Construction Robot End Effector Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction robots struggle to efficiently install supports and adjust their height simultaneously in double floor construction, due to the need for manual adjustments and repeated processes.
Innovation Solution
A construction robot equipped with a manipulator, an end effector with a holding unit and a height adjusting unit, a recognizing unit, and a measuring unit, allowing for simultaneous installation and height adjustment of supports by recognizing positions and measuring positional relations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a construction robot is used to install supports, then installation efficiency is improved, but the ability to simultaneously adjust height based on floor unevenness deteriorates
Solution Approach 1:
The patent combines the support installation function and height adjustment function into a single integrated end effector. The height adjusting unit is merged with the holding unit, allowing the robot to perform both installation and height adjustment in one operation, thereby resolving the contradiction between installation efficiency and height adaptability
Solution Approach 2:
The end effector is designed with multi-functionality, serving both as a holding unit for gripping the support and as a height adjusting unit. This universal design enables the robot to adapt to different height requirements while maintaining high installation efficiency, addressing the contradiction between productivity and adaptability
2Manufacturing precision
If manual height adjustment is performed, then height precision is improved, but installation time increases
Solution Approach 1:
The patent replaces manual mechanical height adjustment with an automated height adjusting unit that includes a motor-driven screw mechanism. This substitution maintains precise height control while eliminating the time-consuming manual adjustment process, resolving the contradiction between height precision and installation time
Solution Approach 2:
The height adjusting unit is designed to perform height adjustment automatically during the installation process itself, rather than as a separate subsequent step. This preliminary action approach ensures precise height positioning is achieved simultaneously with support installation, eliminating wasted time
3Quantity of substance
If repeated transport and installation processes are performed, then complete coverage is improved, but total installation time increases
Solution Approach 1:
The patent enables continuous installation operation by eliminating the need to stop for height adjustments between supports. The automated height adjusting unit allows the robot to maintain continuous motion and perform installation and adjustment in one uninterrupted action, thereby reducing total installation time while installing the required quantity of supports

AI summary
A construction robot for mounting a member with a changeable height on a body at a predetermined height includes: a manipulator; an end effector provided at a distal end of the manipulator; a recognizing unit configured to recognize positions of the member and the body; and a measuring unit configured to measure a positional relation between the member and the body. The end effector includes a holding unit configured to hold the member in a releasable manner, and a height adjusting unit configured to adjust a height of the member by moving the member in contact with the body in a direction moving closer to or in a direction moving away from the body.
