Abstract

This paper describes the development of two new types of pectoral fins made of elastic materials. The fins were designed to have flexibility and multifunctionality for use not only as propulsive devices in biomimetic underwater vehicles but in other applications such as grippers, thus avoiding the environmental damage often caused by rigid fins. We developed an actively controlled pneumatic fin and a passively controlled flexible fin. The former is composed of silicone with a build-in FMA (flexible micro-actuator) and generates propulsive force by means of a lifting motion driven by the FMA. The latter type of flexible fin is formed of silicone rubber and generates propulsive force by means of a dragging motion. We experimentally verified the elastic pectoral fins' ability to generate propulsive force and used FEM to analyze the fins' behavior.
