[ROS in 5 mins] 053 – How to load params on the Parameter Server

Written by Ruben Alves

Welcome to this “ROS In 5 Minutes” videos series.

In today’s video we are going to learn how to load parameters on the ROS Parameter Server.

But before we start, if you want to Learn ROS Fast, remember to take one of the following courses:

In the video we used the following commands to create the structure of our package:

mkdir ~/catkin_ws/src -p
cd ~/catkin_ws/src
catkin_create_pkg tutorial
cd tutorial/
mkdir config
touch config/params.yaml
mkdir launch
touch launch/load_params.launch

The content of our params.yaml is:

ros_learning: Robot Ignite Academy

The content of our load_params.launch we did not post here because YouTube does not accept “less than” and “greater than” symbols.

And the commands used to see our parameter was:
rosparam list | grep learn
rosparam get /ros_learning

That is all for today.

Whether you like the video or not, please leave a comment on the comments section below, so that we can interact and learn from each other.
