Hi, everyone,

I'm working with Electric Turtlebot on ubuntu 11.10.

After downloading the latest mercurial source code of turtlebot_apps, the android "make a map" app works fine on my Android tablet.

But when i try to save the map, there's an error message on the turtlebot netbook:

[ERROR] : Dynamic map getter service call failed.

It looks fine on the Android tablet though: "Map has been named xxxx."

Then I try to start the map navigation app, the tablet shows video stream, but can't load any map: "Starting the map selection service.."

After a few seconds, it just crushes.

Also the map manager app can't be started as well.

I've been looking at the topic data, it seems there's data published on /map when i try to save a map, but then the error messages appears, the SaveMap function stopped, and no data is published over /save_map.

Does anyone how to fix this problem??

Or is there anyway to get the source code of the android app? I might be able to have a look at the code and fix my problem.

Thanks....

Update:

update the latest changes in turtlebot, and change the android_map_nav.launch file: from: <node pkg="map_store" type="map_loader" name="map_loader" output="screen"/> to: <node pkg="map_store" type="map_manager" name="map_manager" output="screen"/>

Now it works!
