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/image_mono (although there is data on the /camera/ir/image_raw 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.
