2022-09-25 22:32:35 -0500 | marked best answer | move_base generating path in unknown space Hi,
I am trying to use ROS navigation stack with RPlidar A2.
currently, I am running This is my costmap_common_parmas.yaml This is my global_costmap.yaml This is my local_costmap_params.yaml and I am using dwa_local_planner and A* for global_planner. EDIT After accepting the answer, I worked on properly setting the costmap yaml files and now it works properly. I have played with 'track_unkown_space' param and I decided to set them like these. These are the files I have written. common_costmap.yaml global_costmap.yaml (here, I set 'track_unkown_space' to true, since I wanted A* planner to only plan in known & free space) - make sure you load these in move_base.xml file with namespace global_costmap. local_costmap.yaml (here, I set 'track_unknown_space' to false, since DWA planner works fine with this param being false.) I got this idea from this link text (more) |

2021-04-16 00:19:00 -0500 | marked best answer | updating the map partially in a dynamic environment Hello, I have generated map.pgm with I believe there are three possible options for this problem, (If there are other good solutions please let me know, thank you!)
I was wondering if there is a way to do the third option. I can create a node that sends out move_base goals and my navigation stack works. Is there any way to update already made map (made by gmapping) ? Since the already-made map used by navigation stack will be published by map_server, if there is a way to update the map and then save the map by map_saver, i will be able to solve this problem. Thank you for your help! |
