Architectural robotics includes the design, integration, and implementation of programmable machines in manufacturing processes and/or in operational responsive systems. This workshop focused on the first set of applications referring to methods of production that employ numerically controlled fabrication routines for architectural implementations.

 

This workshop intended to provide an introduction and overview to architectural robotics as a creative inter-disciplinary emerging realm. The manifestation of this research and process was designed computation methods and prototypes focusing on stairs as fundamental and dynamic architectural elements, which was exhibited once during and once at the end of the workshop. During the studio, Scalalogy (the science of stairs) was a reference as a comprehensive branch of architectural science that dealt with the interdependence of humans and stairs.

 

A fundamental element of architecture and an essential tool of ascent, stairs have captured the imagination of architects throughout time and challenged them to exercise their creativity and skill in making and reinventing them repeatedly. In addition to their interdependence with humans from a practical point of view, stairs appear in arts, literature, and movies as wonderful and whimsical constructs. Moreover, from a computational design point of view, stairs are nested for-loops with which one may explore complex and performative configurations. This complexity can be understood as multi-scalar architectural heterogeneous patterns integrating structure, function and aesthetics.

 

In the 19th century, French architects used to produce scale models of staircases they had built. The models were extremely detailed and were used similarly to a modern-day portfolio allowing the architects to carry them around and showcasing their skills and craft to attract future clients.

 

Reviving this historical reference, and noting the inherent parametric nature of stairs, students built 1:1 staircase prototypes. The materialization was a fusion of robotic fabrication techniques as well as human craft and detailing with the results exhibited in Platform 28 and PATTERNITECTURE event at Niavaran Artistic Creations Foundation (NACF).

 

Robotic Light Printing

As the first exercise with the robot, light printing was used as the medium to illustrate tool path, and translate digital lines to movement. A point light source was used as the end effector and the robot’s movement was mapped with long exposure photographs.

 

Twisted Ribbon

Stairs represent one of the oldest and most intricate design problems in architecture. Aesthetics, circulation, structure, and safety combine to create a complex network of factors. Despite the essentially parametric nature of stairs, this project aims to adopt and apply creative inter-disciplinary methods of design and fabrication such as utilizing HWC (hot wire cutting) system with a robot arm. The objective of the project has been to design a parametric stair and fabricate it with an ABB robot arm. The design process starts with two twisted curves, combined with thickness variation for steps and handrail. Moreover, Power lines of the twisted surfaces intertwine and form tessellation patterns, which cover top and underside of the stair surfaces.

Bezier Stair

Stair is typically an element to connect different levels and to facilitate vertical circulation. However, in “Platform 28” it cannot be defined in its general format as there is no other level. Therefore, it is considered as an exhibited object, a piece of art that is going to be “watched” not

used. A “Bezier” graph initiates the formation of the stair. From a geometrical point of view, a Bezier curve always passes through the first and last control points and lies between the convex hull of the control points. The control points of the Bezier alter parametrically, thus the nucleus curves are created.

Casting/ Coating

Parallel to design to robotic production of two main stair projects, we had series of casting and coating tests and prototyping with gypsum and fibreglass.
