Two step motors were attached to the mechanism to drive the two rollers. Those two step motors were controlled with a motor shield and Arduino UNO

The new mechanism worked well so I built a foam core mockup for the pad dispenser to house the mechanism. I used this model to test electronics, interaction, usability, and size.

This #2 prototype mechanism uses rotating motion for dispensing pads. The 3D printed gear shape rollers are designed with a specific form and spacing to hug the side of a pad. the housing was made of styrene. The required precision of those rollers was high, and the 3D printer had trouble to print the thin walls on the roller, so I used tape on the right side to add thicknesses and increase the grip of those rollers.

I created the thin fins on the roller with thin metal sheets because the 3d printer was having trouble to handle prints that are so thin. I designed those rollers with thin slots so I can slide those fins in them. Then I used those new rollers and rebuilt a new mechanism for testing.

Here is the #1 prototype functioning. the tension and pressure were hard to fine tune to achieve a consistent result. Furthermore, the mechanism that is required to push the pads down was too hard to be realized with the time we have to work on this project, so we moved on the explore better solutions for pad dispensing system.

Here is the #2 prototype mechanism in action. It worked well with some fine-tuning. Having longer fins on the roller will help to dispense those pads by increasing grip.
