Design of Robot based Work Progress Monitoring System for the Building Construction Site

摘要

The building construction project has plan, budget and timeline and the construction work should be done according to the work schedule predefined during the design period. But many construction projects are delayed due to the human work error and this leads to the over budget. To reduce the delay of construction work, the work progress should be monitored periodically and the delayed part should be managed early and fast. For this purpose, the construction industry usually sends the project manager to the construction site with clipboards and camera. However checking the progress by human can cause error and have limitation. To reduce the error and automate the progress monitoring we propose the robot based work progress monitoring system for the building construction site. We combine the drone with propellers and usual robot with wheels. The propeller is used to avoid the obstacle or floor change and the wheel is used to go around on the flat area. The monitoring robot has the VR camera for the video recoding and the LiDAR for the laser scanning. The route for the robot is generated based on the timeline and 3D design data such as 3D CAD or BIM. Progress monitoring is done based on the comparison between the design data and collected data by the robot.
