Hi there

i am doing a course project and am stuck on fairly easy task.

My robot model has a laser scanner and I generate a bag file from gazebo.

I am asked to generate a Occupancy grid map as we do in SLAM. I am NOT allowed to use gmapping or hector mapping so I have to write my own code.

right now I have achieved that I initialized the map and visualized it in rviz. It is fairly simple as I just set height, width, resolution and placed all zeros in .data.

My next task should be use the sensor data being published and generate a map. and here I am stuck as I cannot find some appropriate tutorials. However i found a good implementation of the same task but its too verbose for me to decipher. it is (http)

Can you please explain where can I get some help? Or you can also help me in the answer.

If you ask, I can paste my code also.
