Remote control: Code runs on the Pi. A laptop connects over SSH or VNC to run the Python examples, and keyboard-control and web video examples are included.
Overview
A Raspberry Pi car with car-style servo steering, a pan-tilt camera and a small speaker, aimed at learners moving from blocks to Python and computer vision. SunFounder documents a long run of AI lessons, including local Ollama models, online LLMs such as GPT-4o-mini, offline Vosk speech recognition and an OpenClaw agent that drives the car. The main limitation is that the Pi is sold separately, and the heavier LLM projects need a Pi 4 or 5 plus an API key or network connection.
