Problem with Robotino when starting robotino_navigation.launch

edit

Hey there,

I want to navigate through a room with SLAM using gmapping. I already mapped this room in the following way ( http://wiki.ros.org/robotino_navigati... ):

roscore
roslaunch robotino_node robotino_node.launch
roslaunch robotino_teleop keyboard_teleop.launch
roslaunch robotino_navigation gmapping.launch
rosrun map_server map_saver -f /tmp/mymap

So I created a nice map of the room, in which I want to navigate through.

As soon as I start

roscore
roslaunch robotino_node robotino_node.launch
roslaunch robotino_teleop keyboard_teleop.launch
roslaunch robotino_navigation navigation.launch map_file:=/tmp/mymap.yaml

as described in http://wiki.ros.org/robotino_navigati... I get the following Error message in the robotino_node window multiple times:

"No Transform available Error: "map" passed to lookupTransform argument target_frame does not exist."

The rviz interface fires up with my map and I can drive through using keyboard_teleop and he moves in RVIZ.

When I send him a goal with "2D-Nav-Goal" he does not move.

Can anybody help me?
