Troubleshoot mapping/recording areas
Troubleshoot OpenMower mapping and area-recording issues. Covers map backup, deletion, and re-recording mowing areas via SSH.
We assume that you at least followed Record a map .
Making a backup and/or removing a map.
The default location of the map can be found under
/home/openmower/ros_home/map.json
You can always back up your current map by logging in via SSH and copying the .json file.
If you want to retrieve the file, you can use an SFTP client like WinSCP or Cyberduck.
sudo cp /home/openmower/ros_home/map.json /home/openmower/ros_home/map.json.backup
To delete the map
# stop the openmower service so that it doesnt access the map anymore
openmower stop
# check, if the map file is indeed there.
ls /home/openmower/ros_home
# delete maps (both .bag and .json)
rm /home/openmower/ros_home/map.bag
rm /home/openmower/ros_home/map.json
# restart OM
openmower stop
