2016-06-03 06:52:09 -0500 | asked a question | cv_bridge with rosjava I am somewhat confused how I can use cv_bridge with a rosjava node. I see that there is code around to convert a ros image (sensor_msgs.Image) to an OpenCV image,
but I get errors for this and the import, I have tried to add this dependency in package.xml
But it doesn't help. Is there something I need in the build.gradle file? This is on Ubuntu 14.04, Netbeans *.1 with gradle. |
2016-04-01 14:05:27 -0500 | asked a question | How to handle node shutdown in java code? I am trying to work out how to gracefully shutdown my node, without ctrl C. I assume that "rosnode kill" should close down the node, but it doesn't. I have the code below in my node but it is never called. Though when I run "rosnode kill" I do see in the log this "Shutdown requested by /rosnode with message "user request"". So how should shutdown be handled in the code?
