These machines, commonly referred to as Egg Bots, have been around for a while. In fact, an early version dates all the way back to 1990! Since then, many versions have been created, some scratch built and some others using LEGO Mindstorms. I really enjoy the challenge of designing my own models, so here is my version, the EV Egg Bot! Instructions, program file, and notes for building your own can be found below. Other than the eggs and marker, all the pieces you need to build this model come in the EV3 Home Edition kit 31313.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
