  • We will use a remote for the womping willow too! Amazing, right!!!!! :0 ;0 ;0 ;0 ;0 ;0

  • Goodbye namby-pamby "Muggles Seeking Magic"! Hello, drastically more amazing "There Goes my Broom"! Our idea is that you play a game (don't worry, it's one with two people, we don't want to encourage loner-ing). You try to get a glider/broom/thing into a hole in the womping willow (like the secret passageway to the shrieking shack in the Harry Potter books (if you haven't guessed yet, this is Harry Potter themed)) So, you shoot the broom glider with a launcher and use a remote control (hopefully, we haven't yet worked out the kinks of how in the world you program a remote control) to get into the hole. But that's obviously too easy, and the other person is mysteriously missing. Another person controls the Womping Willow's branches with strings that they pull up to get the branches up, and loosen the string to let the branches flop down. If the womping willow hits the broom down the womping willow guy wins, if the broom falls down because the glider can't hold up the womping willow also wins, and if the broom gets in the hole the broom wins. :)

  • You will be creating your presentation on the NuVu Platform.

    Things to do/think about:

    • Your presentation should be located in the Portfolio tab of your project.
    • There should be (1) post titled with The Name of Your Project with all of the slides.
    • You should have (1) post of a video of your project in action. Chances are people wont be able to see your work from and we can project a video of your project working.
    • All slides should have a title. You can add titles when editing the post
    • With the exception of the Title slide NO TEXT SHOULD APPEAR ON YOUR SLIDES.
    • Only (1) image per slide. Images should be uploaded directly. Make sure that the images aren't pixelated! NO GOOGLE DOCS!!!
    • Be sure to add your team members as collaborators and make the (2) posts Public.
    • Only one team member can edit a post at a time!
    • Presentations should be no longer than 3 minutes. PRACTICE!

    1st Post : Title this post the Name of Your Project

    Absolutely no more than 9 Slides!

    1 Title/Intention Slide. For build projects, describe the Problem and Solution. For conceptual projects this can be expressed as Intention/Solution. The slide should include the name of the project and a one sentence statement of both the problem and the solution.

    Segmented Vehicle
    Problem: Design a vehicle for a mountainous world with difficult terrain to traverse.
    Solution:  A segmented vehicle with a universal joint system handles mountainous terrain by conforming to the landscape.
    1-2  Precedent Slides
    • One slide to show conceptual idea. 
    • One slide to show mechanical or functional idea.

    1 Concept Sketch. This should be a clean sketch of your initial ideas. If you do not have a nice drawing or lost yours, create one now!

    2 Iteration Slides. These slides should show early prototypes of your design. Focus on big changes. You do not need to show tiny changes.

    2-3 Final Slides. These should show clean images of your final project (these should be taken in the photo booth).


    The text of your post should have a strong narrative that ties together the Why, How and What of your project through clear, cogent writing. Tell the story of how your idea was born, developed, and manifest.

    The text should include the following 2 items:

    1. A 1-2 sentence project description. 
    2. A 1-2 paragraph brief for your project based on the description below.. The primary purpose of the text is to explain, entice, and convince the reader that your project is amazing and important. Imagine your project on display in the Museum of Modern Art. The text of your post is hanging on the wall next to your work. In 1-2 paragraphs, a viewer should understand what your project is, why it exists, and how you made it. More importantly, the viewer should be interested and care. You will draw them into your project through a compelling narrative.

    Things to think about:

    • The what is a clear statement of the thesis or problem+solution.
    • The why explains how your project changes the world. It is the reason your project exists – what social issue is it engaging, who is your project helping, how does the project change the world, and what important social, intellectual, or technical questions does it raise?
    • The how briefly explains what technical prowess, innovative methods, or cool materials you used in your solution.

    Here is an example from Penelope the Pain-O-Monster:

    Pediatricians and other doctors find it challenging to collect accurate self reported information from children about their level of pain due to lack of communication skills, fear, anxiety, and discomfort. Traditional 1-10 pain scales do not fully address these issues, often leading to uncomfortable children and inaccurate symptom information. Penelope the Pain-O-Monster is a cute plush toy that uses integrated pressure sensors to allow children to express their source and level of pain through play.     

