Underwater swimmers present unique opportunities for using bodily reconfiguration self propulsion. Origami-inspired designs are low-cost, fast to fabricate, robust, and can be used create compliant mechanisms useful in energy efficient underwater locomotion. In this paper, we demonstrate an origami-inspired robot that change its body shape ingest expel water, creating a jet propels it forward s...

A propulsion system based on acoustic streaming generated by Helmholtz resonators is presented. High frequency (>60 kHz) electrostatically driven micromachined Helmholtz resonators constitute the basic unit of the system. Microjets produced at the exit of these resonators can be combined to form a distributed propulsion system. A high yield (>85%) fabrication process is introduced for fabricati...

Cnidarian medusae, commonly known as jellyfish, represent the earliest known animal taxa to achieve locomotion using muscle power. Propulsion by medusae requires the force of bell contraction to generate forward thrust. However, thrust production is limited in medusae by the primitive structure of their epitheliomuscular cells. This paper demonstrates that constraints in available locomotor mus...

A web-based workflow system was developed at the Jet Propulsion Laboratory and several pilot applications were developed. We give an overview of the architecture and functionality of the workflow system, describe three pilot workflows that have been or are being deployed, and relate lessons learned.
