    3. 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 .

    4. 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 Viterbi School of Engineering .

Architectural Design Logistics plan Robot Integrated Modular Commands Nozzle path plan CC Software Components Hardware Assembly plans Systems Hardware & Assembly Inspection plan Feedback Visual Data Sensory Data Supply Dispatch Indexed Video Log Performance Restrictions Extrudable Structure design & Materials & Predictive Performance performance Requirements Fabrication Interrelationships among the three research thrusts Viterbi School of Engineering .

    9. 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 .

    10. 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 Viterbi School of Engineering .
