2019-05-20 02:08:22 -0500 | marked best answer | robot_localization not generating odom to robot's sensor_frame transform Hello all, I'm trying to fuse an IMU and a DVL (measures linear velocity on x, y, z). I have the following axis configurations.
I have a transform broadcaster which broadcasts base_imu->base_link and base_dvl->base_link. The picture attached shows the frame poses. I have set the fixed frame as base_link here (rviz). This is the TF tree: But when I run robot_localization, the localization is perfect but it doesn't show my sensor frames. There are also some warnings generated in rviz (check left pane), saying there isn't any transform to odom frame. But there is a transform as per the tf_tree. Here is a picture: How do I fix this issue? |

2017-03-24 10:33:30 -0500 | asked a question | Ros nodes not starting from a launch file 'm trying to create a launch file for starting all the nodes. But for some reason, running the launch file doesn't run the node. The topic in which the node publishes is listed when I run rostopic list, but when I try to echo, nothing is displayed. On the other hand if I just do a rosrun, it all works perfectly fine. This is my launch file: I'm using Indigo. I'm trying to launch a python node in a folder called scripts within the IMU_filter ROS package. |

My impression was based on the point cloud data, RVIZ will generate a map, but nothing happened. Am I missing something? |
