Developing Process Models for Semi-Autonomous Construction Robot Assessment

Advances in robotics represent a potential shift in design and construction. Since construction planning is based on craft work, the transition to robotic-based construction requires tasks to be defined in much greater detail. In this paper, we begin to develop a standard rule-based process model of robot-influenced operation for mobile robotic platforms with attached robotic arms for performing field construction tasks. The paper focuses on the process model framework and requirements development to support future analysis and standardization efforts. The initial process is drafted for commercially available case study robots. The results present robot-related input, process, and output information from the literature to specify robotic construction processes and operator tasks. An initial analysis of the robotic process model was conducted to consider a generic robot process for specific tasks involving robotic mobilization, implementation, and demobilization. The paper highlights the necessity for the robot to possess independent capability and use BIM information to complete the required construction tasks successfully, thus laying the information foundation for the creation of a generic robotic process model. The process model contributes through the ability to quickly assess new robotic operations and unique requirements for construction planning or means and methods assessment of future robotic uses.
