Problems solved by technology

Although robots have strong flexibility in interacting with peripheral equipment, most of their operations are passive and repetitive tasks, which do not meet the needs of intelligent manufacturing. Therefore, intelligent equipment represented by industrial robots is an important part of realizing digital twins. However, the application of digital twins of industrial robots is rarely explored
[0004] In the existing technology, the control, monitoring and precision control of robots are often separate parts, which cannot be organically combined through digital twins
At the same time, the offline programming technology of industrial robots often needs to import executable files into the robot controller for operation, which is inefficient in production and response to product replacement and adjustment
As a result, information islands in robot production operations have also been created, and many data in the production cycle have not been effectively collected and stored
