You can use it <strong>to decorate balls or eggs</strong>. &nbsp;This design also features the<strong> regular JJrobots&nbsp;electronics</strong> (the same we have used in all our robots). So <strong>you can create this robot or any other just simply printing new 3D printed parts and uploading the&nbsp;</strong><a href="https://www.jjrobots.com/wp-content/uploads/2016/07/Ejjduino_ARDUINO.rar"><strong>appropriate&nbsp;code</strong></a><strong>.</strong></p><p>The<strong> original idea</strong> belongs to<strong> </strong><a href="http://shop.evilmadscientist.com/"><strong>Evil Mad Scientist&nbsp;</strong></a></p><p>The<strong> frame was designed</strong> by&nbsp;<strong>Attila Nagy</strong></p><p>The <strong>Sphere-O-bot</strong> is <strong>adjustable</strong>, and is designed to draw <strong>on all kinds of things that are normally “impossible” to print on</strong>. Not just eggs but ping pong balls, Christmas ornaments, light bulbs, and (yes) eggs (duck, goose, hens…).</p><p>The <strong>Sphere-O-bot</strong> frame was designed by <strong>Attila Nagy and&nbsp;slightly&nbsp;modified by JJrobots</strong>. The pen and egg motors are high-torque precision stepping motors, and the pen lift mechanism is a quiet and reliable servo (SG90) motor.</p><p>All you need&nbsp;to create your own&nbsp;Sphere-O-bot.
