Create Param(object) Class
Create init(self) function
Create ROS timer and designate callback
After creating client1, specify global_costmap of move_base Node in dynamic_reconfigure Client
After creating client2, specify local_costmap of move_base Node in dynamic_reconfigure Client
Create call_back(self, timer) function
Update the parameters of client1 to {“footprint”: [], “robot_radius”: 0.2}
Update the parameters of client2 to {“footprint”: [], “robot_radius”: 0.2}
Timer and ROS shutdown
rospy.init_node('costmap_dy_rc', anonymous=True)
param = Param()
rospy.spin()
Create costmap_dy_rc Node
Assign Param() Class to param variable
