Paper Abstract

We present a stackable configuration of loudspeaker-type artificial muscle module. These modules are antagonisticallycoupled to enhance the delivery of blocking force and speed of deformation. We analyze a cycle of antagonisticallycouple configuration by theory, and maximize the cycle of the antagonistically-coupled loudspeaker configuration using a semi-empirical method. We realize an output force of about 4N for a single layer, and up to 15N for three stacked layers. The corresponding displacement at maximum actuation is about 10mm. We further introduce a control circuit to enhance output mechanical power of the cycle. This work serves to rationalize the analysis, design and construction of soft actuator systems capable of delivering high mechanical power output within a small space.
