Catkin Workspace

Before you start downloading the different ROS packages, you need to create a catkin_ws to hold them in. If you already have a workspace in your /home/workspace directory, it is recommended that you keep a copy of it by renaming it to catkin_ws_saved. By doing so, you’ll avoid any possible conflict with pre-installed packages.

Udacity Workspace

For this lab, you'll get a chance to work in the Udacity Workspace. Thus, move to the next concept, enable GPU, and GO TO DESKTOP.

Now, follow these steps to create your catkin_ws and perform a system update:

Create Catkin Workspace:

$ mkdir -p /home/workspace/catkin_ws/src
$ cd /home/workspace/catkin_ws/src
$ catkin_init_workspace
$ cd ..
$ catkin_make

Perform System Update/Upgrade:

$ apt-get update
$ apt-get upgrade -y
