Construction Automation
GSD 6415, Spring 2009

Prerequisites: CAD/CAM 1 or permission of instructor

This advanced seminar introduces students to emerging technologies under the broad umbrella of construction automation. An extension of research on computer-aided design and manufacturing techniques, the seminar introduces the principles of robotics and automated systems in the context of architectural construction, with reference to product design and other industries. Lecture topics include a historic overview as well as an introduction to different types of robotic systems, automation systems and their elements. Techniques and strategies for programming industrial robots will be introduced, with an emphasis on the use of offline simulation and programming environments with graphical user interfaces. Distinctions between numerically-controlled machines and robotic systems will be made throughout.

Based on lectures that introduce the fundamental principles students research case studies of applications and advanced technologies in the first half of the course. The second half of the course is dedicated to developing and conducting immersion experiments with actual industrial robots and their associated programming/teaching environment. Experimental work explores 'design for robotics' both for on-site as well as off-site applications. Speculative and creative use of robotic material handling and fabrication approaches is encouraged. How is design and construction impacted by the introduction of automated, robotic systems? Project work can range from problem-solving to highly speculative in nature, and can emphasize any combination of digital as well as physical aspects.

In addition to lectures and hands-on workshops there are several guest lectures and field trips to visit local companies and researchers involved in commercial as well as speculative work in robotics.

Mobile Information Unit
GSD 9206A, Spring 2006

Students in the fall 2006 course CAD/CAM I have proposed the design for a mobile information unit that is to be built in 2007. The unit will disseminate information about events at Harvard and its Art Museums to residents of Cambridge, Allston and Somerville, as well as to the Harvard community. As a mobile, trailer-mounted unit it can be relocated to various sites.

This seminar starts with the design proposal by the winning group of students. The concept needs to be developed into a robust, rugged system that stands up to exterior conditions while preserving its interactive design qualities. The seminar deals with the design development, preparation of fabrication and prototyping of the unit. Aspects that need further study include material choices, fabrication methods, and various technical issues that relate to the need for an integrated interactive information display system. The question of power supply, for example, needs closer study, possibly involving photovoltaics. Contacts with suppliers and fabricators need to be established. As there is a limited budget cost estimates and cost tracking are essential. Many other technical and process issues are addressed.

Activities in the seminar involve research, simulations, physical prototyping and fabrication. The group meets weekly, but independent work is essential between the meetings. The enrollment is limited to 12 students. The number of students admitted through the lottery is going to be smaller, and is announced during the course presentation.
