2018-02-08 15:27:50 -0500 | marked best answer | Unable to start costmaps in navigation stack Hello everyone. I am now working with the Create 2 robot - Roomba 600 platform - with the driver from AutonomyLab and a Hokuyo LRF. Everything is running perfect, but when I try to enable the navigation stack, the terminal does not log activation of obstacle layer and inflation layer, meaning the costmaps are not enabled on Rviz. Meanwhile in Gazebo everithing works smoothly with the same parameters settings, so I have two computers connected in the same wireless, this is the procedure I take*
Communications is realized with a local VPN, port 1194 over UDP. I tried many possible solutions but no one seems to work in a stable way, so I would like to ask for your help here.
One thing that made me think is about the view_frames output that is very different from gazebo case, which uses Il'post here some important screenshot and config settings and outputs: In common_costmap_params.yaml: From navigation stack logging: From view frames: It's showing 20 Hz on slam_gmapping, robot driver and LRF sensor with also: The tf parts published by And in these components of the frames at "most recent transform" I have: The important effect of all of this is that move_base_node ends up to not be a subscriber of /base_scan, so the obstacle plugins cannot enable. I think wrote the most important effects for me, but if you suggest to post something else i will be happy to. I would be very grateful to the ones who want to give suggestions or ideas. |
