      标题：fishbot雷达建图中断

      提问：使用激光雷达进行测试建图时，开始建图不到一分钟出现报错，建图中断

      问题描述：

      具体细节和上下文：

       ) 驱动雷达
2) 建图测试
3) 退出

      尝试过的解决方法：

      1、重新烧录
      2、更换新的雷达及转接板

      以上方法均失败

            ubuntu使用的是20.04和ros2(foxy)
            雷达是原配雷达，不是其他型号的雷达
            Firmware version: 1.5

            Model: S4
            Serial: 2020101300002268
            网络是桥接模式，使用的笔记本电脑开的热点。
            （后面更换Ubuntu22.04 ROS2 Humble 后仍然有这个问题：建图中断）

            配置好驱动后，进行建图测试，开始建图后，会出现

                @mixllred 在 fishbot雷达建图中断 中说：

                网络是桥接模式，使用的笔记本电脑开的热点。

                很想给你画一张结构图，虚拟机用桥接，笔记本开热点，你观察下小车的ip地址和虚拟机的ip,你肯定会发现两者不在同一个网段里。

                小车要想把数据发送给虚拟机（假设桥接模式），需要经过这样一条链路：

                小车-->电脑主机(中间还有网卡转发，更加耗时)-->路由器-->虚拟机

                如果是小车直接连接路由器，电脑桥接或者不是虚拟机，正常链路是：
                小车-->路由器-->虚拟机

                可以找客服要一个常见问题解答视频，里面有关于网络的详细介绍。

                    @mixllred 从ip可以看出都不再一个网段里，而且无法直接ping通。符合我提供的不推荐的网络结构，还不如直接让小车连路由，过电脑是多此一举。

                        @mixllred 原来是校园网，校园网质量是非常差的，你能跑起来就是万幸了，建议买个二手路由器，十来块钱，非常好用。

                          @小鱼 是笔记本通过有线网卡连接到路由器上，然后路由器（不上网）相当提供一个局域网吗？因为校内网线接口都需要登陆，连接路由器十分困难
