The fluidic muscle from Festo, in combination with the Fin Ray Effect®, constitutes Aqua_rays central propulsion and control unit. The Fin Ray Effect® is a construction that is derived from the functional anatomy of a fishs fin and imitates almost perfectly the mode of propulsion executed by the natural model. It is entirely due to the mechanics of the fin rays-bony rods that constitute the fins supporting structure that the wing can be arched to ensure even distribution of forces; this makes for a highly efficient drive mechanism.
