Cyber-Physical Construction Platform

Research Project 8 (RP 8)

CYBER-PHYSICAL CONSTRUCTION PLATFORM

This research project addresses the development of a cyber-physical construction (CPC) platform for automated and rope guided handling of heavy loads and on-site assembly of prefabricated elements for multi-storey buildings. An automated tower crane realizes pick up and transportation processes as a large workspace serving handling system. Imaging methods or laser scanning will be applied to monitor all automated processes and the overall construction progress resulting in a construction site monitoring concept. Aiming at full automation, we will plan paths and trajectories for material transportation and assembly based on an environmental model derived from these sensors. The specific tasks that shall be executed automatically will be derived from planning data of the construction process. To be able to compare the current state of the site with the planning data, a semantic interpretation will be added to the geometric information of the as-built 3D model.

In order to handle different shaped elements, we will develop a novel hook-mounted gripper system for the tower crane. Additionally, we aim at the automatic execution of coordinated motions of the tower crane and the spider crane covered by Research Project 16 in order to seamlessly place prefabricated elements. This is achieved through the development of hybrid control strategies.
