StartExploration and StartMapping not working with Nav2d and Turtlebot3

asked 2018-04-03 13:45:31 -0500 gravatar image

We are trying to execute Tutorial 3 using a Turtlebot3 robot and gmapping. The map is appearing in rviz and teleoperation is working. However, when we send the StartExploration command, the robot does not move. When we run StartMapping, the robot moves straight forward and then stops.

We've checked the rqt graph against the rqt_graph of Tutorial3 running on the stage simulator and the two graphs match how they should (all messages are being passed appropriately).

Any help would be greatly appreciated!

There is no error that is generated. After sending /StartExploration the goal is received, but there is no action. We ran a rostopic echo on /map, and nav2d_karto is not transmitting any data which is needed/used by RVIZ and the Navigator nodes. gravatar image  ( 2018-04-04 11:57:57 -0500 )edit

@Darby Lim please don't use an answer to ask for more information. This should be a comment. This isn't a forum.
