Odin Rqtclose 🌟

def _spin_ros(self): rospy.rostime.wallsleep(0) # Allow ROS callbacks

This error is not a standard ROS output. Instead, it typically surfaces when a custom rqt plugin or a node named "Odin" (a common internal codename for autonomy stacks, custom executors, or specific robotic platforms) fails to close its ROS GUI components gracefully. The rqtclose signal indicates that the GUI was either forcibly terminated, lost a connection to the ROS master, or encountered a deadlock during shutdown. odin rqtclose

import signal signal.signal(signal.SIGTERM, my_shutdown_handler) If that handler calls sys.exit() without cleaning up rqt , you’ll see rqtclose errors. Modify your rqt plugin’s shutdown_plugin() method: def _spin_ros(self): rospy

import rospy from python_qt_binding.QtCore import QTimer class OdinRqtPlugin: def (self, context): self._node = rospy.init_node('odin_rqt', anonymous=True) self._timer = QTimer() self._timer.timeout.connect(self._spin_ros) self._timer.start(10) # Process ROS events every 10ms import signal signal

rosnode list After rqtclose fails, run again. If the rqt node still appears, it’s still alive. Force-kill it:
