鱼哥，编译告诉我空间不够了，有什么好用的办法腾出来？
-
@921203724 最好重新装下系统，分配大点空间

鱼哥，请问一下第三部启动 bring up 报这个错如何解决？

@小鱼 在 [FishBot教程]7. FishBot-Nav2导航测试 中说：
rosdep install --from-paths src --ignore-src -y -r # 安装依赖
这一步，先跑一次一键安装
-
@小鱼 謝謝,已解決

想要换自己的雷达 需要怎么操作
-
@1250372262 重点在雷达转接板，雷达转接板可以实现串口转wifi转串口功能，配合代码：https://www.fishros.org.cn/forum/topic/949/拓展-雷达转接板的无线串口功能驱动代码
-
@小鱼 我是需要把原来的雷达替换成新雷达 然后把无线串口功能代码烧进板子里面 还是 无线串口功能代码是在电脑使用 直接把雷达换了 这一块不是很理解
-
@1250372262 雷达板原有的固件不用动，配置上面给的代码就可以实现转串口了
-
@小鱼 这个代码是要放在雷达板还是电脑上 我现在雷达是有驱动的 这个驱动能在ros2正常用，我这个雷达如果插到雷达板了 驱动也是不能正常用，要是插在电脑上 那车上还得放个电脑么
-
@1250372262 雷达接雷达板，雷达板有无线功能把数据传输到电脑，电脑上运行我给的代码，会在本地形成一个虚拟的串口号，使用你原来的雷达驱动设置目标串口号为虚拟串口号，这样一个流程
