Problems solved by technology
[0002] With the development of modern science and technology, robot technology has been widely used in various fields. Most robots are equipped with multi-degree-of-freedom mechanical arms, which can complete the required work through expected actions. Nowadays, most of the mechanical arm joints are one joint. The degree of freedom, driven by a motor, can only realize the deflection of one orientation, and to achieve multiple degrees of freedom, it can only be realized by connecting multiple joints in series. This method will inevitably increase the overall structural size of the applied manipulator , thus increasing the space and weight of the manipulator, and in some special applications, the structure of the manipulator is required to be as simple as possible and flexible, and this type of structure will be subject to certain restrictions
[0003] In addition, the applied mechanical arm joints cannot be easily increased or decreased by adding or reducing joints after the design is completed, so as to achieve the increase or decrease of its degrees of freedom, in order to deal with some special application occasions

The invention discloses a wire transmission type universal ball joint. Through the use of the cross universal joint and reasonable structural cooperation, one joint and multiple degrees of freedom can be realized. This joint can make the structure of the mechanical arm more compact, The overall size and weight of the robot arm are reduced, but the flexibility is greatly increased; the universal ball joint provided by the invention realizes the modularization of the joint through a simple structure, and can easily increase the number of joints in the robot arm, thereby increasing the mechanical arm. Flexibility: The universal ball joint provided by the present invention has strong versatility, and can be applied to mechanical arms in various occasions, so as to complete many tasks that cannot be realized by conventional mechanical arm structures.
