[FishBot教程]9.0.7. FishBot-Nav2导航测试
-
鱼哥，我在执行这段代码：ros2 launch fishbot_navigation2 navigation2.launch.py
发生报错：
raise InvalidLaunchFileError(extension, likely_errors=exceptions)
launch.invalid_launch_file_error.InvalidLaunchFileError: Caught exception when trying to load file of format [py]: "package 'nav2_bringup' not found, searching: ['/home/jws/fishbot/fishbot/install/fishbot_navigation2', '/home/jws/fishbot/fishbot/install/fishbot_interfaces', '/home/jws/fishbot/fishbot/install/fishbot_description', '/home/jws/fishbot/fishbot/install/fishbot_cartographer', '/home/jws/fishbot/fishbot/install/fishbot_bringup', '/opt/ros/foxy']"好像是缺少一个功能包：nav2_bringup
后来我搜了GPT，执行了：sudo apt install ros-foxy-nav2-bt-navigator（运行成功了）
后来再回来执行：ros2 launch fishbot_navigation2 navigation2.launch.py
还是原来的找不到“nav2_bringup”包这个错误。
该怎么解决啊

@18296522393 建议用humble版本，另外需要单独装一下nav2_bringup，你可以看最新的视频或书，7.2章节有介绍命令。

@1683127550 请问解决了吗？

2d pose estimate 初始化不了怎么回事呢

@yongyong 把终端日志拿出来看看

@1634769990 你解决了吗

可以实现导航功能，但不准确。而且雷达会报error ,不知道有哪位大神可以指点如何解决。

@165437424 最近会更新下雷达驱动，这个偶尔出现一次没问题

@1250372262 在 [FishBot教程]9.0.7. FishBot-Nav2导航测试 中说：
建图都是没有问题的了 然后我按照导航测试那块 启动了fishbot_bringup 然后把地图换了，启动导航的时候地图能加载出来，但是点击2D Pose Estimate的时候，界面没有反应，不像之前那样了，并且也不能导航
也是这个问题
-
@2768003759 导航的时候雷达驱动，底盘驱动之类的都不能关闭，先检查各个话题数据是否正常，然后检查tf是否正常
-
@小鱼 鱼哥启动microros错误什么原因
之前都能成功 -
@法大 右上角搜 bind error ，你不复制粘贴，我就不帮你搜了
-
请问出现了什么问题 -
使用ros2 launch fishbot_navigation2 navigation2.launch.py use_sim_time:=False指令终端出现这个问题，用的是git下来的例程。在rviz2中使用2D POSE ESTIMATE也无法看见雷达信息和代价地图。
单独launch bringup_quick.launch.py文件
话题中没有robot_description话题，ros2 topic echo /odom没有返回消息，请问这是什么原因？ -
