Reachy Mini app

A robot that
dances to your music.

Play a track and your Reachy Mini listens, finds the beat, and grooves along in real time. Bass moves its body, mids move its head, treble bounces its antennas, and a drop sets off a signature move.

What it does

A visualizer with a body

Screen visualizers pulse behind glass. This one sits on your desk and moves with the music.

Real-time beat detection

An FFT splits the sound into bass, mid, and treble and tracks energy onsets to catch beats and estimate the BPM, a few times a second.

Beat-synced dancing

Each band drives a part of the robot, and every beat punches an emphasis: a headbang, a nod, or a tilt, depending on the genre.

Genre styles

Electronic, Rock, Hip-Hop, Pop, Jazz, Classical, Chill. Each shapes how big and how smooth the moves are. Tune intensity and sensitivity live.

Drop reactions

A heavy onset triggers a signature move from the dance library that briefly takes over, then the groove picks right back up.

How it works

Three moving parts

01

Start a set

Pick a genre in the panel and press start. The robot wakes up and the beat spectrum lights.

02

It listens

It reads the bands and the beat from your audio input several times a second (mic, or system audio via a loopback device).

03

It dances

Smoothed, bounded motion follows the music, with a signature move when the drop hits.
