V1.00

What animal is my design based on? Well 2 things one is real and the other is not. The real thing it is based on is the mototen of how a cat falls.

The unreal part is from a old game made in 20011, by a company called Valve. You might have heard of them, the game they made is called portal 2. In the game you have to solve puzzles, but in some of the puzzles you fall from very high and don’t die, this is because you have something called “long fall boots”

Now in the video they also say that they were very expensive, that's because they don’t break after a fall of over 1100 feet and not break or crack, so, if this were to be used to drop things from a plane, then it would require very expensive metals and plastics.

For this first design, all that matters was making a leg that hold the pressure of me pushing the leg down, and having it spring back up. In my first design, i would use string to accomplish this.

The quality was not that good though, and it felt like it would break at any moment.

V1.01

In this new version, I would use rubber bands instead of a string, so I took all of the string off of the cardboard and hot glued the rubber band from one leg to the other, this is what it looked like

I also add a smaller rubber band to keep the shocker in one position, so when it fell it would bend in one direction, and keep the small rubber band from bending in one direction, I hot glued it into a curve so it would bend in one direction only. 

V1.02

Cardboard lends itself to different mechanisms compared to wood and acrylic. This mechanism combines aspects of the parallel linkage and eccentric cam. It also uses the springiness of cardboard as the returning force to bring the flag back down.

Learning Goals: 

1. Understand the basics of the cam and linkage mechanism. 
2. Apply your understanding of the mechanism to create a unique prototype. 

Part I: Template model

Using the template file provided, you will create the cam and linkage cardboard model. To complete the activity, you will need cardboard, scissors or Xacto, a dowel or a pencil. 

Part II: Build your own version

Once you’ve completed the model, prototype at least 2 different ways to modify the pre-existing elements to: 

a) change the movement of the mechanism, 

b) customize components, 

c) introduce a new add-on feature, 

d) posit a novel application.

Deliverable

In the Responses tab above, make a post featuring 3 photos of your work (they can be process photos as well as final photos) 

In the text portion of your pot, make sure to describe the prototypes and explain your work process. 

Additionally, post your answers to the following reflection questions:

1. If you were to repeat this exercise, what would you do differently? 
2. Describe the parts you've modified from the original template. 
3. Are there other mechanisms you'd like to learn how to make?

If you have used the NuVu Platform before AND you remember your password, then skip to STEP 4 and 5. 

If this is your first time using the NuVu Platform or if you have forgotten your password, then follow all of the steps below.

-----------------------------------------------------------------------------------------------------------------------

STEP 1: In the top-right corner, click the word "login." 

STEP 2: When the black menu appears, click "reset password," and enter your school email address, and then click "Send Password Reset Link."

STEP 3: Check your school email account for an email from NuVu. Be sure to check your junk email folder as well if you don't see the email in your inbox. Follow the instructions in the email to reset your password.

STEP 4: You should now see your name in the top right corner. Success! (your screen will look slightly different than mine). Under "Studios" click on our current studio, "Cyborg Enhancements". You can also find this studio by clicking on your name in the top right corner.

STEP 5: You are now on the landing page for our studio for the rest of the term! To let me know that you have succeeded in making it this far, make a celebratory comment under the post "comment here!" This post will only appear if you have logged in successfully. 

Prompt

Feedback is a crucial step in the design process, as it exposes you to new ideas, methods, and techniques for developing your ideas further. Continuous feedback throughout the design process also creates a collaborative studio culture, where ideas are shared across projects, which leads to more exciting, developed, and innovative ideas!

We ask you to be thoughtful in your feedback, and refer to the guide below when giving feedback to your peers: 

Guidance for Giving Feedback:

1. Feedback should never have mean intentions! You can be positive and critical at the same time.
2. Be as specific as you can.
3. What kind of feedback would you find helpful if it were your project? Try to give the type of feedback that you would like to receive.
4. Always elaborate with WHY. Instead of just saying, "your idea is great," explain what part of their project you like, and why you think it is interesting.
5. Ask questions! If something doesn't make sense to you, ask a question about that part of the project or idea. This is a great method for getting someone to think about new ideas, different perspectives, and new approaches.

Instructions

In this assignment, you will provide feedback to three of your peers. To do this, go to the "Projects" folder, and explore your classmates' midterm presentations and initial sketch models. Select 3 other project teams to provide feedback to and create comments on their midterm presentations. Below their posts, click the "comment" button to add your feedback. 

Your peers (and you) will consider this feedback as they decide which one project idea to develop further in the next assignments. 

Mechanism Design 

Introduction

A mechanism is a system of parts that transform input forces and movement into a desired set of output forces and movements.

First, make a mechanism along with your teacher.  

Materials needed: 

• stiff paper or cardboard
• ruler
• cutting tool
• string (if you have it)
• paper clips, metal brads, and/or push-pins (toothpicks work too!)

Select and make 2 mechanisms that relate to your biomimetic motion activity.

PROCESS

• Elements Look at the diagram of the mechanism. How many elements does it have? How can you make these out of cardboard, popsicle sticks, or other found materials?
• Pivots Look at each element in the diagram more closely. How many pivot points or holes need to be made in each element? What kinds of materials can you use for pivots? (hint: brads, paper clips, and string are very helpful). As you work, pay attention to what parts must be allowed to rotate or move.
• Fixed Base All mechanisms require a fixed point of resistance in order to move. Can you tape or "fix" part of your mechanism to your cutting board in such a way that you can operate it with one hand?

These slides are just a starting point. Most mechanisms adapt and deviate from these based on their applications. Don't worry if your mechanism doesn't perfectly match the slides; focus on trying to make sure your input force creates your desired output.

DELIVERABLES:

When you are done making your mechanisms: 

• PHOTO Photograph your mechanism in its beginning and end states. (2 Photos per mechanism)
• GIF Upload your photos to EZGIF.com to make a gif of your mechanisms in action (2 GIFS). For best results, try to keep your camera in the exact same location for both photos. You may have to rig up a make-shift tripod.
• POST In the response slide, make a slide for each mechanism that has the two photographs and GIF.

Welcome to Arduino!

The first step in learning Arduino is to download the software.  This can be found at arduino.cc.  There are the step by step instructions in the images above.  

It is recommended to make sure that the install has worked by opening the arduino app on your computer.  In our next tutorial, we will go through how to use this interface and connect it to your physical Arduino device.

NOTE

If you have a chromebook, you will not be able to use this method and instead will need to create an account on Arduino Create to gain access to the web editor version.

These short Youtube videos demonstrate a wide range of cardboard carpentry techniques.
