navigation - Can't navigate and use camera at the same time in ROS -

i working on project requires both navigation , object recognition modules. problem have modules work when run individually seek run them simultaneously 1 fails. i start amcl first can navigation there no info /camera/rgb/image_mono (although there info on /camera/ir/image_raw topic) topic after running roslaunch openni_launch openni.launch.

if start openni_.launch first in amcl error :

extrapolation error looking robot pose.

can not both @ same time when using /camera/rgb/image_mono topic?

edit: using kinect sensor comes turtlebot. using same sensor both nav , recognition. not publishing anything.

navigation kinect openni robot ros
