My first post here, and wanted to share an automation project to be used in the lab (I'm a chemist). The idea is to do layer-by-layer surface chemistry (http://pubs.acs.org/doi/abs/10.1021/acsami.5b00519). Since I don't have infinite amounts of time to dip a slide in jar after jar for hours on end, I decided to make an XZ robot using Firgelli linear actuators.
The project can be found here (http://limhes.net/?page=arduino_xz).
A video of the thing in action (PID still has to be tuned a bit :) ) found here (https://www.youtube.com/watch?v=_TlPnTOZ93w).
I tried to keep the source code kind of organized, so it should be easy to use the libraries for any project using Firgelli L12-P or L16-P linear actuators. I changed some of the libraries, so please use the ones you find on the project page.
OMG, it is so cool. I am a chemist too and I have a case about dip coating for industry. I have survey some machines but they are not cheap for me. I am not good at mechanical. Please give me tuition if you want it when you made it down.
