The Ripariasome is used for infiltration via low current water systems. It has a watertight capsule that can carry small objects: hard drives, messages, combustibles, evidence.
Specs: Polymer skeleton with flexible undulating joints is covered by a camouflaged rubber skin. The skin is joined on the top by an interlocking seal which can be unzipped for access to the skeleton and interior capsule. The underbelly is ridged providing grip on stream beds. Motor is mostly muffled when underwater, but can be heard from several yards off when in open air, or when working against a swift current. Navigates by a GPS or self-navigation system with general directional coordinates.
