What is the way to go in hobby robotics today? I'm more interested in high level, and want the lower level to 'just work' with minimum efforts from my side. Having mechanical part and vision what would be the right choice for low-middle software to control robotic arm and car, may be attached one to another. ROS2?

HuggingFace LeRobot. You can build the reference arm easily and cheaply and the software is designed to train AI. There's a lot to explore and extend there and the community is growing rapidly. It's based on the Stanford Aloha project. https://huggingface.co/lerobot

    LeRobot is 6DoF.

    How much does this matter in practice vs 7DoF arm?

      Probably not much. Also the LeRobot reference arm (SO-ARM100) is 6DoF, but it's very hackable and there are already project with different grippers, etc.

I’d say start with a sumo robot, line follower, or maze solver. That’ll keep you very entertained for a good while.

    Thanks, but no. It's going to be robotic arm with gripper and camera. The rest can be either Raspberry Zero (for cam, control, with net or blutooth, something big for high level). Another option, not exclusive, NVidia Jetson Nano instead of Zero. It could be Raspberry Pi 3, but I don't want to do video processing on it. All this I have, just need to put them together. Adding AGX Orin will be a big thing. That's actually the goal. With video processing and LLM all in one mobile robot. As it's hobby R/D it will be configured and reconfigured many times. That's why I don't want to do low level by hand every time.

    Another interesting option is Raspberry Pico * N + Tiny PC. For control and thinking. They can be connected via wifi or blutooth.
