Automatic Naptime With BabyBjorn Bouncing Servo

A hobbyist built an automated rocking mechanism for a BabyBjorn bouncer using a Futaba S3003 servo, an Arduino Nano, 3D printed parts, and a string-and-spring mechanism. Two potentiometers let parents adjust bounce speed and amplitude independently. The design files are shared on Thingiverse, and a demo video with English audio accompanies the writeup.
