Ros Programming how to open my saved map
Hi guys. I have a problem. I am beginner at ROS Programming. I use RVIZ for mapping. 1) I mapped with Turtlebot using this tutorial: link text . Then next day I tried to open my map using this tutorial: link text but my map didn't open. I can't understand how I will solve this problem.
2) I see that Turtlebot can't localize itself truly on the map when after I open the map at the same day.
do you see map in rviz ? or map is not loaded ?
For the first question, map file does not appear in directory which i saved map, this situation happens when i shut down the computer. For the second question map is loaded but robot can not find its location on the appearing map.
for 2. are you able to see localisation running ?
