Flutter-Powered Robot Butler
summary
A working robot butler runs on Raspberry Pi 4 with servos, LEDs, camera and mic while Flutter serves as the central brain. Local Whisper does speech-to-text, OpenCV handles vision, and an n8n agent plus an on-device LLM produce JSON action sequences (motor angles, LED states) that MethodChannels send to GPIO to move and speak. The demo is end-to-end functional but reveals surprising latency when asking for long action lists, so model choice and step granularity matter.
