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.
