1. Parameter server model

Parameter server in ROS It is mainly used to realize data sharing between different nodes . The parameter server is then equivalent to a common container independent of all nodes , You can store data in this container , Called by different nodes , Of course, different nodes can also store data , The typical application scenarios of the parameter server are as follows :

Path planning , It is necessary to refer to the size of the trolley , We can store these size information in the parameter server , Global path planning nodes and local path planning nodes can middle note these parameters from the parameter server.

Parameter server , It is generally applicable to some application scenarios with data sharing .
