Robot system for automated tiling on prefabricated construction elements: mechanical concept, positioning strategies based on neural networks

摘要

To reduce the cycle time and to take account of the rising quality requirements, the laying of tiles in prefabrication was automated. In order to meet the existing quality requirements, a special positioning strategy and a laying procedure for tiles was developed at the Fraunhofer IPA and implemented in an automated pilot cell. The positioning strategy based on neural networks enables individual arrangement, taking account the deviation of the individual tiles, to fulfil the prefabrication optical quality criteria. The laying procedure enables the automatic laying of tiles using the optimum laying parameters for each case. Practical tests with the pilot cell demonstrated that the positioning strategy and laying procedure could be implemented.
