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

Introduction ROS2 21 Lectures is a series of introductory videos on ROS2 created by Guyueju, and many friends may have started learning ROS2 through these lectures. During the learning process, you might be running ROS2 examples on a virtual machine or PC, but if you have a development board like RDK X3/Raspberry Pi/Jeston Nano, it … Read more
Introduction In the era of software-defined vehicles, the role of middleware has become increasingly important. As E/E architecture gradually centralizes, the automotive software system has seen a coexistence of multiple operating systems, leading to a sharp increase in system complexity and development costs. To enhance the manageability, portability, configurability, and quality of software, it is … Read more
Today, we will explore how to develop a high-performance, precise robotic arm using Python and low-cost FPGA.

Hello, I am Little Fish who loves fish-flavored dishes in ROS. In the last section, we completed the measurement of distance at a specified angle. This section will synthesize it into a ROS LaserScan message and publish it to the upper computer through Micro-ROS, ultimately achieving visualization in RViz2. Hardware Development Platform For convenience in … Read more
