The TUoS ROS Course Repo

A ROS Metapackage called tuos_ros has been put together to support these courses. This package is available on GitHub here. This repo contains the following ROS packages:

Package Name	Description
`tuos_examples`	Some example scripts to support certain exercises in The ROS 2 Course
`tuos_interfaces`	Some custom ROS interfaces to support certain exercises in The ROS 2 Course
`tuos_simulations`	Some Gazebo Ignition simulations to support certain exercises in The ROS 2 Course
`tuos_task_sims`	Simulation resources to support your development work in real robot based course assignments
`tuos_tb3_tools`	Scripts and visualisation tools for the Waffles (real and sim)

Installing¶

Early on in Part 1 of the ROS 2 Course we explain how to install the tuos_ros course repo, but here are those instructions again:

Navigate to your ROS Workspace src directory:
```
cd ~/ros2_ws/src/
```

Clone the repo from GitHub:

git clone https://github.com/tom-howard/tuos_ros.git -b jazzy

Navigate back one directory, into the root* of the ROS workspace:
```
cd ~/ros2_ws/
```
Run colcon build to compile the packages:
```
colcon build --packages-up-to tuos_ros
```
Then re-source your .bashrc:
```
source ~/.bashrc
```

Verify¶

Once you've installed it, then you can verify that the build process has worked using the following command:

colcon_cd tuos_ros

Which should take you to a directory within the repo that's also called tuos_ros, i.e.:

~/ros2_ws/src/tuos_ros/tuos_ros

Updating¶

The course repo may be updated every now and again, so its worth checking regularly that you have the most up-to-date version. You can do this by pulling down the latest updates from GitHub using git pull:

cd ~/ros2_ws/src/tuos_ros/ && git pull

If you see the following message:

-bash: cd: tuos_ros/: No such file or directory

... then go back and make sure you've installed the repo first!

Then, run colcon build and re-source your environment:

cd ~/ros2_ws && colcon build --packages-up-to tuos_ros && source ~/.bashrc
