There is no better way to learn electronics and robotics than building and customizing your own robot. ELEKS has shared a video that shows an Arduino powered Egg painting robot in action. You can build it using an Arduino Uno R3, 2 stepper motors, 1 servo motor, LEGO pieces, and 3D printed parts.
Just bring your egg-shaped objects, and this machine takes care of decorating it. Pretty cool, don’t you think?
