This document describes the SHAREWORK system specifications for each use-case, starting from the requirements already identified in D1.1 “Use cases definition, system requirements and KPIs”. Each use case scenario description is improved with greater details on humanrobot collaborative tasks and layouts are presented through 2D and 3D visualization. Furthermore, general module specifications and inter-modules dependencies are reported, also detailing the role of all modules in each use-case. In such a way, a comprehensive and deeper understanding of all SHAREWORK system components emerges from this deliverable, highlighting its main features and differences in implementation in the four use cases.
