tbd

  • can rosparams be set in a config file somewhere and auto-loaded?
  • it seems the /map frame in rviz is different from the /map topic? because rviz can't find the /map frame even when the /map topic is being published.

rviz view controls

  • regular click: rotate the view
  • shift-click: move the view or focal point
  • host click / scroll: zoom

create a map from log data and watch it on rviz

$ roscore
$ rosparam set use_sim_time true
$ rosrun rviz rviz
# make sure map is checked and subscribed to topic /map
$ rosrun gmapping slam_gmapping scan:=base_scan
$ rosbag play ~/ros/gmap_tester.bag
$ rosrun map_server map_saver

topics

  • gmapping:
    • /base_scan
    • /clock
    • /map
    • /map_metadata
    • /slam_gmapping/entropy
    • /tf
