agent 手动编译，不用docker，以及树莓派上使用micros-agent的方法

南京嵌入之梦

@小鱼
我在 unbuntu22.04 虚拟机上参考此方式安装 MicroRos Agent，编译失败

直接用您的一键安装 ROS2 ，已正常运行，现在想和单片机通讯，按照文章先尝试了 Docker 模式，提示 MicroROS agent 没有找到，担心是外网问题，看到有直接安装在本地运行的方式，便参照实施。

前几步均正常，到编译（colcon build）这一步时，出错，尝试了很多方式，最终现象停留在：
dq@dq-virtual-machine:~/Desktop$ cd microros_ws
dq@dq-virtual-machine:~/Desktop/microros_ws$ colcon build

Finished <<< micro_ros_msgs [1.67s]

似乎是少安装了什么，搜相关问题，按其不同方式做，均问化解，故在此请教，望版主抽空回复，谢谢！

@南京嵌入之梦
此问题已化解。
将ubuntu虚拟机重新安装，再一步步按照鱼香ROS的教程安装，虽说还是有点坎坷，但总算安装完成了，并且成功运行，可以接收到数据，只是不太圆满，遇到了新的问题，正常查找问题。

我是参考这个帖子将 microros agnet 安装在本地的。

顺利完成教程中第一个 MicroROS节点，并运行。
目前运行的现象是：

不知道有人遇到过吗？盼指点！

@小鱼鱼哥是不是用了树莓派，按照步骤来，把开发板弄成串行模式，然后雷达直接连树莓派，两个板子是不是都不用连WiFi了呀，只用树莓派连就行了

小鱼

@苛性钠zzz 是的，你好聪明

@小鱼小鱼，能启动microros_agent,都在一个WiFi下，ping的通也是udp模式，但是启动键盘控制后小车不会动是为什么啊，硬件也重新烧录了最新的，是不是PIO也要重新烧一下

小鱼

@2431039560 固件用的哪一个

萌新

@小鱼最新V1.2.3的配置助手二驱板烧录的，具体是这个https://fishros.org.cn/forum/assets/uploads/files/1736172779188-fishbot_motion_control_v1.7.2.alpha.241229.bin

小鱼

@2431039560 开关供电都正常吗，线连接是否正常，确认下控制命令是否发布出去了，比如开个新的终端订阅，小车的oled屏幕会不会闪烁

@小鱼其他的好像都是正常的，然后cmd_vel发送出去了小车好像没收到，小车不会动，屏幕的线速度也都是0

小鱼

@2431039560 agent用的docker版本的吗

小鱼

@2431039560 有没有设置什么DOMAIN_ID

萌新

@小鱼 docker版本的好像下载不了，docker用一键安装以后get镜像那里出问题了，然后启动是这样的

拉镜像：
Run CMD Task:[sudo docker pull ros:humble ]
Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

启动不了：
docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged --net=host registry.cn-hangzhou.aliyuncs.com/fishros/micro-ros-agent:$ROS_DISTRO udp4 --port 8888 -v6
docker: permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Head "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied

Run 'docker run --help' for more information

然后DOMAIN_ID设为了0，这里我看站内有树莓派的教程说默认是=0

@小鱼鱼，我把domain_id删了，然后docker也下好了，也可以启动的，但还是和之前一样，能发数据也能正常启动，小车也连上了但还是启动键盘控制后不会动，其他还需要配置什么嘛，要不要在PIO里重新上传一下

@2431039560 再试试docker的

sudo docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged --net=host registry.cn-hangzhou.aliyuncs.com/fishros/micro-ros-agent:$ROS_DISTRO udp4 --port 8888 -v6

@小鱼
鱼，用这个好像因为内核不是amd的不行，我是arm64架构的
