robot notes for anna by anna

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

• left / regular mouse button: rotate the view
• middle button (how?): move the view or focal point
• host click / right click / scroll: zoom

create a map from log data and watch it on rviz

$ roscore
$ rosparam set use_sim_time true
$ rosrun gmapping slam_gmapping scan:=base_scan
$ rosrun rviz rviz
$ rosbag play ~/ros/gmap_tester.bag
$ rosrun map_server map_saver

topics

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