(我再次上传此内容,因为第一次没有人回答)我已经在装有 Ubuntu 20.04 的 Raspberry Pi 4 B 中设置了 ROS noetic。我想用我的 LiDAR 制作地图,所以我首先安装了 rplidar。但是,当我运行 roslaunch rplidar_ros rplidar.launch 时(在执行 source ~/catkin_ws/devel/setup.bash 之后),我的 LiDAR 开始旋转片刻,然后出现此错误:
[ERROR] [1700330979.765364372]: Error, operation time out. RESULT_OPERATION_TIMEOUT!

顺便说一句,那个所谓的日志文件并不存在。我使用的是 EAI YDLIDAR X2,波特率为 115200(启动文件也显示为 115200)。有人能帮我吗?
