An Arduino-powered, 3D-printed dancing robot

Dancebot - The Dancing Robot

By Jason Huggins (@hugs)

Overview

In this workshop, you'll assemble a small, humanoid robot designed to dance. The moving parts of the robot are called "Bitbeam". Bitbeam is LEGO Technic-compatible, but made with a 3D printer. 3D printing is a beginner-friendly, low-cost, open-source alternative for creating mechanical robot parts.

Dancebot will have the following features:

• Swivel head side to side
• Rotate each arm up and down
• Bust a move.
