USB Egg-Bot CNC Art Robot
The Eggbot is an open-source art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to that of a small grapefruit.
The Eggbot is super 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, light bulbs, mini pumpkins, and even things like wine glasses. The egg-bot is ideal for Easter and a fun way for kids to make elaborate designs on their eggs.Â The egg-bot is recommended for ages 10 and up with parent supervision at 13 and under.Â In the photos, you can see just a few of the things you can do with eggs.
The Eggbot chassis is made of tough fiberglass, with integrated heat sinks for the included motors. The pen and egg motors are high-torque precision stepping motors, and the pen lift mechanism is a quiet and reliable servo motor.
The Eggbot kit is easy to assemble in a couple of hours, and only requires a couple of basic tools like miniature Phillips-head and flathead screwdrivers. You’ll also need a computer with an available USB port (Mac, Windows or Linux).
The EBB allows your computer to directly control the stepper and servo motors. The onboard 16X microstepping driver chips along with the 200 step/revolution stepper motors give a combined resolution of 3200 steps/revolution in both axes. A universal-input plug-in power supply (9 V 1.5 A) is included with the Eggbot kit, as is a USB cable.
Drawing on a ping-pong ball The Eggbot is normally controlled through a set of open-source extensions to Inkscape, the excellent, popular and free vector graphics program.
Basic operation is much like that of a printer driver: you import or make a drawing in Inkscape, and use the extensions to plot your drawing onto whatever object you’ve mounted in the Eggbot. It’s all handled through an easy to use graphical user interface, and works cleanly on Mac, Windows and Linux.
The Egg-bot isn’t a cheap toy, but it’s not a simple one either, so I see the value in the $195 purchase.Â The question now becomes, do you?
