Operating a 4-DOF Robot Arm within a ROS Environment To visualize a 4-DOF robot arm utilizing the URDF format, one must first establish a connection between their robotic system and the ROS (Robot Operating System). This entails ensuring the necessary dependencies are installed. The primary tools for this process include Rviz, which serves as the primary visualization platform, and the urdf_parser plugin. Firstly, verify that the appropriate dependencies have been installed. For most Linux distributions, this is typically achieved by running the following commands: sudo apt-get update sudo apt-get install ros-<distro>-rviz ros-<distro>-urdf-parserplugin Replace '<distro>' with your ROS distribution version. Next, launch Rviz and configure it to load the URDF file for your robot arm. This is accomplished by opening a terminal within Rviz and entering the following command: rosparam set /robot_description <path-to-URDF-file> Replace '<path-to-URDF-file>' with the actual path to your URDF file. The 4-DOF robot arm model should now appear in Rviz. To further interact with the model, one may use ROS commands such as 'rosrun' and 'rostopic'.
