## 推荐桌面版,比较推荐。
sudo apt install ros-foxy-desktop
## 安装时间可能较长,安心等待。
source /opt/ros/humble/setup.bash
echo " source /opt/ros/humble/setup.bash" >> ~/.bashrc
启动第一个终端,通过以下命令启动一个数据的发布者节点:
ros2 run demo_nodes_cpp talker
启动第二个终端,通过以下命令启动一个数据的订阅者节点:
ros2 run demo_nodes_py listener
如果“Hello World”字符串在两个终端中正常传输,说明通信系统没有问题。
小海龟仿真示例
再来试一试ROS中的经典示例——小海龟仿真器。
启动两个终端,分别运行如下指令:
$ ros2 run turtlesim turtlesim_node
$ ros2 run turtlesim turtle_teleop_key
sudo apt install python3-colcon-common-extensions
