在节点一节中,运行$ ros2 run learning_node node_helloworld报错,Package 'learning_node' not found 原因是没有正确配置环境变量: 编译成功后,为了让系统能够找到我们的功能包和可执行文件,还需要设置环境变量: $ source install/local_setup.sh # 仅在当前终端生效 $ echo " source ~/dev_ws/install/local_...
(): # 函数名固定,由ros2 launch 扫描调用 #创建两个节点的启动对象,其他启动项写法不同 motor_node = Node( package="atr_pkg", executable="Motor_node" ) Ultrasonic_node = Node( package="ssr_pkg", executable="Ultrasonic" #这里的节点名为你在节点.py中的节点对象 #也就是setup.py中entry_...
其中‘node_helloworld = learning_node.node_helloworld:main‘ 中node_helloworld标识节点名,learning_node.node_helloworld:main表示执行路径。 只需在此文件中声明节点名和路径即可。 C++版本 首先需要创建一个新的功能包,取名为 learning_node_c 或者 lea...
