introduction

FABMOBx303

  • Objective: transform a 3d printer into a machine for physical data visualization. Develop a Reprap printer’s inherent potential for expansion, connectivity and mobility; through the synthesis of the system’s hardware, software and mobile networks, create an integrated platform from this assemblage of seemingly disparate technologies.
  • FABMOB (fabrication + mobility) is both a connected and mobile object, a sensor and a transmitter, a prototype and a platform. FABMOB can transform the atmospheric data collected here and now into a physical object that forms a representation of that data. The physical object that is fabricated by this machine/prototype, is a…
  • ATMOStag (atmosphere + tag) is a tile printed by a FABMOB. The surface of this tile, through its unique topography, represents the synthesis of this captured data. ATMOStag serves to a mark (or tag) a territory; it can also be used to compare the flux in an atmosphere, or the atmospheric changes of a place measured through space and time.
  • The data captured by a FABMOB in its immediate environment includes:
    • the time, location and date
    • ambient light
    • humidity
    • temperature
    • CO levels
    • NO2 levels
    • noise
  • ATMOStag, made by FABMOB, is a project:
    • ATMOStag is an avatar of contemporary urban communication.
    • FABMOB is a project addressing the cultures of creativity concerning fabrication, makers and hackers. It’s multiplicity of potential applications does not hide behind the myriad of nomenclatures construed to justify the surveillance society, the Smart City or the automation of the built environment.
    • FABMOB simple goal is the expression of contemporary culture — networked society — as a gesture through public design.
    • ATMOStag marks an instant, the passage of time, as an atmospheric quality.
    • ATMOStag is an expression of contemporary culture’s convergence between:
      • data + real experience,
      • technology + nature,
      • science + art,
      • virtual + physical — through the fabrication of a personal, physical artefact emanating from that culture.
    • ATMOStag is the new ornamentation for the spatial design of the contemporary city. Neither decorative nor superficial, but ornamentation that is the modulation of a surface in order to reveal its depth.
    • FABMOB : ATMOStag is accessible to everybody through a CC license.

  • Défi Data+, is an “international challenge for the development of *functional prototypes* around digital manufacturing and connected objects, capable of creating tangible representations of data.” FABMOB: ATMOStag is presented in the context of this challenge.
  • Data: the data collected by FABMOB is freely available on the Smart Citizen platform:
  • Smart Citizen is the platform used to capture local data. It’s hardware design is based on the Arduino controller, as is the Reprap 3d printer; this accounts for their potential integration. Smart Citizen was developped at the Barcelona Fablab. Its financing was crowdsourced on Kickstarter in June 2013.
  • Blender is an open-source, multi-platform 3D computer graphics software product used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games. It is a program written in, and extensible by, the Python programming language.
  • Reprap is an initiative to develop a 3D printer that can print most of its own components. RepRap (short for replicating rapid prototyper) uses a variant of fused deposition modeling, an additive manufacturing technique. As an open design, all of the designs produced by the project are released under a free software license, the GNU General Public License.

functionality

FABMOBx18b

This description of FABMOB’s functionality is explained from the point of vue of its dataflow, the movement of information in the system:

  • 1 – Smart Citizen, the data sensor: is an open source platform for data capture and visualization, composed of Arduino comptible hardware. Smart Citizen’s objective is to “serve as a node for building productive and open indicators, and distributed tools… The Smart Citizen project is based on geolocation, Internet and free hardware and software for data collection and sharing (api, Mobile App and the web community). Data is relayed in real-time via wifi or 4G network to the Smart Citizen site. This data can be viewed on the website, saved CVS, XML or JSON, or accessible formats directly integrated API. The Smart Citizen is energy autonomous thanks to its rechargeable battery solar panel.
    • Link to the FABMOB Smart Citizen geospatial interface. Smart Citizen
  • 2 – Blender-3d + python, form and information: This open- source software is for creating 3-D digital models. Python is a programming language and integrated scripting.
    • tiles: in Blender, a model is prepared to receive the data that will geometrically transform it. A primitive cube (80 x 80 x 10mm) whose surface (or mesh) is prepared to receive these changes. Each tile at this stage, is identical.
    • measurement: A grid is employed that permits the comparative reading of the data and provides the information needed to link all the tiles.
    • data-points : each category of data (temperature , humidity, light , NO2 , CO , noise) is connected to a type of 3d transformation.
    • transformation: the data is linked to Blender via the Smart Citizen API and Python scripts. A quantity of data is correlated to a unit of transformation in Blender : the tile’s geometry is thus transformed to represent this data.
  • 3 – STL, a 3D format: The STL file format describes the surface geometry of an object in three dimensions and is used by 3D printing software. The STL file is written by Blender.
  • 4 – Cura, preparation to print: is open source *slicer* software to transform the 3D file (.STL) into a printable Gcode. The interface of Cura shows the successive layers of the model, follows the printing process and allows the control of its quality.
  • 5 – Materials, color, quality & meaning: the qualities of a printed object are color, flexibility, transparency. The choice is made with respect to the installation of a tile:
    • interior or exterior
    • man-made or natural
    • installed or embedded
  • 6 – Fabrication, physical visualization: the file generated by Cura is communicated wirelessly (wifi or 4G) to the 3d printer. FABmobs is a RepRap printer type, based on an open, assembled and modified source code for this project.
  • 7 – Mobility : FABMOBS is the contextual expression of local atmospheric data. The digital data stream is generated by mobile networks, or fixed without son. The mobility of our connected object, to which the base is a 3D printer, requires a source of electrical energy. This is ensured by a 100% electric car, no noise, odorless CO2 emissions (which will therefore not have a negative influence on the captured data) and available as a free service through the Ile de France region.
  • 8 – Self-replication: As with all 3d-printers that use the RepRap model, the device aims to be a machine capable of self-replication. We can produce 50% of its parts with another 3d printer, with the remainder of the components cheaply available everywhere. Here is a link to the plan drawings used to laser cut a FABMOB.

FABMOB platform development

  • Rules of Transformation for an ATMOStag: The generation of the surface of a tile is related to the geometric transformation in the Blender. It represents the level (rate) of a quality captured in a local atmosphere, or – light, humidity, temperature, CO, NO2, noise. Each quality is associated with a geometrical transformation rule. The data captured by the FABMOB rate determines the size of each transformation. Here is a graphic of these transformations air quality:

  • GEO-LINK/back: the network of ATMOStag tiles. The information embedded in an ATMOStag tile can be decoded via an engraved URL.” will allow the connection to the stream capture available on the platform and Smart Citizen access to a database ATMOStag, bringing 3D supplementary and complementary information (model , CVS …).
  • ATMOS-SD: through the use of a microprocessor development board (such as an Intel Edison) inserted into the SD socket on the 3-D printer for direct communication between capture, Blender calculates and 3-D printer.
  • ATMOS-AR: layer of consequential data that is available online and/or through mobile systems of augmented reality.
  • ATMOS-MAT: augmented tile development using multi-material (multi-extruder) printers.
  • ATMOS-SIM: a spatial layer of ATMOStiles embedded in a virtual world, creating an immersive network of ATMOStags.
