Node::Advertise(): Error advertising a topic. Did you forget to start the discovery service? #10

Closed SSmarshal closed 2 years ago

SSmarshal commented 3 years ago

Hi，I am using gazebo9 + ros melodic(it seems that ubuntu18.04 does not support gazebo8 but ros melodic needs ubuntu18.04). And I launched the world successfully but when I run the following code: "rosrun unitree_controller unitree_servo" Nothing happens in gazebo. And the terminal says Node::Advertise(): Error advertising a topic. Did you forget to start the discovery service? And I do not know how to fix it? Any help will be appreciated! Thanks in advance!

Sorry guys for a long time no reply, something happened to me and it's been a long time since I made a quadruped robot. I think it was a very small mistake, like a misspelling of a word.

I have contacted my former partner. There may be a memory error, but it seems that the filename was mistyped-up when a file was called from the staris.world.
