      • The costmap generation is limited to 3m, although the PML goes out to 5, hence the dots in the distance (related to walls in the lab offices), where the costmap has not yet generated. So, the PML works for costmap generation on slower platforms -- that costmap was generated when going about 0.2m/s.

@CyberShadow: that's due to CMake's defaults. -DCMAKE_INSTALL_LIBDIR="lib" needs to be added to override the defaults. Technically this is equivalent since lib64 points to lib, but then pacman complains as it cannot handle that.

clear costmap is a recovery behavior, not itself a layer, so it should not go into costmap_2d, its a recovery plugin. Move base also exposes a clear costmaps service that people also typically used to clear costmaps so you dont have to get to a recovery state before calling it. Jun 16, 2018 · If you use ROS move_base navigation stack with a depth point cloud (to reveal obstacles), you might run into the issue of the local costmap not getting cleared, resulting in lingering "fake" obstacles. This article talks about several possible solutions.

I tested the correct functionality of the SICK LMS-200 laser using both player and Aria demo 1. Creation of cfg file In order to test it with player I had to create a new .cfg file named sick.cfg which only content is the driver for the laser as follows: This example shows how you can distribute the Automated Parking Valet (Automated Driving Toolbox) application among various nodes in a ROS network. Depending on your system, this example is provided for ROS and ROS 2 networks using either MATLAB® or Simulink® . The costmap automatically subscribes to sensors topics over ROS and updates itself accordingly. Each sensor is used to either mark (insert obstacle information into the costmap), clear (remove obstacle information from the costmap), or both. A marking operation is just an index into an array to change the cost of a cell.

Re: Clearing old obstacles from costmap Yes, rotating the robot does not clear them out (unless I rotate to a configuration where another farther away obstacle appears behind the phantom obstacle). Translating the robot towards the obstacle does not clear them out either until the robot almost drives on top of them. .
