Couldn't visualize laser scan and map at the same time
Hello, I'm beginner in ros environment. I have an rplidar A20 and I want to create a small aplication to localize the position of the rplidar and generate the path planning. So, I follow all steps in "ROS NAVIGATION IN 5 DAYS". I generated a map and I saved It with map_server map_saver. Then I loaded it by map_server map_server. But I found a problem at the beginning of the third video (https://www.youtube.com/watch?v=NANc8...) , exactly in the localization step by amcl. When I want to visualize the laser scan and the map in the rviz, always I have an error: For frame [laser]: Fixed Frame [map] does not exist. I understand that I can't have both the two at the same time. Also when I add the poseArray, I haven't clouds around the robot. Could you please help me to resolve this problem. Best regards
Hi, 1) Can you write your steps? (e.g. "roslaunch amcl amcl_diff.launch" , "rosrun map_server map_server <name-of-your-map>.yaml". etc.) 2) Can you upload a picture of the tf tree?
