Craft vision and goals l.jpg
CRAFT - Vision and Goals

To develop the science and engineering needed for rapid automated fabrication of structures of various scales, up to very large objects such as buildings.

The goal is a major breakthrough in Mega-Scale fabrication.

Viterbi School of Engineering .


Grand challenge l.jpg
Grand Challenge

  • Building a custom-designed house in a day while radically reducing the costs, injuries, waste and environmental impact associated with traditional construction techniques.

    • affordable housing for the 30 million U.S. households facing cost burdens or overcrowding;

    • emergency housing for the 37 million/year victims of natural (and/or man-made) disasters;

    • new styles of housing based on curved rather than straight surfaces;

    • extraterrestrial buildings constructed from in situ materials;

  • With national construction-related expenditures currently totaling close to $1 trillion annually, the potential impact is enormous.

  • The goal: a revolution in housing construction

Extrudable materials fabrication l.jpg
Extrudable materials & fabrication

  • Perform underlying basic research necessary to develop the materials and structures for automated mega-scale fabrication

  • Integrate materials into ultra-efficient structures

  • Integrate materials with delivery systems and robots from other thrusts

Viterbi School of Engineering .


Robotics fab modular components assembly l.jpg
Robotics fab, modular components & assembly

  • Perform research and develop various mono and distributed robots, tools, software and their integration into systems for assembling modules in situ to form functional attributes of structures

  • Robots’ locations, movements and working areas are dynamically changing along with environment. Develop a mathematical / geometric model of environment and a robot coordination protocol.

  • Perform the fundamental research in the modules to be placed internal to the extruded material that transform an extrusion into a functional wall or roof of a mega-scale structure. The modules that make a post-modern interactive structure include:

    • normal reinforcing, plumbing, and electricity conduits

    • Integrated communication, interactive sensing and displays

  • Integrate the Modules and Assembly Thrust with Extruded Materials and Software
