Hi @delethai.mai,
in order to send action goals you have to make sure that:
Then you can send the goal by typing rostopic pub /“name_of_as_server”/goal after which you can press tab+tab to auto-fill the correct message and then another tab+tab to autofill the message structure, which you then can alter
If you want to know the type of message used by a topic you need to do the command:
rostopic info /name_of_the_topic
Then you will see the type of message used by the topic
I believe if change the instrction to this: rostopic pub /[name_of_action_server]/goal [TAB][TAB] would be more clear because I met the same problem.
