As you already know, you can write a node in multiple languages, using for example the roscpp library for C++, and rospy library for Python. Well, those libraries also include the Topic functionality. So, you cancreate a publisher or subscriber in any ROS supported language you want, direct...
在ROS 1的架构中,Nodelet和TCPROS/UDPROS是并列的层次,可以为同一个进程中的多个节点提供一种更优化的数据传输方式。ROS 2中也保留了类似的数据传输方式,叫做“Intra-process”,同样独立于DDS。 应用层 ROS 1强依赖于ROS Master,可以想象一旦Master宕机,整个系统会面临如何的窘境。但是在右边ROS 2的架构中,让人...
ROS stands for Robot Operating System. Even if it says so, ROS is not a real operating system since it goes on top of Linux Ubuntu. ROS is a framework on top of the O.S. that allows it to abstract the hardware from the software. This means you can think in terms of software for ...
aand replaces its level by parent’s level plus one. For example, node A receives the message from the sink, the sinkis parent of node A and node A’s level becomes to one. If more than nodes wit the lowest level can be chosen, node A chooses a node, whose number of children is...

Well, you have to know thatROS is language agnostic. It means that the subprograms you write (nodes)can be written in any language. Your application can thus have a node written in Python communicating with a node written in C++.
TheAuthenticationplugin is central to the entire plugin architecture defined by DDS-Security. It provides the concept of a confirmed identity without which further enforcement would be impossible (e.g. it would be awfully hard to make sure a given ROS node could only access specific topics if it...

Private cloud is a cloud computing environment that is exclusively dedicated to a single entity or a service. Private clouds prove to be more cost-effective than public clouds when running workloads in the long term and at scale.
My system is ubuntu 16.04lts, camera is realsense d435i, RealSense ROS v2.2.7, LibRealSense v2.54.1 and when i use the "roslaunch realsense2_camera rs_camera.launch" I got: [ INFO] [1689951428.123701106]: RealSense Node Is Up! terminate ...
