OpenClaw is an open-source project that allows you to turn a Raspberry Pi into an AI agent capable of interacting with the world through a microphone and speaker. It uses Whisper for speech-to-text, OpenAI's GPT for reasoning, and Coqui TTS for text-to-speech. This setup enables the Pi to respond to voice commands and perform tasks, offering a customizable and privacy-focused alternative to closed AI assistants.
