In the past few months, we have covered a bunch of interesting eggbots that can decorate your eggs for you. Want to build your own? As the ELEKS team has demonstrated in this video, you can do so using an Arduino UNO R3, 2 stepper motors, 1 servo motor, LEGO pieces, and 3D printed parts.
The robot simply draws beautiful patterns on egg-shaped objects. More info is available here.
