I am working on a project of Autonomous navigation using Laser, Hokuyo and Odometry but i do not understand how to begin and i never worked on ROS before so it would be grateful if someone can explain me the steps to start. Thank you. awaiting.

Thank you.

What have you tried? Have you looked at the navigation documentation?

Asking for someone to explain to you an entire field of work is unrealistic. Please indicate what you’ve tried yourself and maybe we can nudge you in the right direction.

Thank you Steven for your reply. I have started to study the tutorial of AMCL, odometry, laser scan working, laser scan message and navigation stack. And i just setup my rviz for the laser and i having difficulty to setup gmapping. So this is what i have done till now. But i do not have the exact clarity what shall be the first step to begin.

Thank you for your reply.

I would suggest to go through some tutorials with a functioning navigation stack. I personally liked the Turtlebot 3 tutorials and the Clearpath instructions and demos. Both describe how to simulate the robot, so you don't need the hardware to learn from them. If you are more into reading, I would suggest the ROS Robot Programming book. Chapter 10 addresses mobile robots and chapter 11 SLAM and Navigation.

Thank you so much for your detailed explaination. Its a nice tutorial to understand. Now i am trying to do the practical on turtlebot3 but when i try to run the code roslaunch turtlebot3_bringup turtlebot_3robot.launch it gives me an error that turlebot3_robot.launch is neither a launch file in package turtlebot3_bringup a launch file name. The traceback for the exception was written to the log file. Please give me the solution how to progress. Thank you for your reply.
