The Drawing Machine - Designing and Testing

Once we had a basic idea of what our machine would be, we started to build a prototype out of cardboard and bamboo. The structure itself was not very sturdy, which still became an issue in our final design. The gear system in our prototype was replaced with a cardboard disk with the paint droppers hanging off of it, to test if that system would work.

We tested it, and found a few problems:

-The leg and frame structure was not very strong.

-The paint was too thick to create a smooth line, instead creating drops of paint.

-The paint ran out too quickly.

-The paint dropper kept hitting the legs of the frame and causing a mess.

We decided to correct as many of these things as we could in our final design.
