An underwater robotic vehicle development system for building underwater robotic vehicles (URVs), including a pressure vessel system, modular chassis elements, a propulsion system and compatible buoyancy modules. The pressure vessel system uses standardized, interchangeable modules to allow for ease of modification of the URV and accommodation of different internal and external components such as sensors and computer systems. The system also includes standard, reconfigurable connections of the pressure vessel to the modular chassis system. A standardized, modular propulsion system includes a magnetic clutch, and a magnetic sleeve used to power the URV on or off.
