An exemplary inventive molding device includes two mold components characterized by matching rounded-star shapes. Each mold component includes eight congruent rounded-tip projections and eight congruent apertured sections separated from each other by the projections and describing a ring shape. The projections correspond to the equiangular points of a star. Each section has a medial hole and is interposed between and connects two projections. The mold components are joined so that their respective projections and holes are even with each other and fasteners are installed through the holes. Appropriate introduction and curing of a castable material inside the joined mold components produces a flexible device suitable for use as part of a biomimicking soft robot.

The invention is directed to a towing adaptation system for optimizing the pitch attitude, hydrodynamic lift and drag forces on an underwater acoustic vessel. The towing adaptation system an underwater vessel to which is attached a first adapter plate and a second adapter plate, with each adapter plate having a plurality of vertically displaced staged attachment points. Corresponding attachment points of the first and second adapter plates form attachment pairs, with each attachment pair calibrated to provide a desired cable angle, hydrodynamic lift, and drag force, at a predetermined steady-state speed, for optimizing performance.
