OctoArm A limb inspired by the way an octopus uses its tentacles to complete tasks, from walking on the ocean floor, to propelling itself through the water like a torpedo.

We made a prototype of an octopus tentacle out of cardboard and a series of joints. We decided to use different types of joints because we knew that would be the easiest way to make it move. We are exploring ways to increase the force that is exerted when the tentacle wraps around an object. We were resolving the problem we had with the sturdiness of the entire tentacle, we did this by taping popsicle sticks to the back of the tentacle to help support it. The characteristics we will keep include: the hooking motion, and using hot glue as a grip. We will have the same concepts, but different design. We will try to change the way it moves, we are thinking about using a rotating wheel type mechanism because the motion of the tentacle will no longer rely on the person pulling the string. For our next prototype, we will make sure to improve it in the best and most efficient ways possible. 

We had to create an abstraction of the Aurora Borealis, so we abstracted the colors and the movement to create an installation that responds to the movement of a person the way atoms in Earth's atmosphere respond to charged particles from the sun, creating the Aurora Borealis. 
We decided to create translucent boxes out of acrylic and put LED lights in them. The acrylic and the position of the LEDs diffused the light in a very beautiful way that was similar to the glow of the real Northern Lights. We wanted the boxes to move in a wavy motion like the Northern lights do, so we used a Servo to move a line of the boxes. 
 

The reason for our project was to create an abstraction that moves and had the same colors as the Northern Lights. We did this by using a Servo, acrylic boxes, and LED's to recreate the movement and the colors of the Aurora Borealis. In our project, we had a long wooden board that held up the boxes. On one end it had a screw, and on the other it had a Servo. The Servo was connected to one box, and it would move that box back and forth, therefore also moving all the boxes back and forth. At the same end as the Servo was the power strip and the LED's. The LED's went through all the boxes on the top, creating light that cast downward on the the person standing underneath. Also at the end with the Servo was a Ultrasonic sensor. The sensor would sense whenever a person went underneath our project, and would light up and and move only when triggered. At the beginning of our project, we didn't think hinges were necessary, but we later decided to use them. We created many cardboard boxes; some vertical, some horizontal; some with holes for LED's, some without; some with room to move the boxes ninety degrees, some without. It was a very long process, but because of our many iterations, our project came out well. There were some challenges, however. One, was that because we had been using cardboard the whole time, we did not account for how heavy the acrylic was going to be. The Servo had a hard time moving the boxes, and therefore our project had more of a stuttering motion, instead of a wavy one. A second challenge was that the soldering on our LED's was not good at all, so we ended up having to use just a strip of uninterrupted LED's, and cover up the lights that were showing.

For this iteration, instead of having just cardboard thinly cut in places, we created our first set of boxes. We used boxdesigner.com to make vertical boxes using notching. We attached the boxes using screws. We would put the lights down the sides of the boxes. We ended up not using this version for a few different reasons. One was that the motion was very limited, and it was not able to move in the wavy motion. Another, was that we decided the lights would look more realistic coming from the top, rather than the side. It would have more of a glow effect and be more representative of the Northern Lights. We changed a lot of features for the next iteration.

This iteration is one step before our final cut. We made the boxes horizontal and planned to have the lights coming from the top. There were still a few technical changes that we needed after this iteration, though. We had to alter the Rhino sketch to accommodate space for the top and bottom pieces so they didn't stick up as they do in this picture. We also made them more visually appealing by making end pieces and we added screw holes for the servo. The only other thing we changed from this version for the final was changing the box dimensions from cardboard width to acrylic width.

THE PRESENTATION POST

This post's privacy is set to Everyone. This post showcases your final design by telling the comprehensive story of how your idea was born, developed, and manifested. The arc of the story should encompass the, How of your project in a compelling narrative. It showcases your design process including your brainstorming, each of your iterations, and your final prototype. It allows the viewer to delve deeply into your process.

• Every Slide should have a Title and Caption.
  The body of this post is The Brief. You should include a version of the Brief for each collaborator in the project.
• This post will be used in your review presentation at the end of the session.

