Design and integration of a modular architecture for a versatile, reconfigurable and re-adaptable space vehicle is presented with application to a small rover. To gain modularity, both at system and subsystem level, attention has been paid to the selection of interfaces and of an adequate data and power bus. A modular system, based on CAN and SpaceWire data communication bus, has been designed and a first level of distributed intelligence has been achieved using PIC micro-controllers in each subsystem. The modules have been designed with the same mechanical interface to obtain a 2D repetitive pattern. In order to test this architecture aboard a rover, some basic sub-systems, such as the power control unit, the battery control unit, the engine control unit and a PC104-based computer have been integrated and preliminarily tested.
