Rviz shows no map #16

ming4now commented 4 years ago

i met a problem, i think the package is not compact? because when i roslaunch rrt_exploration_tutorial single_simulated_house.launch, i see no tf between /robot_1/odom and /robot_1/base_footprint, In rviz, TF is warning and Map is warning, no map received. ROSINFO shows:[ WARN] [1587870738.373049678, 2432.140000000]: Timed out waiting for transform from robot_1/base_link to robot_1/map to become available before running costmap, tf error: Could not find a connection between 'robot_1/map' and 'robot_1/base_link' because they are not part of the same tree.Tf has two or more unconnected trees.. canTransform returned after 0.1 timeout was 0.1. i tried to create a tf between odom and base_footprint, and i saw the map in rviz, but i can not still move the robot using arrow. dose anybody can help me ?or tell me how to figure it out, thanks

I got the same Issue while using melodic, it is currently giving me the following results on the terminal:- rrt_single_error

The TF is as follows frames.pdf Is having no connected from robot_1/odom to robot_1/base_footprint correct?

Note that, I got this by launching:- roslaunch rrt_exploration_tutorials single_simulated_house.launch and roslaunch rrt_exploration single.launch

Hello Everyone,

I am also experiencing the same issue with the tutorial's robot model. The errors are the same as @ikvibhav. It would be helpful to get any solution to this issue. It will also be helpful to know about the results of this work.

Thanks in advance.

Hi, it's weird that the transformation between the odom and base_link frames is not being published! which should be done by the robot driver (kobuki node)... I don't have this issue (on ROS kinetic). Many have reported this issue too, are you using ROS Kinetic?

hex-plex commented 2 years ago

@franklinselva you havent installed kobuki-destop which publishes the odom in simulators @hasauino you can add this package in this into a rosinstall file or in the package.xml.

franklinselva commented 2 years ago

@hasauino @hex-plex Hello. Thank you. I was able to solve this with some modifications in the ROS nodes of the rrt_exploration package. I will find the work again and if possible, I will add a PR too.

Since it is way too old, I hope I still have the work from my old computer. Will keep you posted. ;)

@franklinselva what modifications did you have to make in the ROS nodes of rrt_exploration package? @hex-plex installing kobuki-desktop from source worked.

franklinselva commented 1 year ago

@sandilyasg Now that you mention it, I might have made some changes to the package irrelevant to this issue. Sorry for misdirecting due to my poor memory. I suppose if installing kobuki-desktop from source helps, we can close this issue.

sorry, could you please tell me how to operate it more specifically
