Overview
A Raspberry Pi dog built around personality rather than gait, with a moving head, wagging tail, touch sensors, sound direction sensing and a speaker. Like MechDog it has only two servos per leg, so its 12 servos add expression rather than leg freedom. SunFounder supplies LLM voice-chat examples for cloud models or a local Ollama model.
