(Summary description)　　Collaborative robots have only begun to gain widespread attention in recent years, but in fact the concept of collaborative robots was first proposed in the 1990s. As a new type of robot that has attracted much attention, collaborative robots have many advantages. In summary, there are four main ones: safety, low cost, flexibility, and easy-to-use methods. 　　It is predicted that collaborative robots will increase tenfold from 2015 to 2020, and their market value will rise from 95 million U.S. dollars in 2014 to 1 billion U.S. dollars, while lightweight robots will be popular within two years, with prices falling to 15,000 to 20,000. US dollars. Analyst company TechNavio predicts that by 2019, the compound annual growth rate of the high value of global collaborative robots will be 50.88%. 　　1. Three representatives-Japanese, European and domestic 　　Yaskawa: Human-machine collaborative robot MOTOMAN-HC10 　　These two problems generally exist in the method of human-machine cooperation safety setting in the market: one is to protect personal safety, which requires a safety grating, which increases the investment in equipment and costs; the other is the complexity of the operation, and unskilled personnel cannot control the robot.  　　To this end, Yaskawa Electric has launched the MOTOMAN-HC10 with the characteristics of "use immediately after setting" and "safe and convenient". All axes are equipped with force sensors, which will automatically stop working as soon as they touch the human body. The outer arm of the machine is wrapped with a blue soft material used to absorb collisions, which can completely realize the HC10 and the human work in the same space, without the need for safety barriers, saving costs. 　　Universal Robots: The world's first, UR5 robot     　　When it comes to representatives of the European department, Universal Robots is doing its part. UR5 can be said to be the first collaborative robot in the world, and it has been available since 2009. Human instructions can be understood only through sounds, gestures, and graphics; human-machine collaboration can be safely produced without obstructions, with super human perception performance; modular plugs and production parts, an integrated robot system that can be deployed in three days. 　　Xinsong: "Tai Chi" 7-joint robot     　　What factors determine the flexibility of industrial robots? As we all know, the most important factor is the number of axes. The number of robot axes determines its degree of freedom. The higher the degree of freedom, the closer the robot is to the motion functions of the human hand, and the better the versatility; but the more degrees of freedom and the more complex the structure, the higher the overall requirements for the robot. A contradiction in robot design. 　　This 7-axis flexible multi-joint robot can be said to be the first 7-DOF collaborative robot in China, with functions such as rapid configuration, traction teaching, visual guidance, and collision detection. If you are working in a small space and require repeated twists and turns of the robotic arm, this seven-axis robot will be a good choice. 　　2. Ultimate Profound meaning-product definition of collaborative robots 　　Flexibility 　　Compared with industrial robots on traditional large-scale production lines, collaborative robots need to cooperate with humans, and their structure size should be lighter, more flexible, and have more space for manipulation. 　　Ease of use 　　Collaborative robots emphasize ease of use. For example, they can be followed by sensory devices through gestures, lowering the barrier to use. Frontline workers may only need a few hours to operate, eliminating the need for complex programming and configuration of traditional industrial robots. 　　Safety 　　Collaborative robots are mainly used for human-machine collaboration, working with humans, must ensure safety, and cannot harm humans due to accidents. This has high requirements for the perception and control of collaborative robots. 　　Low cost 　　Collaborative robots are oriented to small and medium-sized enterprises, and the lowest possible cost is very important, but often the low cost and performance will also be reduced. It is relatively difficult to control the cost while improving the performance. 　　3. Indispensable-servo and sensor 　　For a collaborative robot to possess the above four characteristics, it must have the ability to sense, control and limit torque. By sensing the smallest external torque changes and reacting to avoid collisions, the process of human-machine collaboration is easier and safer. 　　(1) Ultra-small, powerful servo driver 　　The physical size of a driver is small enough to be directly mounted on the robot joint, which ensures that the robot is small in size and compact in structure. The servo driver is directly installed on the robot joint. Placing the driver close enough to the encoder feedback can save cables, reduce interference
