Abstract/Summary

To design and build an acoustic release and receiver system, our team performed extensive
background research, developed thoughtful concepts of potential designs, performed ideation,
and constructed multiple prototypes. After constructing both a conceptual and structural
prototype, our team began updating the structural prototype to meet requirements expected of the
verification prototype. After completing the verification prototype, our team entered the testing
stage of the project. The electronics housings were pressure tested to determine if any leaks
would occur, the Dyneema rope was tensile tested to verify the system could withstand affected
loads, and the time to re-spool the device was determined. Key specifications like maximum
system weight and size were also measured and recorded. Some tests were not able to be
performed as expected due to lack of a completed acoustic release system provided by our
counterpart Computer Engineering (CPE) team; however, our team feels that this project
accomplished key specifications required of the Mechanical Engineering (ME) team. With
further project development, the final device would allow for easy retrieval and re-deployment,
eliminating the need to take the system onshore, and maximizing the time the system can spend
collecting data.
