2011-12-08 06:55:39 -0600 marked best answer Turtlebot amcl demo, using map-files from selected directory?

as @tfoote pointed out, the command should look like:

roslaunch turtlebot_navigation amcl_demo.launch map_file:=/home/turtlebot/freja02.yaml

Also, make sure your .yaml file points out the right location of .pgm file. Suppose you have freja02.pgm also in the home directory, you might want to something like:

emacs freja02.yaml &

This will open a text editor, then correct perhaps the 1st line where describes the path of .pgm file as:

image: /home/turtlebot/freja02.pgm

then save file by Ctrl-s (pressing control key and s). Close the window, and run the .launch file again.

You can edit maps using a standard image editor, so you can simply mark areas you don't wish the robot to go with black. The image format is PGM

2011-10-22 04:59:59 -0600 asked a question Manually editing maps.

I have areas in my map that i woul like the turtlebot to avoid, áreas cold be marked as free or unknown, but for different reasons, such as carpets, cluttered areas etc i would like the turtlebot to avoid these areas in it's 'path-planning...

Is this possibe ?

OK, this should be published as 'comment', but i can't acess the commenting tool. Not enought 'Karma* Ok, still want to share you my similar experiences.

My turtlebot have the same problem with the 'set estimate pose' command in RVIZ. I get the pose and robot model nicely published and displayed in RVIZ, but i can't set the initial pose, or any navigation goal. My setup sometimes work, sometimes dont.

The system seems to work on a fresh 'just made map'. trying the day after is more unstable...

Everything else displays nice on RVIZ, if i manually pushes or rotates the turtlebot, RVIZ updates the movement and add all the red arrow just as if it was working. I just cant set the pose estimate or the 2D nav goal.

A difference from your tutorials is that i'm not adressing the by 'DNS name' such as turtlebot@marvin, instead i adresse as described in another tutorial by turtlebot@

I use a dedicated WLAN with only the turtlebot and a remote computer, same IP:s from day to day. I have checked the network settings as suggested in a similar question

Is it likely that this is still an network error ?

What about the 'ticket, is this in progress?

Any workaround ? is upgrading to 'electric' a way forward ?

Thank you

2011-09-30 03:45:48 -0600 answered a question Turtlebot amcl demo, using map-files from selected directory?

I move two files, the .yaml file and the corresponding .pgm file

I have tried the 'roslaunch turtlebot_navigation amcl_demo.launch map_file:=/home/turtlebot/freja02.yaml' path as well without success.

However, as long as the requested files are available in the /tmp/ directory, the command will run, regardless of whar path i point out in the roslaunch turtlebot_navigation amcl_demo.launch map_file:=/home/turtlebot/freja02.yaml command...

I still think this might be related to my limited skills in Linux...


2011-09-29 03:51:15 -0600 asked a question Turtlebot amcl demo, using map-files from selected directory?

map files created with the turtlebot 'SLAM map building' tutorial are stored in the /tmp/ directory. I have tried moving the generated files to my home directory and the run the 'amcl-navigation demo' pointing to the files in this directory but the map-server does'nt seem to accept this. How can i store and reuse different mapfiles?

roslaunch turtlebot_navigation amcl_demo.launch map_file:=/turtlebot/freja02.yaml
