Application and technical problems of "parallel robot"

As an important member of the robot family, parallel robots are used in 4D sports theaters, aircraft driving simulators, space docking simulation equipment for two aircraft in space, large earthquake simulation platforms, micro-nano operation robots, etc. These devices have one thing in common: strong carrying capacity, high control accuracy, and high rigidity, which are the most outstanding excellent characteristics of parallel robots. Although parallel robots have so many qualities, it can be seen from the appearance that these "robots" can clearly feel that their mechanisms are generally more complex, with more branches and hinges. In fact, the design process of parallel robots is not a pleasant thing. How to design robots according to the functional requirements of parallel robot products has been a hot and difficult topic in international research in the past 20 years. What kind of robot, how many branches and hinges are included, how long the parts are, and how to arrange them are all current problems. After research and experiments, the research team proposed the concept and definition of GF set that expresses the terminal characteristics of parallel robots, and established a theoretical system for the topological design system of parallel robot mechanisms.
