FANUC industrial robots are used more and more widely. However, robots’ communicant protocol and interface are different and unopened. Robot interface technology has become an important factor. Controlling robot movement via interfere has become an important issue in recent years.NI LabVIEW has powerful data acquisition and measurement ability and friendly graphics programming interface. It has the most percentages in the field of automatic measurement. The interface between PC and FANUC industrial robot is studied. A serial of sub VI are developed based on LabVIEW, including connecting robot with PC, initializing robot interface, reading and changing system variables, reading and changing position variables, displaying current position, controlling robot programs and so on. This paper describes the hardware and software components of the system, and the typical communicant and control module between PC and FANUC robot developed by LabVIEW. After testing, the function of every module can be achieved and performs well.
