2013-04-01 13:05:08 -0500	commented question	A Multi Map Navigation Question: "set_map" service Do you get "Waiting for position" in your logs (check with grep)? If so, then AMCL or another localization system needs to be running - the robot is not getting its position.

2013-04-01 13:04:13 -0500	commented question	A Multi Map Navigation Question: "set_map" service Do you get "You must specify a definition_file" in any of your logs (check ~/.ros/logs/ with grep)? If so, then you have not properly specified a file for definitions of the map - the yaml file that links them all together.
2013-04-01 13:02:46 -0500	commented question	A Multi Map Navigation Question: "set_map" service What is your transition_types parameter set to? If there is no transition_types then it will default to requesting a bunch of transition actions to be present. Add <param name="transition_types" value="" /> to your node launch if it is not there.
2013-04-01 13:00:58 -0500	commented question	A Multi Map Navigation Question: "set_map" service Are all map_store services there? The system won't advertise set_map until map_store/list_maps, map_store/publish_map, and map_store/dynamic_map are connected up.
2013-04-01 12:59:24 -0500	commented question	A Multi Map Navigation Question: "set_map" service Is the launch file that starts the multi_map_navigation node actually getting run? See if it is in the results of 'rosnode list'. If not, then roslaunch is for some reason not getting to that file.
2013-04-01 12:58:54 -0500	commented question	A Multi Map Navigation Question: "set_map" service Sorry for the late response. This most likely means that multi-map navigation can't start up for some reason. Here are a set of steps to troubleshoot, based on the source code.
2012-08-21 08:38:49 -0500	answered a question	Building Android App Chooser with ROSJava Build from source on Fuerte is to my knowledge untested, however the electric built apps are known to work with Fuerte systems. android_app_chooser uses the ROSJava implementation and uses a ROS script to set itself up automatically. If you want to build it or create your own android app, you should follow the tutorials at: http://www.ros.org/wiki/ApplicationsPlatform/Clients/Android. However, you should not need to do this if you want to use the applications without modification as you can simply download them from the android market.
2012-08-21 08:33:02 -0500	commented question	Building android_core Can you actually open the SDK manager? If not this sort of behavior is often caused by the lack of 32-bit compatibility libraries on a 64-bit system.
2012-08-21 08:28:39 -0500	commented question	ROSJAVA Client Service md5sum not matching How are you building the android client? Are you building both from the same package tree so you are sure there is no difference?
2012-07-13 13:33:23 -0500	commented question	android App Chosser RuntimeExeption Error This sounds like a networking problem. Often times NAT or a firewall makes the connection one way between the robot and the android device. You can test this by pinging the device from the computer. Check the settings of the device to find the IP.

2011-09-02 12:28:03 -0500	commented answer	Hang on wait_for_server() on import, but not direct use I think you are missing a rospy.init_node(...)
