"원격접속을 성공하였다면 ls -la /dev/ 명령어를 사용하고 AHRS, BT, MW, YDLIDAR가 리스트에 있는지 확인합니다"
1. 이 부분을 실행했는데 AHRS만 리스트에서 확인이 되지 않고 있습니다. 하위파일로 추정되는 ttyUSB0만 확인이 되는데, AHRS 파일 내부에 속해있어야할 것 같은데 없는 것 같습니다.
블로그를 참고해서 sh create_udev_rules.sh 를 실행하고도 아래와 같이 리스트(마지막 참조)가 뜨고 있습니다.
/home/pi/colcon_ws/STELLA_N2_PI_X4PRO_ROS2의 stella 폴더 안에 stella_ahrs 폴더가 있습니다. colcon_build를 할 때 뷜드가 안되는 영역에 있다고 합니다. 또한 ls -la /dev/를 해보면 다른 센서들은 등록이 되어있는데 ahrs와 관련된 것은 아무것도 없습니다. stella_ahrs를 stella와 동일한 위치로 옮겨(stella_bring, stella, stella_camera, stella_description, stella_teleop_bluetooth와 동일한 level의 위치)보았지만 인식이 되지 않는 문제는 동일했습니다. (sdtella_md, ydidar_ros2_driver는 원리 stella_ahrs와 함꼐 stella 폴더 안에 존재합니다.)
2. 또한, 이후에 bringup launch 코드를 실행하면
pi@raspberrypi:~$ ros2 launch stella_bringup robot.launch.py
bash: ros2: command not found
pi@raspberrypi:~$ ~source /opt/ros/foxy/setup.bash
bash: ~source: command not found
pi@raspberrypi:~$
이렇게 뜨고 있습니다.
-> ls -la/dev 실행 후에 나오는 코드
pi@raspberrypi:~$ ls -la /dev/

어떻게 하는게 좋을까요? 저희는 STELLA N2 PI X4PRO 를 사용하고 있습니다.
저희가 2달째 sd카드도 다시 구워보고, 시도를 했는데도 되지 않아서.. 지금 구매하고 3달째 구동을 못하고 있습니다... 공모전 제출이 한달 남은 상황이라 방문을 해서라도 구동을 시켜보고 싶은데 가능한 방법이 있을까요? 답변 주시면 감사하겠습니다.

어떻게 하는게 좋을까요? 저희는 STELLA N2 PI X4PRO 를 사용하고 있습니다.
저희가 2달째 sd카드도 다시 구워보고, 시도를 했는데도 되지 않아서.. 지금 구매하고 3달째 구동을 못하고 있습니다... 공모전 제출이 한달 남은 상황이라 방문을 해서라도 구동을 시켜보고 싶은데 가능한 방법이 있을까요? 답변 주시면 감사하겠습니다.

안녕하세요.
아이디어 로봇입니다.
현재 AHRS가 인식이 되고 있지 않는 것으로 보입니다.
먼저 아래 링크에서 GUI를 설치하셔서 윈도우 PC에서 AHRS가 잘 연결되는 지 확인하여 주세요.
https://idea.synology.me/bbs/board.php?bo_table=forum&wr_id=33
테스트가 완료 후 문제가 파악되면 방문 수리 필요 여부를 확인하여 보도록 하겠습니다.
