I'm a newbie for ROS. Currently i'm trying to use Hokuyo URG sensor to make a map by a mobile robot. I checked the odometry of the robot and for me, it seems correct. Plus i was using Encorder + IMU through EKF. Somehow at the end i got a map which is not aligned with laser data like in following picture. Can you guys suggest me the reason why this is happening? thanks alot!