    Our previous project, The EmoOwl, helped children with autism to express themselves by translating motion into color. As we sought to expand our children’s health menagerie, we thought about making a different stuffed animal to help kids in hospitals. We quickly realized that the pain charts that patients used to express their pain could be made more interactive and easier for a child to use. We read that playing with stuffed animals can take the children’s mind off the pain so we created an additional “Fun” mode to distraction from pain and anxiety. The handcrafted stuffed animal uses force sensors in different body parts that light up from blue to red depending on how hard they are pushed to show the child’s pain level. It is our hope that Penelope will help sick children feel safer while providing more useful information to care providers. We anticipate that Penelope and the EmOwl will soon have many more friends to help improve healthcare for kids.

    2nd Post: Video

    Upload a short video showing your project in action. Do not count on your project working as you expect during the presentation.

  • Our world is mountainous with difficult terrain to traverse. The ‘Segmented Mountain Climber’ is able to deftly maneuver up and down the steep mountainsides, and over their sharp peaks. Its Whegs, half wheel half legs, are able to climb over both small rocks and large boulders. It can also quickly reverse, turn and is able to continue movement even if flipped upside down. 

    Our original idea was a mountainous world with difficult terrain to traverse. We started by brainstorming many different models that could help climb mountains. We decided on a segmented car which could work best in a mountainous situation by conforming to the landscape. It’s called ‘Segmented Mountain Climber’.

         During the first few days, we thought of various shapes for the vehicle, drawing inspiration from existing creations including roller coasters, snakes and trains. Then we brainstormed various designs for the wheels, including tank treads, legs, many small wheels, and large powered wheels.

         In order to better visualize the connections and turning of the segments, we made our first prototype of the large-wheeled model. In essence, it was just a trio of cardboard boxes tied together with string, with an axle and pair of wheels through each segment. However, some clear problems came up: the connection was not sturdy enough, and the wheels failed to rotate. We discussed at length how to incorporate the right wheels and connectors into our design. We started looking at other possible wheel choices, and then we settled on wegs. A weg is essentially a spoked wheel with the rim removed. Deriving its name from the words "wheel" and "leg," it could use circular motion, but with legs. Compared to traditional wheels, they could climb over obstructions and had superior grip. We also decided to replace the strings. At first, we had considered ball joints by virtue of their versatility, however we chose to nix the ball joints in favor of universal joints, because they could be better incorporated into the segments. Universal joints are basically two axles intersecting at a point, offering flexibility in two dimensions. Furthermore, the ability to transfer torque is exclusive to universal joints, so they could prevent any one segment from falling over. 

        Taking these considerations into account, we replaced the string and wheels on our prototype with universal joints and wegs. Upon finishing, we realized that the wegs in the prototype had the right structure but would not rotate because of the material (cardboard), the number of legs (4), and the structure of the foot. We decided that a 6-legged wooden weg would work better, and we redesigned the shape of the foot to include rubber that could provide traction. Another problem was the turning, we considered models such as rack-and-pinion, which was too delicate and complicated, and exploiting right-and-left rotation differences, which wouldn't work as well in a multi-car design such as ours. We decided on using a servo to rotate the first compartment relative to the others, turning the rest in due course. We didn't know, however, how we could incorporate the servo into the overall design. We decided that the joints would be included into the design of the car segments, and the servo would be attached to the foremost universal joint via a 3D-printed attachment. Unfortunately, a problem inherent to servos was the elimination of one of the two axes of rotation; as a result, the first and second compartments would always stay firm on uneven ground.

    Finally, after considering all these issues, we crafted the final product, learning from our previous errors. We used wood, which is much sturdier than cardboard; we used wegs, capable of scaling obstacles, and we used a servo to turn and manipulate the vehicle. We connected the motors and servo to an Arduino controlled by a remote. Overall, we had many separate design challenges; in the end, however, all the components came together to form a polished final product.
