Description

Fixes #3799.

The Planning Scene and Motion Planning RViz displays now resolve a relative Robot Description against the configured Move Group Namespace before creating the shared RobotModelLoader. This gives each namespaced display a distinct loader key and subscribes to the matching namespaced robot_description and robot_description_semantic topics. Explicit absolute Robot Description names remain unchanged.

The RDF synchronized-string fallback now also sanitizes its temporary ROS node name. Without this, a namespaced description containing a slash would produce an invalid temporary node name before the topic could be read.

Validation

  • clang-format 14.0.6 on all changed C++ files
  • git diff --check
  • static regression assertions for namespace resolution and sanitized topic-loader path
  • Full ROS 2 / RViz runtime validation was not available on this macOS workspace; the draft is ready for CI compilation and maintainer feedback.

Checklist

  • Required by CI: code formatted with clang-format 14
  • Tutorials/documentation extension is not needed for this bug fix
  • Migration note is not needed; existing non-namespaced and absolute-name behavior is preserved
  • No screenshot: this changes loading behavior, not the UI
  • Full integration test is not included because the existing RDF integration-test harness is currently disabled in CMake

Summary by CodeRabbit

  • Bug Fixes
    • Planning Scene RViz resolves relative robot-description names within the configured Move Group namespace when loading the robot model. Absolute names remain unchanged.
    • String parameter subscriptions now handle names containing non-alphanumeric characters by converting those characters to underscores in the temporary node name.

📝 Walkthrough

Walkthrough

The RViz planning scene display now resolves the robot description against the configured Move Group namespace before loading the robot model. The RDF loader also replaces invalid characters in the temporary node name used for its string subscription.

Changes

Robot-description loading

Layer / File(s) Summary
Resolve and load namespaced robot description
moveit_ros/visualization/planning_scene_rviz_plugin/include/moveit/planning_scene_rviz_plugin/planning_scene_display.hpp, moveit_ros/visualization/planning_scene_rviz_plugin/src/planning_scene_display.cpp
PlanningSceneDisplay adds getRobotDescription(). When the namespace and description are non-empty and the description is relative, the accessor appends the Move Group Namespace. The display passes the result to the shared robot model loader.
Sanitize RDF loader temporary node name
moveit_ros/planning/rdf_loader/src/synchronized_string_parameter.cpp
waitForMessage replaces characters other than alphanumeric characters and _ in its temporary node name with _.

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to 48292

Namespaced RViz displays can fail to load models from existing parameter-only configurations that still use unprefixed robot-description keys. Address or explicitly accept this compatibility risk before merging.

Review details

Systems and components

  • observed — moveit_ros (service) was modified; 3 changed files map to changed impact.

Before / after behavior

  • observed — Modified behavior in moveit_ros/planning/rdf_loader/src/synchronized_string_parameter.cpp: Added #include <cctype> to support the new character-classification logic in waitForMessage.
  • observed — Modified behavior in moveit_ros/planning/rdf_loader/src/synchronized_string_parameter.cpp: In waitForMessage, the temporary node name string is now a mutable auto so each character that is neither alphanumeric nor _ is replaced with _, sanitizing the name for valid ROS node construction; previously the name was a const auto used unchanged.
  • observed — Modified behavior in moveit_ros/visualization/planning_scene_rviz_plugin/src/planning_scene_display.cpp: Added getRobotDescription(), which returns the robot description property value, or appends the Move Group Namespace to it via rclcpp::names::append when the namespace is non-empty and the description is non-empty and does not already start with /.
  • observed — Modified behavior in moveit_ros/visualization/planning_scene_rviz_plugin/src/planning_scene_display.cpp: createPlanningSceneMonitor() now calls getRobotDescription() when obtaining the shared robot model loader instead of passing robot_description_property_->getStdString() directly, so the namespaced description is used.

Preserve local parameter lookup when selecting a namespaced topic.

If RViz has local robot_description and robot_description_semantic parameters but the namespaced topics are not published, this call now asks the RDF loader for names such as /ns/robot_description. The loader queries those names on the RViz node, not on move_group. It then waits for topics and fails to load a model that loaded before this change. Separate the local parameter names from the namespaced topic names, or provide an explicit remote-parameter fallback. (github.com)
