I want to construct 2D occupancy grids for mapping of an unknown environment. Could you guide me how can I achieve it?

What I have researched is that robot can construct its map given sensor data using recursive Bayesian estimation algorithm. Is it correct?

Yes you do need some sort of sensor data such as LIDAR data.

If you are planning to perform 2D SLAM then you could start playing around with the ROS package gmapping which will help you construct a 2D occupancy grid using LIDAR data.

Here is a simple tutorial that shows you how to use gmapping for this use case. Here is another tutorial that shows you how to do this in simulation.

This youtube video is also a good guide.

  • $\begingroup$ Hi Saad, I have never used V-REP but from the looks of it it has some level of ROS support as well. Have a look at this forum post . Someone seems to have figured out how to perform gmapping on V-REP! Hope this helps! $\endgroup$ – JJerome Jul 3 at 0:16
