This is a proceedings of 21 papers presented at the 2015 Conference on Autonomous and Robotic Construction of Infrastructure at Iowa State University, Ames, Iowa, on June 2–3, 2015. The conference provided information on how autonomous robotics systems are being applied in practice, discussed emerging technologies, and described theories that will no doubt shape the future of this field. The papers cover a range of topics including mobile robotic operations, visual analysis, terrain modeling, simulations inspired by natural processes, multi-dimensional modeling, 3D printing, sensors, data processing, and new applications for construction technologies like photogrammetry. An underlying theme for many of the papers is data analytics—trying to make sense of and bring value to the deluge of data now being generated during construction operations (e.g., machine telematics, digital photos, weather data, sensors, etc.).
