[Python] Beginner needing help Armpi Pro (Hiwonder) – Arm not responding, want to integrate...

I’m currently working on my final high school project (Matura) using the Hiwonder Armpi Pro robot. I’m new to robotics and computer science in general, so I’m learning as I go

So far, I’ve managed to do the following:

• Set up a Raspberry Pi 4 running Ubuntu 20.04
• Installed and configured ROS2 successfully
• Connected the Armpi Pro and was able to control the wheels not using ROS2 (ROS2 is only for the arm)
• Organized the project structure and started experimenting with different ROS2 nodes

While I’ve made some progress, I’m currently stuck with a few things:

• I can’t get the robotic arm to move. I think the issue is related to the servo controller, or maybe I’m missing something in the ROS2 topic configuration
• I want to integrate an Orbbec Oradar MS200 LiDAR sensor, but I’m unsure how to set it up and use the data inside ROS2
• I also plan to use the built-in camera with OpenCV for object detection or simple tasks, but haven’t figured out how to combine that into the ROS2 pipeline yet
