How to Assemble and Program Otto DIY Bipedal Walking & Dancing Robot
Otto DIY is the world's most popular open-source educational biped robot. Designed with 3D-printed body shells, four micro servos, an ultrasonic eye sensor, and an Arduino Nano heart, Otto walks, sings 8-bit tunes, shakes its hips, and dances along to music.
1. Anatomy of Otto's 4 Servos
- Left Hip Servo: Controls forward leg swing
- Right Hip Servo: Controls forward leg swing
