Description

Steps to reproduce:

  1. When calling RobotModelLoader::configure at the statement below

    rdf_loader_ = std::make_shared<rdf_loader::RDFLoader>(opt.urdf_string_, opt.srdf_string);
    we initialise an rdf_loader with ros_name_set to "".
    As shown currently ros_name_ is not set in the second constructor for the rd_loader_
    : urdf_string_(urdf_string), srdf_string_(srdf_string)

  2. Then when attempting to create a kinematic plugin loader below at line 268

    std::make_shared<kinematics_plugin_loader::KinematicsPluginLoader>(node_, rdf_loader_->getRobotDescription());
    we are returned an empty string from getRobotDescription() as shown
    The getRobotDescription() method returns ros_name_ which is currently set to "":
    The KinematicsPluginLoader object then sets it's robot_description_ to an empty string as shown in it's constructor.

  3. At line 260 of kinematics_plugin_loader the kinematics_param_prefix is set with an empty string from robot_desription_ leading to a string starting with "_kinematics."

    std::string kinematics_param_prefix = robot_description_ + "_kinematics." + known_group.name_;
    The kinematics_solver_param_name is then set based on the kinematics_param_prefix variable as depicted
    std::string kinematics_solver_param_name = kinematics_param_prefix + ".kinematics_solver";

  4. This cases the error to be logged:

    RCLCPP_DEBUG(logger_, "No kinematics solver specified for group '%s'.", known_group.name_.c_str());
    [DEBUG 1753159891.197749171] [operation_solver.moveit.core.robot_state]: No kinematics solver instantiated for group 'manipulator' (setFromIK() at /home/ros/ros2/src/moveit2/moveit_core/robot_state/src/robot_state.cpp:1863)

Summary by CodeRabbit

  • New Features
    • String-based robot description loading now accepts an optional ROS name. Specify a name to use it for the loaded descriptions, or omit it to keep the default, robot_description.
    • Existing usage with URDF and SRDF strings remains supported without requiring changes.

📝 Walkthrough

The string-based RDFLoader constructor now accepts an optional ROS name. It defaults to "robot_description" and initializes ros_name_ from the supplied value.

Changes: RDFLoader constructor

Layer / File(s) Summary
Add ROS name parameter
moveit_ros/planning/rdf_loader/include/moveit/rdf_loader/rdf_loader.hpp, moveit_ros/planning/rdf_loader/src/rdf_loader.cpp
The constructor declaration adds ros_name, defaulting to "robot_description". The implementation stores the supplied value in ros_name_.

Models loaded from strings with a custom description name can miss their joint-limit and kinematics settings. Pass the configured name while retaining the default for empty names before merging.

Explanation

The title accurately describes the main change: adding a default ros_name value to the second RDFLoader constructor. It is specific enough to identify the affected API change, despite slightly awkward wording.

Pass the configured name while preserving the default.

When both model strings are present, configure() ignores opt.robot_description. A custom name therefore falls back to "robot_description" and produces incorrect joint-limit and kinematics prefixes.

The two-string Options constructor leaves robot_description empty, so preserve the default when passing the name:

🐛 Suggested fix
-    rdf_loader_ = std::make_shared<rdf_loader::RDFLoader>(opt.urdf_string_, opt.srdf_string);
+    const std::string robot_description =
+        opt.robot_description.empty() ? "robot_description" : opt.robot_description;
+    rdf_loader_ =
+        std::make_shared<rdf_loader::RDFLoader>(opt.urdf_string_, opt.srdf_string, robot_description);
