Regarding the preparations of the fourth (final) demonstrator, these two months, mainly the focus was to handle the scanning of the steel frame (which is going to be the workspace in the demonstrator), finding the right orientation of the gripper regarding the inclination on the workspace and the cutting tasks separately. All these tasks were successfully accomplished with small mock up demos, and prepared to be put together in the main (fourth) demonstrator in the following weeks. In addition to involving all 3 of the experiment objectives; in this fourth demonstrator, the intention is to use the robotic unit as a digital workbench as if on a construction site.
