During this 4 days workshop, students from the Fabrication Ecologies research line of the Master in Advanced Architecture 2013 were able to develop and test a new fabrication protocol deploying Hemp fibres by means of an industrial robot.
Through the production of a 1:1 scale prototype, the 4 teams explored the design opportunities arising from 2 different fabrication techniques developed within the Fabrication Ecologies Studio, focussed on the production of:
- an aggregate substratum via pick and place of fibrous component units.
- a non-woven fabric skin via robotic spraying of row hemp filaments.

The collaborative effort progressed in loops, with the work of one group informing the operations of the next. The feedback was mediated by a set of interfaces for real-time scanning (Kinect) and digital generative modelling (Grasshopper). The fabrication process than evolved into a conversation between designer, machine, material system, designer, prototype, machine, designer, and so on; each loop driven by a set of negotiations and specific design decisions.

Such fabrication protocol opens the possibility for a new form of participatory mass-customisation, ones that operates in real-time during and takes into account multiple factors such as design intentions, material behaviour, mechanical constraints and microclimatic conditions.

Our first experimental set up was the following:

-The robot was controlled by each student via Grasshopper, through the use of the KUKA | Krc plug-in (from association for robots in architecture) for Grasshopper and Rhino. Each group did draw a series of parametric lines that would become the tool paths for the robot.

-A video simulation with the virtual robot in Grasshopper was performed by each student to understand the behaviour of the machine along the path and amend eventual errors; the video  would allow also the testing of multiple path parameters and robot behavioural options.

-The tool mounted on the robot contained 1 fixed LED light and 2 or 4 blinking ones; the blinking was also controlled via Grasshopper and related to the robotic arm path.

-A camera was positioned in front of the robot and its exposure tuned to the particular lighting conditions and the length in time of the tool path. Such configuration allowed capturing the ephemeral lighting traces left by the robotic arm movements. The robotic behaviour is therefore translated into a 3D robotic light painting.
