Abstract: In order to resolve the limitations of private closed-end structure that be used by traditional control system of industrial robots, Using Windows NT system platform establishes an open architecture computer control system which towards to 6-DOF Articulated robots.It makes a system structure which be based on the operating system of Windows NT+RTX and hardware platform based on PC bus architecture, in order to face to the requirements of Industrial robot control system about real-time performance, scalability, maintainability, reliability.The system software uses a modular design principle, with a friendly graphical user interface that makes it easier to edit and the calling application program and the implementation of related actions.Through the analysis of test data, the system of high precision and high reliability is validated.
