Introduction: When Your ROS GUI Vanishes If you are a robotics software engineer working with the Robot Operating System (ROS), you have likely mastered the rqt suite—a powerful framework for graphical user interfaces (GUIs) that includes tools like rqt_graph , rqt_plot , and rqt_console . However, an obscure but critical error has been appearing in forums and debug logs: "odin rqtclose" . odin rqtclose
def _spin_ros(self): rospy.rostime.wallsleep(0) # Allow ROS callbacks and rqt_console . However
rqt --force-discover --close-with-master The --close-with-master flag ensures rqt exits if the ROS master dies, preventing hangs. Outdated python-qt-binding or ros-kinetic-rqt-gui (or Melodic/Noetic) can cause shutdown deadlocks. Update: odin rqtclose
