nav2d Navigator failing to create path
Hello, I am trying to use nav2d with the turtlebot robot, in order to map an unknown room. I was able to modify the tutorial3.launch file and the costmap is created without problems. But when i try to add a goal in Rviz, the robot don't move and it show
[ERROR]: Prepare failed!
I also tried to use
rosservice call /StartMapping 3
but it only print response: 0
and shut down.
Here is my rqt_graph : http://img11.hostingpics.net/pics/270...
EDIT : The mapper log show the following error
[[33m[ WARN] [1444902817.579649858]: Failed to compute odometry pose, skipping scan ("base_laser_link" passed to lookupTransform argument source_frame does not exist. )^[[0m
