Cyber-Physical Construction Platform

Research Project 8-1 (RP 8-1)


The aim of this research project is to develop a cyber-physical construction (CPC) platform for the automated and rope guided handling of heavy loads and the on-site assembly of prefabricated elements for multi-storey buildings. An automated tower crane, as a large workspace serving the handling system, realises the pick-up and transportation processes. Imaging methods or laser scanning is used to monitor all automated processes and the overall construction progress resulting in a construction site monitoring concept. With the aim of 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 to be automated will be derived from the 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.

We will develop a novel hook-mounted gripper system for the tower crane, to handle differently shaped elements. In addition, we aim to automatically perform coordinated motions of the tower crane and the spider crane, which is the subject of the research project Robotic Platform for Cyber-Physical Assembly (RP 16-1), in order to seamlessly place prefabricated elements. This will be achieved by developing hybrid control strategies.
