In this paper, the Cosmo modules [16] developed within the
EU Symbrion/Replicator projects [8], are utilized. Each module
is equipped with basic sensors (camera, IR distance sensor,
accelerometers), a Blackfin processor, two screw-drives for 2D
locomotion and the main hinge for 3D locomotion. Power is provided
by an internal battery or can be shared within the organism
through a power bus. The modules can communicate via the Zig-
Bee interface and, if connected, also using Ethernet. The modules
are depicted in Fig. 1.
