The Sphere-O-bot painting robot
The Sphere-O-bot is a friendly art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to a large duck egg (4-9 cm).
The robot is based on the original design of Evil Mad Scientist
The Sphere-O-Bot is a simple 2 axis drawing machine that can draw on most spherical surfaces. You can use it to decorate balls or eggs. This design also features the regular JJrobots electronics (the same we have used in all our robots). So you can create this robot or any other just simply printing new 3D printed parts and uploading the appropriate code.
The original idea belongs to Evil Mad Scientist
The frame was designed by Attila Nagy
The Sphere-O-bot is adjustable, and is designed to draw on all kinds of things that are normally “impossible” to print on. Not just eggs but ping pong balls, Christmas ornaments, light bulbs, and (yes) eggs (duck, goose, hens…).
The Sphere-O-bot frame was designed by Attila Nagy and slightly modified by JJrobots. The pen and egg motors are high-torque precision stepping motors, and the pen lift mechanism is a quiet and reliable servo (SG90) motor.
