일단은 micro HDMI 연결해서 시도.

 

다행히 x11 forwarding으로 되네. 모니터 안달아도 되겠다

ros2shell ros2 run turtlesim turtlesim_node ros2 run turtlesim turtle_teleop_key

 

하라는 대로 해보면 아래처럼 나온다.

ssh로 해서 귀찮아서 백그라운드로 돌리고 쑈하는 중

G(gola), B(?) 누르면 아래처럼 메시지가 나온다.

실행하면 먼가 나오는데

(ros2 galactic py3)er@er:~$ rqt_graph

 

hide 쪽 다 끄니 먼가 좀 나온다.

 

아니면 위에 topic을 적어주면 먼가 나온다.
