After a long stretch of broken parts, lost chunks of code, misaligned pulleys causing spray cans to swing like Tarzan, and the occasional smoking circuit board and exploding components, TagBot tagged successfully and accurately for the first time.
To improve things further, the morning after its first big print, Thingiverse decided to feature the designs of the spray can body.
Soon to come is a beefier code-base running on the arduino, and improvements to movement code that have caused unexpected behavior at speeds required to avoid bubbling paint.
There will also be redesigns in the physical robot, mounting more and more of the components on the print head, making it easier to sell and put together as an inexpensive kit.
And to all the donors and my friends and family, thank you for your patronage and support.
As always, you can track updates periodically here at Kickstarter, the code at GitHub, photos and videos from the trenches at the projects Tumblr blog, and updates and new designs to the hardware at Thingiverse.
