The paper parents our recent development on the earthworm-like soft robot. The robot is designed through combination of smart electro-active polymer (EAP) materials and the efficient expandable structure. The employed EAP material, called ionic polymer-metal composite (IPMC) that can directly provide the actuation to the expendable scissor-lift structure, so as to enable the robot to mimic locomotion...
Electromagnetic actuators are versatile and able to meet demanding requirements, such as operation in very low or very high temperatures. When the actuator is used in a high-temperature environment, we need to know how the force-producing capability of the actuator is influenced by the operating temperature. Previous research works [1-2] fail to show the dependence of the actuator force on the temperature.
Emerging bioinspired underwater systems, such as autonomous ocean mapping and surveillance vehicles, that maneuver through their environment by mimicking the swimming motion of aquatic animals, can benefit from soft monolithic actuators and control surfaces capable of undergoing complex deformations. Herein, an electrically driven ionic polymer–metal composite (IPMC) artificial muscle with uniquely...
In this work, we explore a promising electroactive polymer (EAP), called ionic polymer-metal composite (IPMC) as a material to use as a multi degree of freedom actuator. Configuration of our interest is a cylindrical IPMC with 2-DOF electromechanical actuation capability. The desired functionality was achieved by fabricating unique inter-digitated electrodes. Firstly, a 3D finite element (FE) model...
