Solution Overview
Problem
Current construction robots are insufficiently developed for maintaining and repairing structures, particularly those that have aged or were poorly designed, due to a lack of focus on maintenance robots in construction sites.
Innovation Solution
A robot equipped with a vision module for measuring luminance and depth, a control module for identifying protruding, depressed, and cracked areas, a chipping module for removal, and an injection module for filling, along with a sealing module for cracked areas, allowing for efficient maintenance and repair of structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If construction robots are developed for building operations, then construction efficiency is improved, but maintenance capability is insufficient
Solution Approach 1:
The robot is designed with multi-functional capabilities, integrating both building operations and maintenance functions into a single system. The robot can perform various maintenance tasks including protrusion removal, depression filling, and crack sealing using different modules (chipping module, injection module, sealing module), thereby achieving versatility in construction site operations.
2Reliability
If manual maintenance operations are performed, then maintenance quality is maintained, but labor shortages and skilled worker reductions cause inefficiency
Solution Approach 1:
The robot performs autonomous maintenance operations by automatically detecting structure defects through vision modules, analyzing images to identify protrusions, depressions, and cracks, and executing repair operations without human intervention. The control module coordinates various modules to complete maintenance tasks independently, reducing dependency on skilled workers while maintaining maintenance quality.
3Adaptability or versatility
If comprehensive maintenance functions are added to robots, then maintenance coverage is improved, but device complexity increases
Solution Approach 1:
The robot system is divided into distinct functional modules: vision module for defect detection, control module for decision-making, chipping module for protrusion removal, injection module for depression filling, and sealing module for crack repair. Each module performs a specific function and can operate independently, making the complex maintenance capability manageable through modular architecture.

AI summary
Provided are a robot for managing a structure, and a method of controlling the robot. The robot for maintaining and repairing the structure measures a luminance value by capturing an image of the structure, or measures depth information of the structure by using a laser sensor or stereo vision, determines a protruding portion or depressed portion of the structure by using the measured luminance value or the measured depth information. Also, the robot removes the determined protruding portion and fills the determined depressed portion by using a combination hardener. Accordingly, protrusion, depression, and crack of a wall caused by deterioration or poor construction of the structure may be automatically found and repaired so as to efficiently manage the structure.
