@小鱼 好的.......

[小鱼]

@1281857896 nav2的配置也贴一下

[1281857896]

此回复已被删除！

[小鱼]

@1281857896 求求了，不要截图不要截图，手机上一点都看不清，还不好复制粘贴

[1281857896]

@1281857896 基本没改啥，主要use_sim_time全都变成了false,然后把地图的膨胀半径减小，小车底盘的半径减小

@小鱼 不好意思，这个没考虑到

[小鱼]

@1281857896 这个参数是哪里来的

[1281857896]

@小鱼 第17章建图与导航实践 fishbot导航实现 fishbot导航实现那块安装了nav2功能包，然后从功能包里复制出来的参数就这么多，我刚打开功能包确实是这些参数
复制的时候用的下面这个命令
cp /opt/ros/$ROS_DISTRO/share/nav2_bringup/params/nav2_params.yaml src/fishbot_navigation2/config

[小鱼]

@1281857896 你从快速上手教程里拷贝试试，或者直接用快速上手教程里的导航配置跑跑，看看能不能跑起来

[小鱼]

@小鱼 有些参数不一样
