I don’t know my trench digger designs well enough to know if this model is based on a real-world machine or not, but I do know my Meccano machines well enough to know this thing is amazing!! The range on this thing is incredible, as well as the multiple simultaneous mechanical functions – it must have taken some time to design and build:
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.
