Can't navigate and use camera at the same time

I am working on a project that requires both navigation and object recognition modules. The problem I have is that modules work when they are run individually but as soon as I try to run them simultaneously then one fails. I I start amcl first I can do the navigation but there is no data from the /camera/rgb/imagemono (although there is data on the /camera/ir/imageraw topic) topic even after running roslaunch openni_launch openni.launch.

If I start openni.launch first then in amcl I get the error :

extrapolation error looking up robot pose.

Can I not do both at the same time when using the /camera/rgb/image_mono topic?

I am using the Kinect Sensor that comes with the turtlebot for both recognition and navigation. The ros distribution is groovy.

Please be more specific about your robot and your setup. Which sensor are you using? Are you using the same sensor for navigation and object recognition?

I have the same issue. I am also working on a turtlebot with the Groovy ROS distrubution, and I am trying to get navigation and object detection to run at the same time. Does anyone have any ideas on how this can be accomplished?

My best guess without further info is that both move_base and your image processing node are very computer intensive, so you may be short on resources.
