could not find camera topic on rviz
i was launching the techman robot on ros using the demo.launch. The first time when i launched it on rviz i could able to see the camera under by topic and I can see the video output. So i edited the moveit setup and added some pose to the robot. so when i launched again. now i could not find a camera under by topic.And i am very new to ros.
.
Can you please! tell me what camera are you using? Are you checking from your terminal whether you are able to subscribe to the camera channel.
You can do so by:
Just fire this command and check your topic is published or not.
no i tried it its not publishing
Then the problem is with your camera or camera package.
