Robot doesn't move

[Vineet Pandey]

Thanks for Creating this plugin interface!
I am working with this package and I am able to see the gazebo topic publishing on ~/cmd_vel_twist in gazebo (as shown in the screen grab), however the robot doesn't move. Should I use additional controllers or packages to work with this? Could you please provide some insight into how the twist inputs from this plug-in interface goes to the SimpleTrackedVehiclePlugin

Hey,

it looks like there is no namespace present in this gazebo topic.

A good starting point would be to look at the gazebo topics and see if the SimpleTrackedVehiclePlugin has subscribed to the right topic.

# list topics
gz topic -l
# get topic info
gz topic -i /gazebo/[world name]/[model name]/cmd_vel_twist

One workaround would be to set the ignition (=gazebo) topic explicitly to the namespaced topic:

[...]
     <commandIGNTopic>/gazebo/[world name]/[model name]/cmd_vel_twist</commandIGNTopic>
[...]

It was an issue with the namespace in the gazebo topic. Closing this issue.
