my country’s current industryRobotThe status quo, in four words: strong demand, overheated industry, blind following, disorderly development. There are about 4,000 Robot companies in China, and only 2,000 of them are on-body robots. There are only 5 well-known industrial robots in the world after 40 years of development. Of the 2,000 robot manufacturers in China, I think 90% of them were either acquired by others or died in the middle.
2. A country with strong quality, concentrate on making flexible industrial robots
Foreign robots are still dominant in China. Why do we still have a gap with foreign countries?The key to the robot is to control themotorThere is an encoder behind the motor, which is fed back to control its activity, so if there is an error in the motor, it can be overcome.
Behind the motor is the RV gear, this error is not incontrollerwithin. So if we want to do a good job in a robot, we must first do a good job of the motor and controller, and complete the error correction of the feedback part. In this semi-open loop situation, only by improving the accuracy of the ramp gear can the accuracy of your robot be improved. , which is why we say that simply making a simple ontology cannot improve the ability of the robot. Due to our processing and manufacturing, the level of craftsmanship and control is limited, which makes Japan and Germany stuck in our necks.
Therefore, if we make industrial robots according to this line of thinking, we must do five things well.The first is to do the ROS gear, the harmonic gear and the controller at the end, and the most important thing is to do the controller; the second is to do the RV gear; the third is to do the harmonic gear; the fourth is to do a good jobservo motorDo it well; fifth, do the system well. If these things are done well, our industrial robots will have the opportunity to PK with foreign countries.
3. Find a new way to develop high-rise buildingssmart robot
do it differentlyrobotHow to do it? To be an intelligent robot, it should be done according to the principle of human work.
What is the difference between human work and robot work?
To achieve precision in human workmanship, it is necessary to look at it while doing it to form an intelligent feedback loop, adjust the position of the workpiece and the position of the tool, give feedback through the eyes, and then do it through the judgment of the brain.But nowIndustrial robotIt didn’t do it, the security machine did it. Therefore, it is necessary to increase the intelligence of the machine, reduce the dependence on the accuracy of the components, and reduce the error of external environmental interference.
Two loops need to be added to be called an intelligent industrial robot. In the first cycle, a force sensor or a vision sensor is added to the end of the robot, and the force and vision sensors are used to give feedback to the work all the time, forming an intelligent closed loop. The second cycle is more about adding artificial intelligence.
