For the final project I am building a surface/wall that is defensive bold or what have you… As a person nears it, it too challenges the user by getting closer to the user. It will be comprised of a set of triangulated surfaces that are pushed by a servo motor forward in the direction of the user… It’s depth is determined by how close you are to it. I have yet to determine what kind of a sensor to use because I think this will affect the design and I think I just need to make one component and work my way to the overall larger scaled version which may or may not happen by finals. Ideally the surface will protrude out in a defensive manner and when faced with the fact that you will not budge it will retract back to its original position and in effect tremble out of fear… I don’t know that I will get to this but that is how I imagined it would be. I have considered linking it to a processing sketch where perhaps the amount of time and the length or degree of angle would generate some kind of measured drawing but perhaps that is missing the point… or rather complicating life for the sake of complication…
Thus far I think I will need 16 servo motors, of course an Arduino, perhaps an Arduino Motor Shield. I may also need an electrical current higher than 12dc. I need to test some materials and the ways in which the sensor will be set within the structural surface. Or whether the surface is stretchy instead of a triangulated hard surface. Or whether this will be a surface at all…
First initial sketch depicting the surface and a possible way to engage with it by touching grass:
In this sketch [Images on the right] I am thinking of making this into smaller components. I even wondered if this moving surface could be covered in grass or moss or something soft. The sketched go so far as to describe the interior components and how some kind of motor would push these up or out. While sketching I also came to the realization that the solid or hard surface might need to sit on a more flexible surface. In this way when it collapses it can retain its integrity and bend up to form pinnacles or pyramids when pushed out by a motor.
In this sketch I am starting to think about the mechanics of motion that I can achieve with the servo motor we were provided in our kits.
With additional appendages the servo motor might prove to be sufficient. Though I am sure there are easier more expensive means.
How do we approach it? What is the overall effect? Though the final might not be as large as I hope it will be modular with the potential to grow into a large piece.
Other options to explore include thinking about the forms. Why triangles? Why not circles?
How is this built? What guides the moving parts or appendages up and through to the surface?
