The development of building blocks, and standard interconnects in particular, enables promising perspectives for the assembly of large structures on-orbit. By coupling these standard interconnects with
dexterous arms, it is now possible to imagine orbital robots assembling, in-situ, modular structures to emancipate from launcher constraints.
Such a mission scenario and related concept of operations are proposed within the ESA MIRROR project. It involves a modular multi-arm installation
robot to address this challenge. This paper deals with the design of a fully representative breadboard for this innovative robot in order to prove its concept and abilities. This demonstrator features a ground
equivalent robotic system, a testbed and necessary ground support equipments
