Brett and I spent a couple of hours brainstorming and trying to solve the paint delivery challenge for the painting robot project.
We are starting to converge a bit on a syringe system that uses a lead screw to move the piston to dispense the paint. A stepper would drive the lead screw. I haven’t figured out the paint volume for a square centimeter of work surface but it’s possible the lead screw can be driven direct drive or through a timing belt.
The syringes will be loaded by drawing paint into them from a bag of paint that has had all the air removed.
The paint will be delivered to a cylinder where a piston/stamp will move the paint to the work surface.
Well there’s that idea and a whole bunch more we worked on. We worked on some embodiment of the drawbot project as well.
