At this stage, it's mostly playing around with the hardware and tools and getting familiar with the capabilities and limitations, and creating the "glue" parts that let everything work together. Integration work is the embodiment of the phrase "the devil is in the details."
I'm currently using a uArm Swift Pro from UFACTORY, and an AxiDraw from EMSL (which I happily purchased from a Canadian distributor, Solarbotics.) The support hardware and systems are all my own work so far, but it's nice not to re-invent the wheel with the rest of the robotics.
UPDATE: I make and sell clever little clay target hangers and as of Feb 18th, I shipped by first robot-written order! An important milestone! Buy one and get a robotically-addressed envelope!
