Script-based industrial robot programming system capable of achieving secondary development

The invention discloses a script-based industrial robot programming system capable of achieving secondary development. The script-based industrial robot programming system comprises the steps that a definition system sets data, and basic data types and instruction sets are defined in a system script file; instruction sets and data types of secondary development are defined in a user script file, a script-based secondary development module is applied, the module can customize instructions and data according to the requirement of a user, the instructions customized by the user are a combination of the system instruction sets of in the step I, and the data types customized by the user are a combination of the system basic data types in the step I; and robot programming is carried out through a teaching box, and motion control of a robot is achieved. According to the script-based industrial robot programming system, the instruction sets of the user requirement are secondarily developed in a script manner, the programming language has high flexibility, the special instruction sets can be set according to the requirement to meet specific application requirements, and the system has the advantage that code reediting and programming do not need to be carried out for development of new instructions.
