I tested this in Ubuntu 24.04 with ROS Jazzy. After manually resolving the current merge conflict, all three packages built, all 27 tests passed, check_urdf passed, and RViz loaded the model without missing-mesh errors.
I am requesting changes before merge:
Merge or rebase current main and resolve display.launch.py. Keep the current model-loading logic from main and change its default model to full_arm_mar24.urdf.
Fix the joint model or correct the documentation. Right now only joint3 moves, while joint1, joint2, and joint4 are fixed. The documentation currently describes four revolute joints.
Remove the unused STL exports. The PR adds 95 STL files, but the URDF only references base_link.STL, shoulder.STL, elbow.STL, forearm.STL, and wrist.STL. The other 90 files add about 37.74 MiB and should not be included in the clean repository.
Rewrite or remove the outdated model documentation. It currently references assembled.launch.py, test_all.launch.py, waybionic_assembled.urdf, test_all_meshes.urdf, and backup files that are not included.
Confirm whether March 24 or May 26 is the accepted CAD revision. The imported model and the mechanical-team request currently disagree.
Add a massless root or world link and verify the base inertia. KDL currently warns that it ignores inertia on the root base_link.
The visualization itself works. Once the branch is cleaned up and the model and documentation agree, it should be ready to merge.

All 4 packages build and colcon test-result --verbose reports 53 passing tests. A collision probe still drove the mock arm into a blocked ready pose; move_group also exited with -11 during test shutdown without failing the suite. Details below.

Replay bypasses collision checking and sends positions straight to the controller, including the initial ready move. I added an obstacle at the ready pose: /check_state_validity rejected it, but Replay still moved the mock arm there. Route every replay segment through collision-checked planning and add a blocked-path regression. Checking only the IK endpoint is not enough.
There was a problem hiding this comment.
The ready move and XYZ segments now go through _plan_and_execute(), and the normal replay passed in my run. The tests still cover only an unobstructed replay and missing-service timeout, though. Please add the blocked-path case from this thread and assert that no trajectory execution is requested when the ready pose or a replay segment is obstructed.

Please add a post-shutdown assertExitCodes check. In this run, move_group segfaulted with exit code -11 during shutdown, but the launch test and all 53 workspace tests stayed green. Investigate that shutdown failure; the current test cannot detect it.

Reproduced on 2870bfa. Normal replay completes, but move_group then segfaults during shutdown in rclcpp::CallbackGroup::~CallbackGroup() and exits with -11. The new assertExitCodes now correctly fails the launch test. Please fix or isolate the shutdown cause and rerun both launch tests; allowing -11 would only hide the original problem.

This table still describes joint3 as continuous and the other limits as +/-3.14. The current URDF makes all four joints revolute with +/-1.5708 limits. Update the table and slider instructions to match, keeping the limits explicitly unverified.

Re-reviewed 2870bfa in an isolated Jazzy container. The normal replay completes through the new planning/execution path, and the missing-service timeout test passes. The replay launch test still fails because move_group exits with -11 during shutdown; the new assertion now catches that failure. The blocked-path regression and the earlier model-table correction also remain outstanding.
