Problem Statement
Design a system to open a door nob with a motor.

The initial design
Two cylinders coming together to grasp a door nob.

Experiment prototypes and tests need for design

 * Found the first prototype was to small to grasp the door nob. In order to size up the cylinder to the door nob, need to know the relationship between 3dtin and the makerbot. Took measurements of the printed prototype and did not find a relationship between the to machines
 * Took the measurements of the printed prototype (prototype one picture). In order to find the size to put into 3dtin, need to use the probability (prototype 2). The measurements can be found of the two pictures provided. Found that non of this matter because 3dtin does not control the size. The makerbot software is what controls the size.


 * Scaled prototype on makerware. Scaled X to 28.80mm, Y to 14.40, Z to 6.75. Picked these numbers because this was the actual length wanted. This worked and fit around the door handle. This is the final prototype. Cylinder 3.PNG
 * The two cylinders will grasp both sides of the door handle. In order to grab the door nob, there is grip tap found here. This will be put on the cylinders and on the door handle. In order to hold the two cylinders together there is two straps that will tighten and hold the two cylinders together. They are found here.

Next Steps

 * Find a formula for both machines.
 * Find the right measurements to put into makerware.
 * Design a way to connect the motor to the original design.
