小车按键没反应前进后退左右转都没有反应网络能ping通wanghuan@wanghuan-virtual-machine:~/桌面$ ros2 run teleop_twist_keyboard teleop_twist_keyboard This node takes keypresses from the keyboard and publishes them as Twist/TwistStamped messages.

@andrew_liumuran 重启之电脑后打开再microros就可以了把 我是这么解决的

前面的键盘控制功能都是好的，但是启动rviz2时报错，启动界面闪退，请问下是什么原因？
sszb-wan@sszb-2:/mnt/c/WINDOWS/system32$ rviz2
QStandardPaths: wrong permissions on runtime directory /run/user/1000/, 0755 instead of 0700
Segmentation fault (core dumped) -
@591259845 哈喽，问一下解决办法

小鱼，请问在执行这条运行agent的指令时：sudo docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged --net=host microros/micro-ros-agent:$ROS_DISTRO udp4 --port 8888 -v6，请问这个micro-ros-agent镜像是通过docker在线下载并运行的，还是之前就已经下载好的镜像然后通过docker运行下而已？一直没看懂这个agent镜像怎么来的，如果在线的方式的仅仅通过microros/micro-ros-agent这个镜像名就可以定位到这个吗？这个是通用的官方文件是吧？？

@pst 有一个网站叫 docker hub

@andrew_liumuran +1求解决

小鱼您好，我在运行
sudo docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged --net=host microros/micro-ros-agent:$ROS_DISTRO udp4 --port 8888 -v6指令时，一旦我用新的终端窗口跑指令，原本的窗口就会出现以下报错
terminate called after throwing an instance of 'eprosima::fastcdr::exception::NotEnoughMemoryException' what(): Not enough memory in the buffer stream [ros2run]: Aborted请求小鱼帮一下解决问题

您好，我在笔记本的Ubuntu 24.04.1 LTS双系统上运行9.0.4，但每次开新的终端跑键盘，原本接收数据的终端就会内存泄漏。麻烦小鱼或其他大佬帮忙看看问题回复，在此非常感谢！ -
@小鱼
Ubuntu 24.04.1 LTS开终端
docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged --net=host registry.cn-hangzhou.aliyuncs.com/fishros/micro-ros-agent:humble udp4 --port 8888 -v6
开新终端
ros2 run teleop_twist_keyboard teleop_twist_keyboard原终端
