Zhang Rui is quite the opposite and somewhat disappointed, but it is even more pleasantly surprised. After all, in the “entrepreneurial boom†promoted by China’s current capital, we see more of the “stars†eager to paint the cake and flocked for billions of dollars in financing. However, few pragmatic and hard-working people are seen.
Prior to starting the business, Zhang Rui worked successively in the Beihang drone institute, the Institute of Automation of the Chinese Academy of Sciences and the China Space Academy, and participated in some scientific research projects. However, each work was short-lived. Zhang Rui said that he has been looking for something that can be done for a long time.
Soon, he eyeed the biped robot.
In Zhang Rui's opinion, even if the R&D of the robot seems to have made breakthrough progress, it still has a long way to go compared to the ultimate goal. However, can robot entrepreneurship survive? He was very calm about this because he saw a blank.
For a long time, as foreign countries started early in the field of robotics and their core technical barriers are high, domestic universities and research institutes want to study it, either by purchasing it from abroad or developing it by themselves. The former spends huge sums of money, and the latter often quits because students graduate. This has led to the fact that both academic and industrial robots are unable to form a strength that can be compared with foreign countries.
Therefore, from the very beginning, Zhang Rui and his Iron Man Technology wanted to take the lead in applying R&D robots to universities, research institutes, and science and technology museums to serve their research, education, and display. This will also enable "phased commercialization" to ensure that the company has sufficient funds to operate and bring benefits to investors.
Find opportunities in segmentsZhang Rui may not be the first to notice this blank, but in this subdivided field, only he has actually made products and has the possibility of commercialization.
In fact, to trace back, the history of humans making "robots" may be as long as 500 years. In the 16th century, artificial humanoid monks appeared in churches, and the clergymen used them to "reappear" Bible stories. Until 1921, the scene in Prague was called "Rossum's Universal Robots," a sci-fi drama by author Karel Chapcek who invented the "Robot" term (which we are now familiar with) as the "new species". Named.
Time passes, human beings have made great progress in the manufacture of robots, and the definition of robots is changing. Zhang Rui believes that, from a broad perspective, the robot is an unmanned system. It includes devices such as drones, unmanned vehicles, and unmanned boats that automatically perform work, as well as various types of intelligence developed through bionic and human-like methods. Mechanical device; from a narrow sense, the robot specifically refers to the latter.
According to the application environment, experts in the field of robotics in China classify it into industrial robots and special robots. Industrial robots refer to multi-joint robots or multi-degree-of-freedom robots that are oriented toward the industrial sector, while special robots are robots used in non-manufacturing industries and serving humans in addition to industrial robots.
The two-foot big humanoid robot that Zhang Rui focuses on is a type of service robot in a special robot.
In the eyes of ordinary people, robots appear to be a black technology, but the basic principles are not difficult to understand. Russell made the simplest explanation in "artificial intelligence - a modern method". Although he is talking about a comprehensive "wisdom body", robots are also the same principle:
The robot senses the environment through the sensor and the control center represented by the “question mark†conveys the sensed information to the actuator, and the actuator responds accordingly. In fact, the nature of human behavior is very similar to human nature. Human vision, touch, and taste are equivalent to sensors. A “question mark†is equivalent to the brain and an extremity is an actuator.
The irony of Iron Man is to solve this question mark.
Self-designed R&D hardware and "sports brain"
According to reports, humanoid robots are mainly human in three aspects, namely form, behavior and thinking. No matter from which aspect, designing a successful humanoid robot is very difficult, and there are three difficulties:
The humanoid robot itself is a precision optical-electromechanical integration system, which is full of uncertain challenges in design, production, and assembly.
It is very difficult for the robot to learn to walk and adapt to various types of terrain. The control and coordination of hands, brains, and feet is very difficult, and there are high requirements for algorithms and systems.
It is most difficult for the robot to have the ability to make decisions autonomously, know what kind of movements it wants to make, and even have its own personality.
The first thing that needs to be solved is the morphological problem. This involves a large number of sensors in the hardware. However, the existing modules on the world do not meet the requirements, either because the price is expensive or the accuracy is not enough. Iron Man Technology independently designs and develops according to the structure of the robot itself, one to reduce costs and the other to achieve internationally leading quality.
In the second generation of robots assembled at the beginning of 2017, Iron Man Technology put two Intel processors, one of which was specifically responsible for the robot's motion balance control system, and the other for macro planning of brain decisions.
Therefore, in terms of freedom, Iron Man's ART robot has six degrees of freedom on one leg, twelve degrees of freedom on two legs, two degrees of freedom on the ankle joint, and three degrees of freedom on the hip joint, which allows the robot to walk. Similar to human gestures.
With hardware not enough, Zhang Rui and his Iron Man Technology have developed a set of motion control systems called "sports brain." The sports brain is a set of decision-making systems based on the robot's morphology, using positive inverse kinematics, dynamics, and artificial intelligence techniques to allow robots to have autonomous athletic ability.
"Sports Brain" has three levels:
Level 1: Joint Control
At the joints, information such as the rotational position, speed, acceleration, and torque of each joint needs to be collected, and then the MCU drive motor of each degree of freedom is used for precise control.
Second level: neural control
According to the robot's posture, force and moment, vision and other information, the robot's gait under various scenarios is controlled.
Level 3: Task Level Control
When a command is given directly to the robot, such as finding a person at the meeting, the robot may need to turn the camera and find the person. This is the highest level decision.
According to Zhang Rui, Iron Man Technology provides two things, one is the hardware itself of the robot, and the other is the development environment. In order to allow more customers to directly use the robot, they package the sports brain and the user can directly call it.
Currently Iron Man Technology has completed the assembly of the second generation of products and is also about to complete a larger amount of A round of financing. Domestic scientific research institutes and universities led by academician Li Deyi of the Chinese Academy of Engineering have all paid great attention to Iron Man Technology, and believe that this is in line with Zhang Rui's “early heartâ€.
