It can assist or even replace humans to complete dangerous, heavy, and complex tasks, improve work efficiency and quality, serve human life, and expand or extend the scope of human activities and capabilities. Robots have diverse functions and are gradually becoming intelligent. With the development of science and technology, robots are now gradually becoming an important tool in people's lives and work, and robots also have important uses in the service industry. Many of the upper parts of existing robots have functions such as rotation and pitch. However, there are some problems: the rotation function and the pitch function are respectively realized by the rotation mechanism and the pitch mechanism, which are too complicated in structure, and the structural space is very tight. The transmission structure components are prone to mutual interference, which affects the normal use of the intelligent robot. Summary of the invention
