To explain what is a ROS topic, I will use here a different approach from what you can already find on the Internet. Instead of giving you a bunch of code to write and run, I will use a real life analogy so you can easily understand the concept behind ROS topics. This post is a ...
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 the lowest, as its parent 并且被父母的水平替换它的水平加上一个。

When node A is started, it can add a new parameter into the parameter server. If node B starts after node A, node B will have access to this new parameter. Conclusion When you create a ROS master, a ROS parameter server is created. It contains a dictionary, accessible globally on the ...
This is how to recover data from Android through Google Drive. It is simple and fast. If you are used to turning on automatic synchronization, this situation is really a lifesaver.
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...
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.
A: The Pi is like an Arduino on steroids – more powerful CPU and OS, but lacks the precise timing and analog inputs of an MCU. The two are complementary depending on your specific needs. Q: How difficult is the Raspberry Pi for kids to learn on?
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 ...
In the realm of virtualisation and cloud computing, the hypervisor is a critical component that enables the seamless operation of multiple virtual machines (VMs) on a single host. While virtualisation is a technology, the hypervisor is its actual implementation. In this beginner’s guide, we will...
