2022-06-17 06:48:27 -0500 | marked best answer | tips to improve gmapping results Greetings, I am running slam_gmapping ( gmapping ) in PioneerAT with Sick LMS200 on ROS Diamondback. I am using slam_gmapping_pr2.launch from gmapping package. Following picture shows the result. TF defined is also visible in image. The map is curved on straight corridors. Parallel corridors are merged. A small circular move (loop ~ radius 3meters, at center) is not detected. One corridor has come twice (parallel,joined) due to some problem. I tried changing the launch file and used following: This resulted in even worse map shown in picture below: (more) |

2021-07-15 22:58:38 -0500 | marked best answer | Spatial_temporal_voxel_layer not being populated Greetings , I am trying to setup the tutorial of Spatial Temporal Voxel Layer (STVL) from the offical website on ROS Foxy (installed using debs), Ubuntu 20.04. STVL is compiled from source (foxy-devel branch). The params are as follows: I am using identical params for local-costmap. I am able to run simulation with 2D LiDAR but not with Realsense sensor. EDIT 1: The echo of topic 'intel_realsense_r200_depth/points' is as follows: Given that height is read as 1, is sensor data correctly being published? Am I missing something in settings? Thanks |

2021-05-23 05:57:53 -0500 | marked best answer | gmapping output very large 4000X4000? hi, We just ran Pioneer with ROS navigation stack with slam_gmapping node. The output of the map is 4000x4000 (appx. 15 MB) irrespective of size of environment explored. If I try to use this map for sbpl_lattice_planner, it just waits for the map. I can visualize map in rviz. The map is grey (may be to refer to unknown area). But rviz & system hangs. Is this behaviour because of big size of map?? I can not find which parameters to use to set map bounds? Any ideas? Update 1: I tested it one other laptop. I may be because of hardware problem , not able to handle Rviz! is it possible with i5 processor? prince |

The following errors are reported: I have tried downloading and compiling ros2 branch of bond_core. But it also results in compilation error: It appear that I am combining incompatible versions of the navigation2 stack with bond_core. Please share the correct configuration of nav2 library and dependencies. Thanks a lot. |
