Design Of A Robotic Cownose Ray, Mark Marzotto
Design Of A Robotic Cownose Ray, Mark Marzotto
Honors Theses
Nature often inspires advances in science and technology and a promising example of this is mimicking locomotion of underwater animals. The main ways in which manmade aquatic vehicles propel themselves are water jets and propellers, which are inconsistent with how underwater animals swim. The cownose ray displays very efficient thrust with low frequency strokes by using a combination of oscillations and undulations with its pectoral fins. The goal of this paper is to mechanically replicate the actual fin motion of the cownose ray in order to capture these attractive features. The design will account for both the oscillations by designing …

Originating from QL+'s customer requirements, the main technical specifications were to have 80% physiological range of motion, elastic energy return, impact absorption, and no external power sources. Based on the background research conducted and the discussions with experts in the field, the project team decided to focus on designing a prosthetic that focused on plantarflexion and dorsiflexion for a more comfortable gait. The main components of the final design are a hydraulic shock absorber, cam, torsion springs, heel, stopper, and separated keel. The heel, front and back keels, and stopper were manufactured out of carbon fiber. The link, lever, attachment …
