While I'm putting the design for the OpenADR mop module together, I decided to do a quick test of the 3D printed pump I'll be using to move the water/cleaning solution from the internal reservoir to the floor. The pump I am planning to use is a 3D printed peristaltic pump from Thingiverse.

For my test setup, I used the another of the cheap, yellow motors that I powered the wheels on the main chassis and the brushes on the vacuum module to drive the pump. I threaded some surgical tubing from a full glass of water, through the pump, and into an empty glass. I then ran the motor off of 5V.

Overall the pump ran great, albeit a little slower than I anticipated. The next step is integrating it into the mop!

Thank you for the great logs!

I am also working on a FloorBot...  One of my biggest concerns is the direction/distance of the solution spray.  

Currently I'm leaning towards a gravity-fed moistening system, which would keep the cleaning pad moist, however  this system has its own set of problems...

I'm wondering if you had considered the spray direction as a variable for control?
