What it is
An expressive robot lamp inspired by Apple's ELEGNT research. Five motors move it, 24 LEDs light the head, and you can teach it a move by grabbing the head and moving it yourself: it records every joint and plays it back.
How it works
- Five STS3215 servos: base turn, base tilt, elbow, wrist roll and wrist tilt.
- 24 programmable LEDs behind a printed diffuser in the head.
- A Raspberry Pi with a microphone hat sits in the base.
- One stripped Ethernet cable carries both power and data up to the head.
What you need
- 5× STS3215 servos
- Raspberry Pi + ReSpeaker hat and an LED matrix
- Printed parts (3MF files)
- An afternoon of wiring
