Modular Cargo Ship

This ship is completly modular.  Propulsion, cockpit, cargo storage modules, communications all attach to a frame.  That frame can be adjusted according to the mission and the volume of cargo to transport.

The proposed cockpit has a robotic arm which allows it to move modules and configure the vessel.

The only limit is the immagination!  New modules can be created to add functionality (ex. habitation module for longuer missions), larger ships built by expanding the frame, etc.  The control is yours!

The last image shows a fully loaded cargo ship, using existing modules.  It is not part of the contest submission (greater number of parts), simply showing possibilities.
