or marvellous is the intelligent human being at the high end. Obviously, the original products on the earth are not designed and planed. Is there really not? There is, but in different forms, the study of natural history of the universe by human science is looking for them. The results found are the natural theorem, the law of particle motion and the force of energy. This is some of the production tools of the original earth workshop. The original creation is unmistakable and omnipresent. The assembly cycle is calculated in tens of billions of years. Its countless microscopic products are unrecognizable. We can only see the natural adapters but not those disappeared or deceased. The number of the deceased is even more unknown.

Human R&D and manufacturing are different; we don't have the volume, time and energy of the first three mentioned above. Then rationality and culture have arisen, to know how this process is; then wait for generations! Big data will give us a better answer.

Back to the proposition of creation; the great works and perfection created by heaven have left us examples and sets of rules. The problem have to be studied is here; the objective law must be referenced and observed, and subjective cognition is the true law if it conforms to the heavenly principle, otherwise it is the anti-reason. The consciousness of creation and motivation and ability are partly derived from the “inner self”. It is an endowment. The ego is the appearance of the growth of the “inner self”. The difference of the ego is the social load full of variables and the constituent elements of the creative team. Super-ego is the stage of personality that human beings use for research and creation, and it is also related to the problem that a group and a nation are at what steps of human social development. So you don't have to be daring to know from whom or where the real humanoid simulation intelligent robot will come from.

So far, the article deals with two creative ontology in the universe; one is the original of the universe, and the other is the human being who relays the original and realizes the reality of creation through rationality and culture. if the universe does not shrink and broken, the future of human beings is bright. But this does not prove that we are safe; science and culture are oriented towards wonderful ideals and the future, but commodities bring about depletion of resources, degeneration of human nature and deterioration of the environment. Therefore, the products we need to develop most are humanistic ethics. Human society and life will be highly integrated with artificial intelligence robots, which will surely produce a high proportion of materialized society, acceptable, ethical, fair, and sustainable future world, will be what a problem we have to study of .
