Analysis on flexibility of industrial welding robots and simulation research

In this paper, the authors are analyze the work space of industrial welding robots by employing Monte Carlo methods (MC) and kinematical analysis, and provide a way to determine conveniently whether or not a hollow or cavity exists in the work space through simulation. By employing the concept of flexibility, flexibility ration and service sphere, the authors are also to analyze the flexibility of any point in the work space of the robots, and to obtain the flexible work space, which provides reference basis for the follow-up development of industrial welding robots in terms of improving their performance and the flexibility in the workspace.
