So, with ROS 2, we will design new APIs, incorporating to the best of our ability the collective experience of the community with the first-generation APIs. As a result, while the key concepts (distributed processing, anonymous publish/subscribe messaging, RPC with feedback (i.e., actions),...

As a result, while the key concepts (distributed processing, anonymous publish/subscribe messaging, RPC with feedback (i.e., actions), language neutrality, system introspectability, etc.) will remain the same, you should not expect ROS 2 to be API-compatible with existing ROS code. 但不要害...
From Tier IV we are looking at the following contributions initially, but we expect this list to change as we figure out more about our needs and resources. (Firm goal) Debian as Tier 2 platform (Fuzzy goal) Contribute to implementing deterministic publish/subscribe (coordinated via Real-time ...
Each topic is registered under a unique name and with a defined message type. Nodes can connect to the topic to either publish messages or subscribe to them. For a given topic, one node can not publish and subscribe to it at the same time, but there are no restrictions on the number ...
ros::Subscriber sub = n.subscribe("chatter", 1000, chatterCallback); 1. 最后ros::spin() 进入自循环,可以尽可能快的调用消息回调函数。如果没有消息到达,它不会占用很多 CPU,所以不用担心。一旦 ros::ok() 返回 false,ros::spin() 就会立刻跳出自循环。这有可能是 ros::shutdown() 被调用,或者是...
