2016-06-28 22:17:21 -0500 | marked best answer | Conversion between world and occupancy grid msg Hi all, I have a map of the environment my robot has to move in. The map is stored in the standard way as an occupancy grid map and served via map_server service. I want to implement a PRM on top of this map so I need to access the value of the occupancy grid from the world coordinate. To be more precise, given a point in the map frame (say [x0,y0]), I need to access the value of the occupancy grid of [x0,y0], that is, I need a conversion from the world coordinate to the index of the vector that represents the occupancy grid. Do I have to implement everything from scratch or there are already some api that perform this conversion? Regards |

2016-01-21 05:55:08 -0500 | asked a question | sbpl_lattice_planner map resolution Hi all, I'm using the sbpl_lattice_planner package and I noticed that whereas it works fine when the map resolution is 0.025 (2.5cm), it always fail to find a solution when the resolution is 0.05 (5cm). So far, I just modified the resolution parameters in the motion primitive generator to have them consistent with the map. It seems that the performance of the planner are affected by the resolution of the map, which shouldn't be the case if the motion primitives are changed accordingly. Should I modify some other paramters? Best |
2016-01-12 08:26:23 -0500 | asked a question | nested metapackages Hi All, I know that packages can be nested using metapackages so that a metapackage can contain multiple packages. Is it possible to nest metapackages (metapackages within a metapackage). Best |

2015-01-27 06:23:54 -0500 | asked a question | move_base - missed desired rate Hi all, I have a quite high level question. I'm currently trying to unplug the amcl node from the navigation stack and substitute it with a custom localization algorithm. Although I'm able to broadcast the transformation /map -> /odom with a high frequency (40Hz), I'm getting lots of errors such as as well as I was wondering what can cause such an error. The parameters in move_base are set so that the /amcl is not popping any of those warnings/errors. Thanks and regards. |
2014-11-25 03:03:25 -0500 | commented answer | costmap_2d::VoxelLayer not clearing Thanks for your suggestion. I'll try it but I think that the VoxelLayer now treats each observation independently so that clearing and marking are applied to each observation source without affecting the others. Anyway, I can be wrong. |

2014-11-05 10:26:27 -0500 | commented answer | Problem with subscriber within costmap layer Probably you're looking the wrong branch. pedestrian-layer should be the right branch to check. |

2014-11-04 07:37:17 -0500 | commented answer | Problem with subscriber within costmap layer As far as I remember, the solution I found was to run the node with the publisher first. Once the topic is published, run the move_base node (eventually with your plugin). Take a look at my github account (federico-b), the pedestrian_layer repository, there should still be the whole source code. |
