At present, there is an increasing demand for intelligent functions such as machine vision and autonomous path planning in industrial robots. However, adding intelligent function modules in the traditional industrial robot systems requires a lot of source code modification, wasting manpower and cost. An easy-to-extend robot system development platform based on ROS presented in this paper provides developers with the convenience of developing intelligent industrial robotic systems. The platform is divided into server-side and robot-side. The robot-side as a first-level node, communicates with the server-side installed with the ROS. The first-level node of the robot consists of the second-level functional nodes and functional modules. According to this platform, the JPB06 6-DOF industrial robot system has intelligent function modules, such as machine vision, autonomous positioning and voice control, which can meet the needs of industrial robots for intelligent and real-time control.
