[FishBot教程] 9.0.6. 雷达驱动及建图测试
-
@2216096692 我和你有一样的问题呜呜呜
-
@2216096692 偶尔出一个timeout没事，能建图就说明数据没啥问题，另外驱动过后，需要开新的终端测试，看你的图好像退出后再用hz查看，但驱动已经退出了，肯定没有数据
-
保存地图出错
/opt/ros/humble/lib/nav2_map_server/map_saver_cli: symbol lookup error: /opt/ros/humble/lib/libmap_server_core.so: undefined symbol: _ZN9nav2_util13LifecycleNode18on_rcl_preshutdownEv
[ros2run]: Process exited with failure 127使用小鱼在B站分享的fishros2的fishbotU盘系统，而且我用一键安装指令重装了ROS2依旧报错。
-
@515261725 你有安装nav2吗，上下文操作有哪些？
-
@小鱼 鱼哥，我也有这个问题，每次都扫描开始一会就会timeout，然后就ERROR了，地图扫描不完整
终端如下：

雷达建图不是很清晰，感觉很模糊，是啥问题，如何解决
-
针对第四步，点云数据已经有了，但是Crtl+C，然后输入2之后，并没有产生建图，我遗漏了哪些步骤吗？

@1006076811 在 [FishBot教程] 6. 雷达驱动及建图测试 中说：
针对第四步，点云数据已经有了，但是Crtl+C，然后输入2之后，并没有产生建图，我遗漏了哪些步骤吗？
我明白了，需要在rviz2里再添加一个map的监视
-
我这 确实没有 /scan 话题
-
可以正常启动，但是过了一会就会显示failed to get scan 跳帽也转成wifi模式了，请问怎么解决，topic list中也没有话题 -
@1141682555
有时候也有报错
“Failed to turn on the Lidar, because the lidar is blocked or the lidar hardware is faulty”
