DelftX: ROS1x Hello (Real) World with ROS – Robot Operating System

The weekly content only needs to be downloaded once you reach the respective week - don't download these in advance!

Each week content may include new versions of files/packages from previous weeks, always overwrite with the new version.

Any changes or additional files you've created, should be backed up before downloading the new week files.

When you download the contents for a week, some files that you might see in the instruction videos are already provided.  It is not necessary to create files that are already given to you.

Week 1 contents

All the files you need to work with for Week1 of the course are available in the zip file week1-contents.zip (~24 kB) .

Extract the contents of the zip file into $HOME/hrwros_ws/src/

After the above step, your folder structure under $HOME/hrwros_ws/src should look like this:

  • hrwros
      • hrwros_week1
      • hrwros_msgs

Run the following commands in the CCS terminal: 

  source /opt/ros/melodic/setup.bash
  cd $HOME/hrwros_ws
  catkin build
  source $HOME/hrwros_ws/devel/setup.bash

Week 2 contents

All the files you need to work with for Week 2 of the course are available in this zip file: week2-contents.zip (~3.2 MB) .

As explained in Week 1, the exact location of ROS packages is unimportant, as long as they are in the src space of your workspace. In this week we're going to make use of that, by placing the new packages directly in the src space, instead of in a sub directory.

Extract the contents of the zip file into $HOME/hrwros_ws/src.

Always overwrite all the previous content!

After the above step, your folder structure under $HOME/hrwros_ws/src should look like this:

  • hrwros
      • hrwros_week1
      • hrwros_msgs
  • hrwros_support
  • hrwros_week2

Now run the following commands in the CCS terminal:

  source /opt/ros/melodic/setup.bash
  cd $HOME/hrwros_ws
  catkin clean -y
  catkin build
  source $HOME/hrwros_ws/devel/setup.bash

At this point you are all setup to continue with Week 2 of the course and you can use the CCS as normal.

Week 3 contents

All the files you need to work with for the Week 3 graded assignments are available in the zip file: week3_contents.zip (~2.8 MB).

Warning: The downloads for Week3 will overwrite the contents of the hrwros_support package that you had received in Week2.

If you want to retain some of those changes, make sure to back them up properly. We are not responsible if you lose any local development you had inside the hrwros_support package.

Extract the contents of the zip file to your $HOME/hrwros_ws/src/. If it warns you folders and files will be overwritten, select Replace All.

After the above step, your folder structure under $HOME/hrwros_ws/src should look like this:

  • hrwros
      • hrwros_week1
      • hrwros_msgs
  • hrwros_support
  • hrwros_gazebo
  • hrwros_week2
  • hrwros_week3

Now run the following commands in a new CCS:

  source /opt/ros/melodic/setup.bash
  cd $HOME/hrwros_ws
  catkin clean -y
  catkin b
  source $HOME/hrwros_ws/devel/setup.bash

Now, your setup for Week 3 should be complete.

Week 4 contents

All the files you need for Week 4 are available in the zip file: week4_contents.zip (~152 kB).

Important Note: The downloads for Week4 include an updated version of the hrwros_gazebo package that you had received in Week3. Please overwrite it with the new version.
