Application Cases
The joint module is used in many fields. On the automobile production line, it accurately controls the welding tools, and the multiple joints rotate flexibly to ensure that the welding points are even and firm, greatly improving the quality and efficiency of the body welding. In the 3C product assembly process, its gentle and precise movements can finely assemble tiny parts and reduce the defective rate. In the logistics warehouse, with the help of the robotic arm, the joints can flexibly adjust the grasping angle, quickly transport various types of goods, and adapt to packaging of different specifications. In the education and scientific research scenarios, it provides students with a practical operation platform to help learn robot technology. With its stable performance and high degree of freedom, the VJ-02 robot joint is broadening the boundaries of intelligence in multiple industries.
