Closing #504

Contributions via pull requests are much appreciated. Before sending us a pull request, please ensure that:

1. Limited scope. Your PR should do one thing or one set of things. Avoid adding “random fixes” to PRs. Put those on separate PRs.
2. Give your PR a descriptive title. Add a short summary, if required.
3. Make sure the pipeline is green.
4. Don’t be afraid to request reviews from maintainers.
5. New code = new tests. If you are adding new functionality, always make sure to add some tests exercising the code and serving as live documentation of your original intention.

To send us a pull request, please:

• Fork the repository.
• Modify the source; please focus on the specific change you are contributing. If you also reformat all the code, it will be hard for us to focus on your change.
• Ensure local tests pass. (colcon test and pre-commit run (requires you to install pre-commit by pip3 install pre-commit)
• Commit to your fork using clear commit messages.
• Send a pull request, answering any default questions in the pull request interface.
• Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.

please have a look at the failing CI jobs

Pretty sure I just fixed the child_frame issue + the failing Cl jobs in the newest commit "fixing spaces".

[rehanshah17]

This may be something very small that I am overlooking, but all the tests are failing from the first version of my code, instead of the newest commit. Is there something else that I have to do than pushing changes to the feature branch?

This PR doesn't even build. Have you tested it locally before?

[christophfroehlich]

have you run the tests locally?
$ colcon test --packages-select admittance_controller

for some reason I am not able to run these changes locally, colcon checks the install folder on my machine but the install folder is empty. Any help? This is the command and output

@rehanshah17 did you try building the package?

[christophfroehlich]

have you installed ros2_control as binaries, or do you want to build it from source? if it is in your workspace, run colcon build --packages-up-to admittance_controller

[rehanshah17]

I had to download it from robostack, so I am pretty sure I downloaded it from source.

I never used robostack, sorry. But you can clone the missing package from https://github.com/pal-robotics/backward_ros

@rehanshah17 can you please fix the failing test?
