problems with map hectorslam
Hi guys, I've build a small rover with a Lidar A1m8 on it. It has 4 dc motors that I control from the keyboard. I followed the tutorial so I run the rplidar and the hectorslam nodes in order to get a map. The problem is that when I move the robot the map overlaps. Any suggestions/ ideas of the causes and how I can solve it? Thanks!!
