Inspired by the manta ray
Whether by means of dynamically beating wings or elegant gliding: the Aqua_ray uses its functional anatomy to manoeuvre through the water in an easy and energy-efficient manner. The artificial fish is not only based on the real manta ray in terms of its shape, however. Its motion pattern closely approximates its natural model.
Fluidic Muscle and Fin Ray Effect® combined
For the central propulsion and control unit for the Aqua_ray, Festo uses the Fluidic Muscle: two pairs of muscles working in opposite directions, combined with the Fin Ray Effect®, for the beating wing drive in the two wings. The structure with Fin Ray Effect® is a design derived from the functional anatomy of a fish fin. It enables the fin drive of its natural role model to be imitated almost perfectly.
