Dot Bot - Bluetooth color marking bot

** REFERENCE ONLY: This version uses small DC motors that I couldn't synchronize well enough to make perfectly parallel lines (stepper motor version is in the works). Also, I haven't written a script/software to make it actually dot-out images. Sharing as-is for reference only. **


A bluetooth controlled mobile robot with four color markers. The original idea was to print a bitmap image by moving in parallel lines and dabbing/dotting Black/RGB colors as it goes. Like an imploded/inverted inkjet printer (Not intended to spin/plot). I haven't developed software to parse a BMP file and generate dot bot commands. I also haven't developed the ability to advance parallel lines with adequate accuracy. So at this point, it is WIP, but you can drive and draw "freestyle" or use scripts/macros (see video). I don't foresee any substantial electrical or mechanical changes. The car body shown will be a separate thing I'll share once I've printed the final version. I've tried to document the ass
