The Parameters Server is an essential component of the Robot Operating System (ROS) that allows nodes to read and write parameters. Parameters can be used to configure the behavior of a node or the entire system.

Basic Usage

Parameters: Parameters are key-value pairs that can be set at runtime or at startup.
Accessing Parameters: Nodes can access parameters using the get_param and set_param functions.
Types of Parameters: Parameters can be of different types such as strings, integers, booleans, and more.

Example

#include <ros/ros.h>

int main(int argc, char **argv)
{
  ros::init(argc, argv, "parameters_node");

  // Set a parameter
  ros::param::set("robot_name", "ROSbot");

  // Get a parameter
  std::string robot_name;
  ros::param::get("robot_name", robot_name);

  ROS_INFO("The robot's name is %s", robot_name.c_str());

  return 0;
}
