Hey guys,

I try to develop an autonomous driving car. The problem is that I don't know how to localize the car on my SLAM map.

I only use a LiDAR UTM-30LX LiDAR to navigate. I created successfully a SLAM map with hector mapping.

Now I want to estimate a start point and a goal. I use the navigation stack with move base to navigate. As local planner I have implemented the teb_local_planner because of the Ackermann steering. I can estimate a start point and can set a goal. I also can forward my cmd_vel to the car with a steering angle and a speed info. But the position of the robot on the map in rviz don't change.

Can you help me and tell me what I have to do? I can't start playing around to find a good config for the teb_local_planner like this :(

Here is my launch file:

My amcl_pose dont update, but the car is moving with the speed and angle from the first input :/
