Open-source Expressive Robot Lamp

What it solves

LeLamp is an open-source robot lamp designed to create an expressive, interactive physical presence. It provides a hardware platform for exploring human-robot interaction through movement, light, and sound.

How it works

The robot is built using a 5-axis articulated arm powered by servo motors. It integrates a Pi Camera for computer vision, a microphone and speaker for audio interaction, and 24 programmable LEDs to display visual expressions. Users can record and replay custom movements to give the lamp personality.

Who it’s for

It is designed for makers and hobbyists with an intermediate skill level who are interested in robotics and interactive hardware. The build process takes approximately 8-12 hours and costs around $260.

Highlights

  • 5-axis articulated movement for expressive motion
  • Integrated computer vision and audio interaction capabilities
