在ROS 1节点中,通常使用NodeAPI并实现它们自己的main功能。只有少数软件包利用NodeletAPI并将其组件编译为共享库。开发人员必须在这两个不同的API之间进行选择,并且从使用一个API转换到另一个需要一些非常重要的工作。In ROS 1 nodes commonly use the Node API and implement their own main function. Only a fe...
Network interfaces on a typical MicroK8s container Every Kubernetes pods gets its own IP address The Kubernetes network model asserts thateach pod receive its own IP address, and that pods within a K8s node communicate with each otherwithoutNetwork Address Translation (NAT). ...
Therefore, as long as the intruder node is able to join the communication domain where the target is located, it is able to steal the information of the target topic. Then, the intruder can steal the data like the ROS2 network structure, and may carry out further intrusion into the ROS2...
The topic we are really interested in this one:/wrist_rgbd/depth/points Let’s open rviz2 in afourth terminalso that we can understand things better by visualizing data like the depth information of the camera: rviz2 Rviz is a graphical tool, so, in order to see it, you have to click...
Another useful new rosbag feature new in ROS 2 Foxy is ability to compress and decompress bag files while recording and playing data. This can save disk space and bandwidth, both of which are in limited supply on robot systems. Similarly, ‘ros2 node –verbose’ and ‘ros2 topic –verbose...
