Distributed Communication Intelligent robots have many functions. If all tasks are placed on one computer, it often encounters issues like insufficient computing power and lag. Wouldn’t it be better to break down these tasks and distribute them across multiple computers? This is what a distributed system does, enabling task allocation across multiple computing platforms. Distributed … Read more
In ROS2, both setup.py and CMakeLists.txt can be used simultaneously, but specific integration guidelines must be followed. For projects that contain a mix of Python and C++ code, the best practices are as follows: 1. Implementation of Mixed Builds 1. CMake as the Primary Build System (Recommended) Integrate Python modules in CMake using the ament_cmake_python … Read more
“I like technologies that are not easily replaceable, technologies that can still be used in the future, 20 years from now, that are simple and reasonable.” This simple technical declaration marks the starting point of Zheng Junjie’s journey into the open-source world and defines the direction of his subsequent explorations. Zheng Junjie’s Linux journey began … Read more
Introduction OriginBot is the first open-source smart car kit produced by Guyueju. At that time, I was an intern in the robot development team at Guyueju, and at the invitation of Teacher Guyue, I participated in the early OriginBot project group, responsible for developing content related to visual perception and planning control, as well as … Read more
Introduction With the development of robotics, autonomous driving, and industrial control, the demand for real-time and low-latency systems has become increasingly prominent. ROS2 (Robot Operating System 2), as the next generation of robot operating systems, provides better support for real-time performance, especially based on the DDS (Data Distribution Service) communication mechanism. However, ROS2 itself is … Read more

Following the previous two articles, we continue to work on navigation and obstacle avoidance for ground unmanned vehicles based on the RK3588 processor. Implementation of Fast-LIO Robot SLAM Indoor Positioning Algorithm with RK3588, ROS2 Humble, EasyMQoS, and MID360 Visual Power DIY Machines, WeChat Official Account: Visual Power Robot – Implementation of Fast-LIO Robot SLAM Indoor … Read more
To ensure stable and high-precision outdoor positioning, I started using a 3D LiDAR, the MID360 LiDAR.This LiDAR transmits point cloud data to the host via Ethernet, powered by an external 12V power supply.The implementation mainly includes the following aspects:1. Building the hardware unmanned vehicle platform2. Compiling the MID360 driver and testing it on RK3588-ROS2-Humble3. Compiling … Read more
