# Summary The previous URDF directory structure used has a chained call from **openarm.urdf.xacro** -> **openarm.xacro** -> **openarm.ros2_control.xacro**. **openarm.xacro** takes both robot hardware description and control/communication configuration arguments but the file content is only about robot description. # Changes Made - Renamed **openarm.xacro** to **openarm.robot.xacro**. This file now contains only the robot's hardware description, including links, joints, visuals, and inertial properties. - **openarm.control.xacro** handles all ROS 2 control configurations, including hardware interfaces, joint interfaces, and CAN device setup. - Updated openarm.urdf.xacro (entry point)Calls both **openarm.robot.xacro** and **openarm.control.xacro**. This change should separates responsibilities and arguments for each subsystem. Have tested with bringup scripts for both single-arm and bimanual configurations.
