A robotic workshop aimed to try a new digital method to construct with unused material, thin wood and remaining material. The goal was to involve the precision and speed of robot arms to scan and transform the hole data into a normalized-able to be used material. A workshop organized by Yuko Ishizu (Orange Gellies) and Achilleas Xydis (ETH Zurich).

The available wood varied from unused branchs of cedars and cypress of a diameter from 9 to 18 cm. Since there were also different diameters and bends at each end, it was necessary to grasp the best approximate shape in order to know the core of the material. Thanks to the robot scanning tool, we could collect the coordinates at each position and therefore generate the timber model in Grasshopper/Kuka PRC and then be able to create the robot path.

Because the timber branchs have different diameters at each extremety, it was necessary to parametrically design a joints that would adjust their lenght so the chainsaw could cut it correctly.

As part of our experimentation through Robot arm, we conducted few tests to change the physical properties of wood by Kerf Bending. By changing the depth and width of the incision, flexibility was implemented and tested on a hard material.
