README
README.mdTopiary TrimBot
Have you ever seen a sculpture made not of stone or ice, but a living, growing plant? Topiaries are a common feature of lavish gardens staffed by professional topiarists, but are often out-of-reach of the amateur gardener or homeowner. Enter the Topiary TrimBot, an automated platform for creating your own custom topiaries. A bush is placed in the machine and then the user inputs their desired 3D shape. The TrimBot will then automatically detect the current plant shape, generate a plan for trimming it into the desired shape, and perform the required cutting. The user can then practice maintaining and refining the shape via hand-trimming, helping them to learn the art of topiary!

Questions
How big is the Topiary TrimBot PCB?
It measures 190.5 × 160 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Topiary TrimBot use?
285 parts, built around the MX25L51245GZ2I-08G, STCS2ASPR, TPS62933DRL and BSC050N04LS G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Topiary TrimBot KiCad files?
From the griffinross2/Topiary-TrimBot repository on GitHub, at the commit this page was made from: the board is hardware/PCB/TopiaryTrimbot.kicad_pcb and its schematic hardware/PCB/TopiaryTrimbot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Topiary TrimBot design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
