Sorry I am new to ROS.

May I ask, is there any navigation stack (for Turtlebot) that allows the robot to reach the goal location (in a known map) and go round some new, small obstacles on-the-way (not shown in the map). Do I need to add some user code in an existing stack?

Thank you very much.

Hi Chik,

Have you checked out the navigation stack? There you have all the information needed to get your robot navigating autonomously in no time.

This stack includes path planners that will allow your robot to navigate a known map while avoiding unknown obstacles.

For the case of turtlebot you can check out turtlebot_navigation stack

Have fun!

I watched the movie in navigation stack. This is cool! Does Turtlebot give the same navigation performance as PR2 ?

Well, PR2 is far more complex than Turtlebot and equipped with more sensors for navigation than just a Kinect. Which makes PR2 navigation "better" than turtlebot's, but the performance of turtlebot is good enough for hobbyists and even research
