This Dataverse contains the software, hardware design resources, and experimental data developed for a multi-robot construction system for the automated on-site adhesive bonding of prefabricated cross-laminated timber (CLT) floor panels. The system combines a digitally controlled tower crane with compact robots temporarily embedded within the panels to support vision-guided assembly, apply a two-component structural adhesive, and generate the pressing force required to close and cure the bonded joints. The included datasets provide: (i) the control and coordination software for crane-assisted panel placement, synchronized adhesive application, and joint pressing; (ii) the mechanical design, fabrication files, and parts documentation for the adhesive robot; and (iii) calibration, application, pressing, and bond-line evaluation data generated during the robot’s development and experimental validation.
