Chauncey is a Wrylon Robotical Flower Care Robot designed by Barry McWilliams and built by John Park. Due to certain regrettable events, full-scale production of the FLORABOT 3L-1G model, a.k.a. Chauncey, ceased in 1913. However, do not despair -- you can build your own fully functional, 3D-printed Chauncey.

Mk. I plans for building Chauncey were published in the excellent 3D Printing Projects book from Maker Media.

Now, this updated Mk. II Chauncey can be created using a CLUE microcontroller board running CircuitPython and the Bonsai Buckaroo add-on board to sense soil moisture levels and water your flower or plant using a small, submersible pump.
