summary Collaborative Robots, or Cobots, bring new possibilities for human-machine interaction within the fabrication process, allowing each actor to contribute with their specific capabilities. However creative interaction brings unexpected changes, obstacles, complexities and non-linearities which are encountered in real time and cannot be predicted in advance. This paper presents an experimental methodology for robotic path planning using Machine Learning. The focus of this methodology is obstacle avoidance. A neural network is deployed, providing a relationship between the robot's pose and its surroundings, thus allowing for motion planning and obstacle avoidance, directly integrated within the design environment. The method is demonstrated through a series of case-studies. The method combines haptic teaching with machine learning to create a task specific dataset, giving the robot the ability to adapt to obstacles without being explicitly programmed at every instruction. This opens the door to shifting to robotic applications for construction in unstructured environments, where adapting to the singularities of the workspace, its occupants and activities presents an important computational hurdle today.

title Use of Virtual Reality in Participatory Design
doi https://doi.org/10.52842/conf.ecaade.2019.2.449

summary Virtual Reality technology was used as a visualization tool in a participatory design process of an urban design project in Santiago, Chile. Community members with little or no familiarity with digital technologies visualized the project using traditional means of architectural representation and immersive virtual reality, and then, answered standardized questionnaires on spatial comprehension. Participants who visualized the project using virtual reality showed a higher level of spatial comprehension and a more precise understanding of the formal and spatial qualities of the project than users who used traditional means.
