Rays are fascinating sea creatures. Experts consider them to have perfected underwater flight and gliding. As they swim, they beat their fins in the water like a bird beats its wings in the air. Their wave-shaped movements form an optimum combination of maximum propulsion with minimum energy consumption. The flow-optimised shape allows the manta ray to move particularly elegantly and makes it a real underwater acrobat.

Fluidic muscle and Fin Ray Effect® combined

We use the fluidic muscle for the central propulsion and control unit of the Aqua_ray. Two pairs of muscles working in opposite directions, combined with Fin Ray Effect®, form 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.
