2015-05-19 22:05:33 -0500	answered a question	base_local_planner does not follow the global plan accurately Hi,Naman, martin have pointed some good tips. But, map's resolution is a unnoticed point, I solved the similar problem by changing the costmap's resolution. The costmap's resolution must be equal or greater than the gmapping's map resolution. Hope it helps you out. GOOD LUCK!

2014-12-25 20:20:06 -0500	commented question	Add or remove obstacles in global_map @David Lu Anytime I want to. Most of the time is during the robot running. in other words, the obstacles is moving in the global map when the robot navigateing.

2014-12-24 20:26:35 -0500	asked a question	Add or remove obstacles in global_map Hi everyone, I have a TurtleBot,it's working fine with gmapping and navigation. Now,I want to add an obstacle in the global_map anywhere I want to so that the global_planner can avoid it when the robot navigtes. Some times,I also need to remove the obstacle from the global map. Can I achieve this goal by creating a new costmap layer? I am a novice and using Hydro with ubuntu 12.04. Could you give me some tips? thank you in advance! ps: Merry Christmas :)

Can I solve this problem by creating a new layer? like this tutorials teach us.http://wiki.ros.org/costmap_2d/Tutorials/Creating%20a%20New%20Layer. I am a novice and using Hydro, many thanks!
