High-speed and High-performance Controller

Is it humans who direct the work of robots? No, it's the controller. The industrial robot controller mainly controls the movement position, posture and trajectory of the robot in the workspace, the operation sequence and the time of action, etc.

The controller is the "decision-making body" that issues commands and is the brain of an automated factory. Taking control of the controller is equivalent to controlling the performance of the robot. In China, the controller market share of the four major families is 53%, among which FanUC accounts for 16%, KUKA 14%, and ABB Robotics 12%. However, the market share of domestic brand controllers is less than 16%, which shows that in the field of controllers in China, the degree of domestic production is relatively low.

At present, the domestic controller market mainly has the following problems:

1.  Domestic controllers can control a wide range of robot types, but there is still much room for improvement in terms of operational accuracy, stability, response speed, and ease of use.

2. The binding effect between the robot body and its components is strong. Generally, mature robot enterprises can achieve independent research and development and control of the robot body and core components. Therefore, domestic enterprises that only produce controllers find it difficult to break through.

3. Domestic controllers offer high cost performance, which is both an advantage and a disadvantage. The advantage lies in their ability to capture the mid-to-low-end market and emerging fields where the precision requirements for robots are not high. The main disadvantage lies in the fact that for the market, there is still a long way to go.

For this reason, the "Robot Development Plan" particularly emphasizes that through the development of high-performance joint servo, vibration suppression technology, dynamic inertia compensation technology, multi-joint high-precision motion calculation and planning, and other technologies, the motion accuracy in high-speed variable load application processes can be improved, and dynamic performance can be enhanced. Develop and master the technology of open controller software development platform to enhance the scalability, portability and reliability of robot controllers.
