The Marbling Octobot is a robot that is inspired by an octopus. Octopi squirt ink when they are threatened by a predator. It is their defense mechanism. The Marbling Octobot uses that defense mechanism as its  inspiration behind the project. 

The Octobot marbles paper by squirting ink onto water. Once it squirts ink, a comb, combs through the water, creating a beautiful marbled pattern. After, the user slides the robot off the tub of water and places a piece of paper on the water bath and pulls it up. This transfers the ink onto the paper, creating a unique piece of art.

The robot squirts ink by fulling it's syringes up with ink and then expelling the ink. The syringe intakes and outputs ink because the top is connected to a servo. Each servo is programmed to move between 10-30 degrees which expels the right amount of ink that a dropper may expel.  The servos are programmed to expel different amounts of during each process. The reason for this is to create a robot that makes a unique piece of art each use.
