Collaborative robot, as the name suggests, is a kind of robot that can interact with humans in a close distance and cooperate in a common working space. As a rising star of the industrial robot family, collaborative robots combine the efficiency of robots and human intelligence, and their pioneering working mode and wide range of application fields have opened a new era for the development of industrial robots. Compared with traditional industrial robots, collaborative robots break the restrictions that can only be applied to industrial scenes, and also have broad application prospects in commercial and service industry scenarios such as medical care, education and training, and new retail.

Due to the ease of use, flexibility and security features of collaborative robots and outstanding cost advantages, the market growth rate has been leading the industry in recent years. Globally, collaborative robots have shown explosive growth since 2016, with a compound growth rate of more than 40%. At the same time, the Chinese market has gradually become one of the engines of global collaborative robot growth, and the number of collaborative robot companies exceeds half of the world. Using artificial intelligence, sensing intelligence and control intelligence technologies, a number of new forces in the field of Chinese robotics are thriving and making history.

Recently, focusing on the field of intelligent motion control, Action Yuan (Shanghai) Technology Co., LTD. (hereinafter referred to as “Action Yuan”) announced that it relies on the digital twin platform and integrates intelligent algorithms to launch intelligent motion control solutions developed for collaborative robots, which have excellent control performance and outstanding cost-effective advantages comparable to the international leading level.

New journey

Mobile yuan helps China’s collaborative robot field to overtake on corners

Motion control system is one of the key components of cooperative robot, which plays a crucial role in the ease of use, safety and flexibility of cooperative robot. The newly launched motion control solution of Mobile unit, with high-performance ring drive as the core, integrates sensing, driving, braking and transmission for the integrated compact joint module, fully meeting the requirements of precision, flexibility and integration of collaborative robots.

Mobile unit high-performance circular DC servo drive solution is the first of its kind in the domestic product performance comparable to the international leader, to enjoy patent protection of the ring design as the feature, to rival the international leading products of excellent performance, rich functions and good ease of use as the core, superposition professional and efficient localization technical support services and excellent cost performance. It is expected to break the passive situation of long-term dependence on imports of cutting-edge compact joint module intelligent motion control unit at one stroke, and help China’s relevant industries quickly enter the C position on the world competition stage.

The hollow design of mobile intelligent ring driver makes the wiring more convenient, reduces the size of the driver, is easy to integrate, can realize the integration of joint parts, and greatly saves the installation space; At the same time, the advanced intelligent algorithm is used to optimize the control performance of the driver in high-precision motion, so that multiple loops are in the same level of collaborative processing, compared with the traditional PID design, the gain parameters are simplified, the gain control and stability are automatically optimized, and the setting time is shorter. Mobile intelligent ring driver EtherCAT refresh frequency can reach 4kHz; Using Sigma-Delta sampling mode, the current accuracy can reach 16 bits; And with one key setting, torque compensation, friction compensation, vibration suppression and other features of practical functions.

In addition, the supply cycle of similar foreign products is often more than half a year, which is the biggest problem encountered by customers in the past, and this problem is also solved with the efficient delivery service brought by the strong local R & D and production team. At the same time, in order to effectively improve the installation and use efficiency of customers, mobile Yuan has set up a local technical support team covering North, South and East China to provide customers with real-time assistance, virtual model testing and big data feedback testing, so that customers’ use efficiency has been greatly improved. It is worth mentioning that through the innovative research and development model and the lean grinding of all aspects, the mobile unit will greatly reduce the cost of the ring drive that was originally rare and expensive, and more robot enterprises will benefit from it.
