The development of robots has begun in the 3rd century BC. Today, it has penetrated into different industries and fields, and has also begun to be subdivided into welding robots, spray robots, and medical robots. In recent years, collaborative robots have also begun to develop gradually.
  In observing several stages of robot development, we can see that the demand for robots is constantly changing.
At the beginning of the development of robots, industrial robots may be a product needed for automation transformation, so it has not even achieved a unified global product standard. In the second stage, the characteristics of product globalization have been very obvious, the types of structures have been relatively stable, and the shape of the structure has also tended to be basically based on 6-axis, 4-axis palletizing, and Scara. The application industry is also relatively concentrated, most of which are concentrated in the automotive industry.
In the third stage, the application of the industry is more and more subdivided and more differentiated. Under the premise that its product structure tends to stabilize, the development trend of hardware has converged, most of the computing power is sufficient, and the application software is very rich, and various functional modules can be developed for different application scenarios.
  The robotics industry is currently in the third stage. In the fourth stage of evolution in the future, some artificial intelligence applications, such as neural network algorithms, will be added, which will gradually make the use of robots more and more intelligent.
But what kind of collaborative robot does the demand side want? Integrators actually have more concerns:

1. It can be a general-purpose robot, especially parts and components;
2. There is no pressure to stock up;
3. The installation is simple, it can be installed without a lot of heavy equipment;
4. There are fewer requirements for commissioning engineers;
5. The cost and profit margin of integrators is greater.
6. What end users want is more:
7. The number of product generations is stable and the investment pressure is small;
8. Low maintenance cost;
9. Safe and small footprint.
  Therefore, most companies are beginning to consider whether robots can do it according to user needs. Different end users want multi-purpose and mobile stations, remote control, simple programming, no professionalism, safety, low capital cost, and deployment time. Low, the production line of switching products can be reused, reducing the cost of end users.
  Therefore, collaborative robots have launched a new round of automation development, and gradually began to be more different from traditional industrial robots.
  Specifically, compared with industrial robots and collaborative robots, there is still a gap. For example, compared with the scara robot, the Scara robot has a relatively small working radius and a relatively large amount of programming. It is suitable for three-joint rapid rotation, general-purpose automation equipment, and relatively one-time investment. Big. Compared with collaborative robots, parallel robots have a higher programming threshold. They are mainly used for sorting and have a faster speed, but there are some limitations, such as programming, light-load, and mobile stations. Some of the more common ones, for example, may be used in welding, spraying, processing, grinding, polishing, inspection and other application fields, but many manufacturers have their own programming languages, and industrial robots have relatively high programming thresholds and require training.
  From the perspective of the industrial robot software system, it is roughly divided into three major parts:
  The first part is the core algorithm. Such as the control of kinematics and dynamics, the perception of force.
  The second part is function realization. It is the functional application of the industry, such as welding, palletizing, spraying, and polishing.
  The third part is software-based things that make applications more convenient, such as human-computer interaction, 3D simulation, and the use of other supporting software.
  In this regard, established industrial robot companies are committed to developing software and algorithms to make the use of industrial robots more convenient and easier. Therefore, most industrial robot companies have made three changes:
  The first one is to do independent research and development in the control system from hardware, to software, to algorithms;
  The second is to develop industrial application software packages for more industries;
  The third is to develop 3D offline simulation software and offline programming system.
  After continuously expanding the field of industrial robots, it has also done so in the industrial field:
       1.The absolute path remains stronger. For industrial robots, one thing that is extremely demanding is the requirement for trajectory accuracy. Actually, our robots often teach at low speeds when teaching, and they may deviate from the original taught trajectory at high speeds, so it is necessary The trajectory can be kept consistent at low speed and high speed.
  2.Fast trajectory generation with higher trajectory accuracy. For example, when a robot can target three or even four workstations, as long as the trajectory of one of the workstations is taught, the trajectory of the other three workstations can be obtained by translation or rotation. This is beneficial An algorithm for rapid deployment of robots and rapid production.
  3.Mainstream processes such as welding are more abundant. The ever-expanding industrial robot package has formed core areas that cannot be completed or replaced by collaborative robots such as die-casting, bending, grinding, palletizing, and seam tracking, and at the same time enriches the functions of each industrial field.
  But on the other hand, some fields do require human-machine cooperation, because most of the time industrial robots do need some fences, and the one-time production line investment cost is also relatively high.
  In addition to some specific occasions where collaborative robots need to use industry, Scara, etc., there are also some specific occasions that require collaboration and human-computer interaction. Collaborative robots can be used as some human-computer interaction polishing, spraying, and polishing. There are also some human-machine cooperative handling, as well as smaller areas. For example, some palletizing companies also need to reduce the floor area, and the collaborative robot can also make some changes with a small area because the collaborative robot itself is small and safe. , It can occupy a small area and does not need a man-machine partition, and the needs of these scenarios will have collaborative robots.
  At the same time, the application of collaborative robots in the 3C industry has also proved its effectiveness. The 3C industry is like dispensing electronic products. The end of collaborative robots is equipped with a vision. Most traditional enterprises have a person working at the front end. People need to assemble the front end and the back end flows through the assembly line. The robot can complete the grasping. Glue, identification and positioning. The main problem is that the robot and the human can only be close to each other with a gap of less than 1 meter. There will also be human operations or robot operations. This requires a flexible robot, and the electronics industry needs more floor space. Small, so it is necessary to make a smaller station.
  There is also the assembly of electronic equipment, and collaborative robots are also more compatible. Collaborative robots and humans can be made into human-machine collaboration on the production line, or can be made into mobile stations, which can be switched when a certain station is needed, and can be pushed at any time. At the same time, two hours of debugging can be used immediately on the production line, which is extremely efficient.
  Therefore, most of the collaborative robots are innovating according to the needs of users. Most companies are committed to the development of wireless teaching, graphical programming technology, visual security protection and other technologies, and gradually gain advantages. There are also some drag teaching technology, integrated joint technology, collision protection technology, robot control technology, high-precision joint servo control technology, force control technology, and collaborative robots are also forming their own technical advantages.
  From the perspective of market data, the domestic robot market is still gradually growing. Domestic robots were only 150 million yuan in 2015, but by 2019, the data of all companies have doubled, basically making more than 4 billion yuan. The collaborative robots will exceed 10 billion in 2025. In 2017, collaborative robots accounted for 4% of the total robots. From the data growth trend alone, it is expected to account for 34% in 2025. This growth is a double growth. . From 2014 to 2017, the demand for collaborative robots also accounted for 15% and 22% of the global scale, and the demand is increasing.
Generally speaking, robots are still very much-needed products. Industrial robots and collaborative robots each have their own advantages. As long as they can maximize the strengths of their respective fields and find suitable customers, growth is still not a problem in a stable market environment.
