Hello, I am a beginner in ROS. My system contains a rplidar sensor directly connected to my PC and Noetic. I have already built a map using hector slam. Now I want to locate my sensor in the given map. After searching through the web I found everyone using AMCL to locate but I don't know what I need for that or how to implement AMCL. I would be very happy if someone has any information or websites that could help me, as I am a beginner. Thank you in advance
