Odin Rqtclose -

#!/bin/bash # odin – correct wrapper for rqt rqt_pid="" function cleanup if [[ -n "$rqt_pid" ]]; then kill -TERM "$rqt_pid" wait "$rqt_pid" echo "odin rqtclose: clean exit" fi

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 Outdated python-qt-binding or ros-kinetic-rqt-gui (or Melodic/Noetic) can cause shutdown deadlocks.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

def _spin_ros(self): rospy.rostime.wallsleep(0) # Allow ROS callbacks If it closes cleanly, the problem is in your Odin wrapper

rosrun rqt_gui rqt_gui Then close it. If it closes cleanly, the problem is in your Odin wrapper. If rqt itself crashes, you have a system-level ROS issue. If you use a launch file (e.g., odin_gui.launch ), look for: If it closes cleanly
