Robotics beginner (CSE undergraduate) here. I have been working on a octomap based navigation system that explores an unknown terrain for some time. I completed a prototype navigation system and are now having some issues with localization.

I used dead reckoning so far since i cannot use a prebuilt occupancy grid (system intended for a mapless or deformed environment) but now need more accuracy. I came across bundlefusion and elasticFusion that focus on 3D Dense SLAM. but they have specifically said that they are not compatible with ROS. Because of this, I started looking for already implemented ICP based mapping and localization and came across these two. mrpt_icp_slam_2d which only supports 2D and ethzasl_icp_mapping which doesn't support kinetic.

Are there any other ros packages that i can use out of the box?

This might be a bit late. But as @Dragonslayer mentioned, I digged deep and selected RtabMap for my work. Posting this a

@HASSAN ISMAIL can you post the terminal output including the commands you used. (may be a image)

It depends on your approach, environment and the resources you have. I'll try to give an rough idea on this. Buckle up.

So, i may be late in answering, but can you add to what you said? able to do SLAM without falling down the stairs

can you upload the launch file you are using (one you use to load the kinect)?

That database use is what worries me. I'll try to run it and see. my use case is creating a map for a map less environme

yeah. dead-reckoning means using just wheel encoders. i will look into rtabmap
