Analysis of core components of industrial robots in China

The industrial robot industry chain can be divided into the upper, middle and lower reaches, and the upstream is the key component manufacturers, mainly the reducer, control system and servo system. The middle reaches are the robot body, that is, the base and the actuator, including the arm and the wrist. The sub-robot body also includes the walking structure, which is the mechanical tradition and support foundation of the robot. Only after the system is integrated can the produced robots be put into the downstream automotive, electronics, metal processing and other industries for use by end customers.

 

Overall, the total cost of industrial robots is close to 70% of core components, with reducers, servo motors and controllers accounting for 32%, 22% and 12% respectively. Specifically, the controller consists of hardware design, low-level software technology and upper-level functional application software, which is equivalent to the "brain" of the robot; the servo system is mainly servo motor, which is equivalent to the "neural system" of the robot; the reducer is The areas with the highest technical barriers are often installed at the joints of the movement.
