This video presents the development of a biomimetic propulsion mechanism, inspired by the flexible undulating fins encountered in certain electric eel species (knifefishes, in particular). The prototype is comprised of eight actively-controlled fin rays (driven by R/C servos), which are interconnected by a flexible silicone membrane. Propulsion is obtained by the propagation of a traveling wave along the fin, obtained through appropriately coordinated motions of the rays.
