AI Technical Summary

Technical Problem

The traditional method of manually forming lines for construction contractors using colored chalk and string on construction sites is limited in representing useful information and often leads to confusion due to the limited number of distinguishable colors and the time-consuming nature of handwritten signs, especially in dusty environments.

Method used

A mobile printing robot system that prints contractor information on a building surface using a mobile robot, encoding line type attribute information with alphanumeric characters, direction, and offset information directly onto architectural design drawings during a single pass, assisting construction workers with precise line markings.

Benefits of technology

Enhances clarity and efficiency by providing precise and automated line markings with additional information, reducing confusion and time spent interpreting CAD drawings, and ensuring accurate construction by integrating line type attributes, direction, and offset adjustments.

Abstract

The mobile printing robot prints architectural blueprints onto a construction surface. The architectural blueprints have lines printed on them. The mobile printing robot also prints additional line attribute information to assist construction workers. This can include a description of the line type (e.g., control line, wall type, etc.). As another example, it can also include information about offsets. As yet another example, directional information can be printed for the lines. As yet another example, required or optional construction details can be printed, such as materials to be used to implement features associated with the blueprint lines.
