چکیده

This paper describes an electroactive polymer robot with ray-like pectoral fins. Electroactive polymers are materials that change their geometry in response to electric field and can be used to replace electromechanical devices. The aim of this study is to show that these materials can be used to build more complicated devices and the behaviour of these devices can be coordinated to some extent. Both of the pectoral fins are built of eight electroactive polymer muscles. The experiments show that the fins are able to generate undulating motion and propel the body forward. The speed of the device is considerably slower than that of ray-like fishes but the device also has a smaller muscle mass and total mass ratio compared to aquatic animals.

Towards a biomimetic EAP robot

This paper describes preliminary experiments with an EAP (electroactive polymer) robot. The research reported here serves two purposes. First, we aim at building a testbed to investigate control methods of EAP actuators. Second, we wish to build an underwater robot that mimics undulating motions of pectoral fins. The prototype described in this paper has two pectoral fins. The tests confirm tha...

Bio-inspired Underwater Robots Powered by Electroactive Polymer Artificial Muscles

Autonomous under robots are highly demanded in environmental monitoring, intelligent collection, and deep water exploration. Aquatic animals (e.g., fishes, whales, rays, etc.) are ultimate examples of superior swimmers as a result of millions of years of evolution, endowed with a variety of morphological and structural features for moving through water with speed, agility, and efficiency. Recen...

A review on robotic fish enabled by ionic polymer–metal composite artificial muscles

A novel actuating material, which is lightweight, soft, and capable of generating large flapping motion under electrical stimuli, is highly desirable to build energy-efficient and maneuverable bio-inspired underwater robots. Ionic polymer-metal composites are important category of electroactive polymers, since they can generate large bending motions under low actuation voltages. IPMCs are ideal...

Bio-inspired Robotic Cownose Ray Propelled by Electroactive Polymer Pectoral Fin

The cownose ray (Rhinoptera bonasus) demonstrates excellent swimming capabilities; generating highly efficient thrust via flapping of dorsally flattened pectoral fins. In this paper, we present a bio-inspired and free swimming robot that mimics the swimming behavior of the cownose ray. The robot has two artificial pectoral fins to generate thrust through a twisted flapping motion. Each artifici...

Magnetic fish-robot based on multi-motion control of a flexible magnetic actuator.

This paper presents a biologically inspired fish-robot driven by a single flexible magnetic actuator with a rotating magnetic field in a three-axis Helmholtz coil. Generally, magnetic fish-robots are powered by alternating and gradient magnetic fields, which provide a single motion such as bending the fish-robot's fins. On the other hand, a flexible magnetic actuator driven by an external rotat...
