LogoBrutus

Your AI assistant,
with a physical face.

A Windows desktop agent that drives a hand-built robot head over Bluetooth. It listens, reasons, and speaks in sync.

It listens.

Whisper turns your voice into text on your own machine. No cloud microphone, no telemetry.

It thinks.

LLaMA 3 on Groq reasons over forty tools: your files, your mail, your research, your phone.

It speaks.

Open-source TTS streams the reply while servo lips sync to every syllable over Bluetooth.

Hand-built from sheet metal and servos.

Four micro servos move the eyes, eyelid and jaw. An Arduino Uno and an HM-10 module take commands over Bluetooth LE. Every expression you see on screen plays out on real metal.

Early servo assembly

Six expressions.
Twenty scripted moves.

Every emotion maps to servo keyframes stored on the Arduino, dialed from 0 to 100% intensity. The model triggers them mid-sentence as tool calls: say "Brutus, wink" and the metal face winks back.