You are encouraged to make your narrative as compelling as possible. All of the content below should be included, but if you would like to rearrange the material in order to tell your story differently, work with your coach.

INTRODUCTION PORTION

Your presentation is a narrative, and the introduction sets up the scene for that story. Here you introduce the project, say why it is important, and summarize what you did.

TITLE WITH TAGLINE: This slides shows a crisp, clear final image and the title of your project. with a pithy blurb describing the project. The image, name, and tagline should draw a viewer in. 

Examples:

• The Fruit - A line following, light tracking robot
• Segmented Vehicle - A vehicle that conforms to the landscape
• Cacoon - Wearable sculpture exploring the concept of transformation and death

EVOCATIVE  IMAGE: This is a single image that shows a clear image that evokes the soul of your project. This image helps set up the why in a compelling way, sets the stage for your narrative, and will help frame the entire presentation. The caption of this slide (set with the Edit Captions button when editing your post) should discuss the context of your project. No Text on the slide.

THESIS STATEMENT: This is a TEXT ONLY slide for which briefly describes the Soul and Body of your project. You can use the project description from your Brief or write something new. This statement ties together your narrative.

Examples:

• The Cocoon:  A wearable sculpture that explores the concept of transformations and death. The Cocoon explores the spiritual journey beyond the human experience; what it means to be human, how wonder effects us, and the concept of what happens after death.
• Body Accordion: A musical prosthetic that translates the wearer’s body movements into a dynamic multimedia performance. The Body Accordion converts flex sensor input to sound through Arduino, MaxMSP, and Ableton Live. 
• Seed to Soup Animation: A whimsical animation about the slow food movement. Seed to Soup showcases a holistic method of cooking. From garden, to kitchen, to dinner table.
• Antlers: A wearable sculpture inspired by antlers found in the deer and antelope family. "Antlers" explores the comparison between armor and attraction. 

PROCESS PORTION

The Process Portion of your presentation tells the story of how you iteratively developed your project. Somewhere in that story you should include conceptual and technical precedents that guided you at each stage as well as brainstorming and process sketches and clear photo booth imagery for 3-4 stages of your process.

This portion is made up of three types of slides repeated 3-4 times. Each iteration in your process should include:

• PRECEDENTS:  Precedents are any projects that inspired you creatively or gave you technical guidance. These can include conceptual precedents and technical precedents. No Text.
• SKETCHES/SKETCH CONCEPT DIAGRAMS: These slides show your generative ideas in sketch form. These should clean, clear drawings. A sketch should show a clear idea. Do not simply scan a messy sketchbook page and expect that people will understand. If you do not have a clear concept or working sketches it is fine to make them after the fact. No Text.
• PROTOTYPE IMAGES:  These are actual images of the prototypes  you documented in your daily posts. These images illustrate your design decisions and how your project changed at each step. No Text.

FINAL PORTION

The Final stage of your presentation is the resolution of your narrative and shows your completed work. The use diagram shows how your project works and the construction diagram shows how it is assembled. Final photos show the project both in action and at rest. The imagery captures your final built design.

USE DIAGRAM: A diagram showing some aspect of the functionality. These can include:

• How one uses or interacts with the project
• The overall behavior of the project over time
• For a complex interactive project, this can be a clear diagram of the software behavior

MECHANICAL DIAGRAM:  A diagram offering insight on how the project is put together and functions technically.

• Ideally, this will be an exploded axonometric
• At minimum this can be a labeled disassembled photo  

ELECTRONICS or OTHER DIAGRAM: Additional diagrams showing some important aspect of your design. 

IMAGERY: The last slides should have an images of the final project. These images should be taken in the photo booth, cropped, and adjusted for contrast, brightness, etc. Images should include:

• An image of the project in use (taken in the booth or at large). This should include a human interacting with the project.
• Images of project alone. Include at least one overall image and one detail image.
• You can also use an image In-Use. 
• Consider using a GIF to show how the project works.
