At present, with the application scope of various manipulators becoming wider and wider, the production processing and production lines in many workshops are gradually choosing equipment to replace manual repetitive work. Therefore, at this stage, truss manipulators have become the automatic equipment that mainly replaces manual work in the automatic production line of many parts and other products, Let's take a look at the advantages of the truss manipulator in the process of taking the place of workers: a. The multi degree of freedom of the truss manipulator: the truss manipulator has the advantage of working at any angle, which is often called the degree of freedom, which means that the manipulator can act at any angle within a certain range, This advantage has also become that truss manipulators can meet the production and manufacturing needs of more refined commodities, and also because of the advantages of multi degree of freedom work, truss manipulators can be used in the workshops of many high-precision parts manufacturers. b.
