Hands-On ROS for Robotics Programming

Cloning a ROS package

For the cloning option, we are going to use a basic GoPiGo3 ROS package that is publicly available in GitHub from https://github.com/ros-gopigo/gopigo3_node. Change to the src folder, which is the location where we will place all ROS packages, and then clone the source code:

$ cd ~/catkin_ws/src$ git clone https://github.com/ros-gopigo/gopigo3_node

Every time you add a new package, you have to rebuild the workspace so that ROS is aware of its existence and can add it to the execution environment. Hence, run the following commands:

$ cd ~/catkin_ws$ catkin_make

Now, you will see a number of lines indicating the progress in % and what the current building step is doing. If everything is okay, the last line displays 100% ...
