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

Hello everyone, I am the little fish writing this blog while listening to the Great Compassion Mantra. Recently, I moved, and my girlfriend asked me to clean up my electronic waste. I found an old Raspberry Pi in there. It’s not that old, just a Raspberry Pi 3B from two or three years ago, but … Read more
This blog post mainly records my learning and understanding of the OriginBot camera driver and visualization (http://originbot.org/manual/camera_visualization/#ros) code, and I will annotate it in the code files. The documentation (http://originbot.org/manual/camera_visualization/#_2) provides two methods for driving the camera: one method allows real-time display of images and results of human detection algorithms (https://developer.horizon.ai/documents_tros/boxs/function/mono2d_body_detection) through a webpage after … Read more
Using a depth camera to capture images, YOLO detects human bodies and can be configured on the Raspberry Pi 5, suitable for various small to medium-sized robots. Configuration Raspberry Pi 5 ROS2 Jazzy Intel RealSense D405 Depth Camera YOLOv8n Model Using 30 Fps, it is recommended to change to 6 Fps on Raspberry Pi 5 … Read more
