Description of contribution in a few bullet points

Add CostmapSource to Collision Monitor to allow collision checks against a subscribed local costmap (nav2_msgs/Costmap).
Wire CostmapSource into CollisionMonitor::configureSources() and expose params:
- *.topic, *.cost_threshold (0–255), *.treat_unknown_as_obstacle (bool).
Provide minimal example in params/collision_monitor_params.yaml.
Update README.md:
- Add Costmap to the list of supported sources.
- Add a concise note about latency warning when using a costmap source.
Add dataset-based integration test (bag replay):
- test/collision_monitor_node_bag.cpp (metrics: time-to-stop, hold-stop%, time-to-resume, false-stop%).
- test/collision_monitor_node_bag.launch.py to bring up CM, play a tiny bag, and run gtest.
- Tiny mcap.zstd bag + test YAML installed for get_package_share_directory().

Description of documentation updates required from your changes

docs.nav2.org (separate PR): add a short .. warning:: box on the Collision Monitor page describing the trade-offs of using a costmap source (persistence vs. latency/staleness), and list the new parameters.
Ensure the new source and parameters are included in any parameter reference and tuning sections.
(This PR) README.md already updated with a brief note and source entry.

Description of how this change was tested

Unit/launch tests: Added a launch gtest that replays a tiny bag and checks CM behavior (time-to-stop, hold-stop%, time-to-resume, false-stop%). Ran colcon test --packages-select nav2_collision_monitor; existing unit tests + the new launch test pass on Ubuntu.
ABI: Verified that ABI was preserved.

Future work that may be required in bullet points

For Maintainers:

Check that any new parameters added are updated in docs.nav2.org
Check that any significant change is added to the migration guide
Check that any new features OR changes to existing behaviors are reflected in the tuning guide
Check that any new functions have Doxygen added
Check that any new features have test coverage
Check that any new plugins is added to the plugins page
If BT Node, Additionally: add to BT's XML index of nodes for groot, BT package's readme table, and BT library lists
Should this be backported to current distributions? If so, tag with backport-*.

@Lotusymt, your PR has failed to build. Please check CI outputs and resolve issues.
You may need to rebase or pull in main due to API changes (or your contribution genuinely fails).

Checkout Linting / CI jobs that are failing. You may need to pull in main / rebase as well.

Please provide some comments inline in the test files so someone can understand what each are doing -- its a little difficult to read them and understand (1) fully what each do, (2) the difference in what one covers the other doesn't, and (3) the intent

But, by in large, this looks great!

Hi Steve,

I’ve updated the PR to address the issues you pointed out:

Removed the coverage exclusion and the old comment.
Cleaned up the formatting you mentioned earlier.

Right now, the uncovered lines are mainly the branch that handles malformed /local_costmap/costmap data, which should not trigger in the normal “happy path”.

If you think we should explicitly cover this failure mode, I’m happy to add a small unit test that publishes invalid data and hits this branch. Please let me know your preference, and I can update the PR accordingly. Thank you!

SteveMacenski · 2025-11-18T17:40:55Z

If you think we should explicitly cover this failure mode, I’m happy to add a small unit test that publishes invalid data and hits this branch

That would be nice, yes. It should be easy by sending it a bogus costmap manually in the unit tests.

Also, do you think the costmap source should be added to the collision detector node as well?

Finally, just need to update the migration guide in ros-navigation/docs.nav2.org#804 and we should be ready to merge!

Lotusymt · 2025-11-18T23:53:59Z

Thanks, Steve!

I’ve added the unit test to cover that branch.

I agree it’s more consistent to support CostmapSource in the collision
detector node as well. I’ve added CostmapSource there and included a
corresponding unit tests for the collision detector.

Finally, I’ve updated the migration guide in ros-navigation/docs.nav2.org#804
to mention the new CostmapSource option for both CollisionMonitor and
CollisionDetector.

Please let me know if you’d like any of these changes structured differently.

I think this is unrelated to this PR and needs to be reverted

Thanks for catching that — I totally agree this change is unrelated to the PR.
I think it was accidentally modified earlier when I was experimenting with a small script to debug some linter issues.
I’ve now reverted the line back to the original license text, and the linter tests still pass.

Can we use ament_add_gtest instead?

Thanks for pointing this out!
I kept this as an add_executable on purpose: the binary is a gtest-based helper that’s launched from collision_monitor_node_bag.launch.py.
If we register it with ament_add_gtest, colcon test / CTest would try to run it standalone without that launch setup, so it would block waiting for /clock and /cmd_vel or fail with no data.

Ah, I think we can use ament_add_gtest_executable and ament_add_test instead,

, no?

Good point, thank you for pointing that out! Your suggestion would definitely be more consistent with the existing style. Since this PR is already merged, I’ll keep the current version for now, but I’ll keep this pattern in mind for future tests.
