| 2014-08-25 05:54:14 -0500 | asked a question | problem with move_base I am trying to control a bot with a lidar. When i run the launch files to switch on the lidar and obtain the cmd_vel values from rosserial based on odometry data, the cmd_vel is being published by the move_base.launch file. But, when i run the navigation stack which uses this data, I get an error that says-" THe bot cannot move forward". A little debugging tells me that the navigation stack subscribes to cmd_vel from move_base. But, the cmd_vel is not being output by the launch files itself. How to solve this problem?q |

| 2014-08-23 03:48:08 -0500 | commented answer | Roslaunch not able to detect launch file packages Yes I kinda figured that.. but manually writing and replacing the manifest.xml with a package.xml does not seem to help! Can u suggest any other method? |
| 2014-08-23 02:10:46 -0500 | commented answer | Roslaunch not able to detect launch file packages The folder actually contains a CMakeLists.txt and a manifest.xml. I understand that manifest.xml is generally for rosbuild variants... but I am working with catkin. Also, I forgot to mention that I am working with ROS Hydro. |

| 2014-05-15 07:50:54 -0500 | asked a question | Slam_gmapping prob with lidar and image data I am trying to integrate Laserscan data and image data converted to Laserscan data into a single map using slam_gmapping. But, when i run the move_base launch file, the map takes only one of the laserscan data inputs( either image data or lidar data... not both!) Can someone help by explaining how to solve the problem? I believe the problem might be in the launch file. |
