Test Results Summary
The test plans documentation can be found be clicking on the link hereBun Holder Test
PRI: Katie Berus Rev:01 Date:3/27A "bed of nails" was created to stabilize the bun on the image creation device so that it does not move when the soldering iron moves across it.
Ice Pack Temperature Test
PRI: Scott Eisele Rev:01 Date:3/29The burgers will be stored in a cooler mounted underneath the burger elevator until they are ready to be dispensed. This cooler will be kept cold with standard ice packs, which can be re-frozen. The image below demonstrates a temperature reading of one Ice Pack, demonstrating its ability to reach the temperature our burger have been specified to be kept at (40 deg Fahrenheit) in our requirement.
George Foreman Motor Test
PRI: Scott Eisele Rev:01 Date:3/29The George Foreman grill will be actuated via a DC electric motor mounted to the 80/20 which supports the vacuum rail. A 12V DC motor was tested, to ensure it had sufficient torque to lift the grill lid. The linked video demonstrates the motor lifting the grill lid.

Subsystem and System
Improvements have been made on the subsystems and the entire system as a whole through this phase. The new additions and improvements are shown below.Bun Etcher
PRI: Katie Berus Rev:01 Date:3/27A plate has been created in order to hold the bun at the same height throughout the printing process. The final plate is shown below and the drawing can be found here.
Burger Elevator Status Update, Drawings, and Assembly Documents
A functional test of the burger elevator's actuation system was completed on 2/18/18. This test verified that the elevator's actuation will be slide with minimal play, and translate at a speed of at least 1.25" in 10 seconds.
https://drive.google.com/file/d/1EM5Lr--ttzm0t45zzEhKpKyLqZJCpLzr/view?usp=sharing
Since then, minimal changes have been made to the burger elevator. The burger elevator was mounted to the working table via 4 socket head cap screws. In addition, a cooler was mounted to the table underneath the elevator to manage burger temperature.
This subsystem is fully complete, barring final adjustments to flag positions which will be completed once the grill and spatula systems have been installed. Additionally, one cutoff sensor still needs to be mounted and wired. Scripts to allow the RasPi to operate the elevator are also in progress.

Grill Status Update, Drawings, and Assembly Documents
This subsystem utilizes a George Foreman grill as the method of cooking the burger, so of the three mechanical subsystems responsible for burger cooking, the grill subsystem has the lowest overall risk level. The primary focus during this phase has been the other subsystems. 3D printed parts have been fabricated.In addition, a test to ensure the motor selected will be able to lift our grill lid has been performed. This is outlined in section "Test Results Summary" subsection "George Foreman Motor Test."
An additional 3D printed part was necessary to allow the string to spool around the electric motor's shaft. This part is known as the "Spooling Disk" and is shown in the photo below.

Spatula Status Update, Drawings, and Assembly Documents
The burger pusher remains the last subsystem required to meet the "burger cooking" function of our overall design. The actuator has been mounted to the table. The burger pusher will be fabricated and installed in the next phase.

Pick-and-Place System Update, Drawings, and Assembly Documents
When originally designed, the pick-and-place system used a 1/4" vacuum tube connected to a vacuum cup. When it was determined that the vacuum source could not provide enough vacuum pressure but did provide a high flow rate, the system was redesigned to use a 1 1/4" hose. This hose is large enough that it needs to be offset to the side of the vertical actuator. Redesign of the pick-and-place system allows for the larger hose to be used, but also applies a moment to the system due to the loading being off axis to the horizontal guide rail. Remaking the rollers out of aluminum to increase stiffness and provide smoother rolling in the guide rail was completed.
Last phase overall completion: 65%
New overall completion: 75%
Bun Hopper Status Update
The bun hopper is installed in the table using a simple flange. A linear actuator is mounted to the bottom of the tube. A piston will be fabricated and mounted to the end of the linear actuator, acting as a piston in a cylinder with the linear actuator driving the buns upward.
Last phase overall completion: 10%
New overall completion: 75%
Assembly Station Status Update, Drawings, and Assembly Documents
A problem we encountered in the last phase was there is not a wide enough path for the burger to slide when the station was assembled. 2 bolt heads securing the base act as an obstacle. A removable plate was fabricated with a u-shape tab at the end to ensure it will not slide when delivering the burger and a ramp in the front for the delivery.
Height adjustment of the station will be done in the first week of next phase and followed by the final assembly.
