@1281857896 这是到雷达板

[小鱼]

@1281857896 速度还可以，看看rqt-tf-tree

[小鱼]

@小鱼 ros2 topic hz /scan 也看看

[1281857896]

@1281857896没法确定小车底板的ip地址

[小鱼]

@1281857896 到雷达还是主控板的，插上oled都可以看到的

[1281857896]

@小鱼

[1281857896]

@小鱼 这是雷达和坐标关系图，那个底板可能不是全部的程序，只是讲解部分的最终程序，所以没有IP显示这部分

[小鱼]

@1281857896 可以用我提供的完整固件，那个固件缺少了断线重连部分，偶尔会有bug

[1281857896]

@小鱼 等会尝试一下，好家伙，串话题了，刚才不是在那个问题吗

[小鱼]

@1281857896 odom到base_footprint部分代码应该有吧，里面有时间相关的操作。

可以把左边的+1.0上去看看

[1281857896]

@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
