The problem about gazebo_ros_demos
I have a problem about the package gazebo_ros_demos. When I use
roslaunch rrbot_description rrbot_rviz.launch
then
roslaunch rrbot_control rrbot_control.launch
it shows the warning:
[WARN] [1597821207.287022]: Controller Spawner couldn't find the expected controller_manager ROS interface` .
When I use
roslaunch rrbot_gazebo rrbot_world.launch
then
roslaunch rrbot_control rrbot_control.launch
it's ok.
And I compare the result of rosservice list
, it shows the former one doesn't have controller_manager . That's why ?
@HHHCMH, have you installed the needed dependencies:
Maybe you do not have one of these.
Thanks for your answer. But I had installed these package at that time. And it didn't work.
