This tells the story of why and how Zusie was constructed. It is partly a log of my work for my own purposes, but hopefully it can provide some information for anyone who wants to make something similar for themselves. Perhaps I have made a few mistakes that you will be spared.
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.
