First of all, the servo valve is a device that can accurately control the flow and direction of hydraulic or pneumatic pressure according to the input signal. It is usually composed of electro-hydraulic servo valve or pneumatic servo valve, and is widely used in systems that need high-precision motion control. Compared with ordinary valves, servo valves have the advantages of fast response, high precision and strong adjustability, so they become the key components of robots to perform complex actions.

　　Secondly, the robot realizes the coordination of the servo valve through the central control system (such as PLC or embedded controller). This process  usually includes sensor data acquisition, path planning, feedback control and other links. For example, in a six-axis industrial robot, each joint may be equipped with a servo motor and a servo valve. The robot obtains the current posture and stress state through encoder and force sensor, and then the controller calculates the driving force required by each joint according to the target trajectory, and sends the control signal to the corresponding servo valve.



Finally, the coordination of robot to servo valve depends on the support of closed-loop control system. Closed-loop control adjusts the working state of servo valve by constantly comparing the error between actual output and expected value, so as to realize accurate control. For example, when carrying heavy objects, the robot will dynamically adjust the opening of the servo valve according to the load change, thus maintaining the stability and safety of the movement. In addition, modern robots may also use advanced algorithms such as PID control, fuzzy control or neural network to optimize the response characteristics of servo valves.



To sum up, the robot can coordinate the servo valve efficiently through precise sensing system, efficient control algorithm and stable closed-loop mechanism, so as to realize high-precision and high-efficiency automatic operation. In the future, with the further integration of artificial intelligence and hydraulic control technology, the ability of robot to coordinate servo valves will be continuously improved, which will inject new impetus into the development of intelligent manufacturing.
