属于MutuallyExclusiveCallbackGroup的回调函数将顺序执行(即同一时刻只会有一个回调函数在执行),而属于ReentrantCallbackGroup的回调函数则可以并发执行(即同一时刻可以有多个回调函数在执行)。 3. 举例说明如何在ROS2中设置和使用不同的executor与callback_group 以下是一个简单的例子,展示了如何在ROS2中设置和使用不同...
ROS2 的 node如果不添加到spin中,则timer、service、action等的callback函数无法正常回调。 但是如果在service、action调用之后,调用如下函数则可正常回调。原因是spin_until_future_complete函数内部会创建一个executor,把当前Node添加到executor中 rclcpp::spin_until_future_complete(this->get_node_base_interface(), ...

In this ROS2 tutorial I will show you how to use an rclcpp parameter callback, so you can dynamically change parameters’ values while a node is alive.With parameters you can already change the configuration of the node at runtime.

ROS2开发BUG记录:在将 use_sim_timer 置为 true 时,节点的 Timer_Callback 行为“异常” 问题: 在将use_sim_timer置为true时,节点 Timer_Callback 行为 “异常” 。在回调函数中,使用self.get_logger().info("xxxx")输出信息,希望通过查看 Info 中的时间戳(如下),测试 Timer_Callback 回调频率是否正常。
@matthijsramlab this kind of questions are usually better suited for answers.ros.org, where the community at large can help you and others can benefit from that exchange. I encourage you to continue the discussion over there. For the time being, I'll close this as it's a non-issue. Wh...
