when i meet Error while "Running the code" #218

Closed wahihijames closed 2 years ago

wahihijames commented 2 years ago

I typing and start --> $ roslaunch geometric_controller sitl_trajectory_track_circle.launch

but I meet this error. To solve the problem, what should I do?

(설치 다 끝내고, 실행 시키니깐, 아래와 같이 에러가 나와요) 어디가 문제여서 발생한 걸까요?

Initiating shutdown!

Are you sure you have built PX4 SITL and run the sitl gazebo environment without using mavros?

Thank you Reply. I solved my issue. Although catkin_ws was already installed, it was installed again, and the path was tangled.

I have another question. $roslaunch geometric_controller sitl_trajectory_track_circle.launch When I run , all Gazebo etc. appear, but the drone is only arming and not taking off. (See attached video) What did I do wrong? The log file generated by QGroundControl is attached. please check.

catkin_ws가 이미 설치가 되어 있는데, 또 설치를 하게 되어서, path가 엉클어져서 생긴 문제 였습니다. 또 하나 질문이 있는데요. roslaunch geometric_controller sitl_trajectory_track_circle.launch 을 실행시키니, Gazebo 등은 전부 나오는데, 드론이 Arming 만 하고 있고, 이륙을 안하네요. (첨부한 동영상 참조) 제가 무엇을 잘못해서 생긴것일까요? QGroundControl에서 생성한 로그파일을 첨부 합니다. 확인 부탁드립니다.

@wahihijames Was the problem solved?

On the video it looks like the video has already crashed to the ground
