Comparison of dusty robotics and traditional layout methods

Abstract

Abstract The use of robots in construction has been rising in recent years. However, limited knowledge is available to understand how robots perform compared to existing processes. Therefore, this research compares the performance of manual layout to Dusty Robotics’ layout robot, an autonomous robot that marks the location of structures to be built and fixtures to be installed on a construction site. Using a Robot Evaluation Framework, we evaluate safety, quality, cost, and schedule performance metrics on drywall, mechanical, plumbing, and electrical layout in an 8-floor medical office building in Los Angeles as a case study. Dusty significantly outperformed manual layout methods across these parameters, resulting in a 68% reduction in total labor hours, an 18% decrease in total days spent performing layout, and a 99% reduction of physically straining work. Accuracy was enhanced by 50%, and design conflicts were identified earlier during the robotic layout process compared to the traditional process. Rework was reduced from 6.42% to 0.25%, a 96% reduction. The research findings suggest avenues to maximize the benefits of robotic layout, such as introducing the robot earlier in the project lifecycle during pre-construction and deploying multiple robots simultaneously. Layout robots present a promising technology for construction contractors to deploy on jobsites to improve project outcomes.
