P14251: Acoustic Underwater Communications

Project Summary

Beginning this year, Boeing and RIT will begin the production of an unmanned underwater robot. One of the key subsystems of this robot will be a limited bandwidth communication system. This subsystem will be designed by RIT to provide underwater acoustic communication for the robot. In future years, it will be combined with several other subsystems to form a fully functioning robot.

Requirements include being able to communicate at a minimum range of 30 meters and be able to withstand environmental conditions as well as pressures of 10 meters of water. A communication rate of at least 10kbps must be obtained while consuming the lowest amount of power possible. The system must be easy to implement, easy to maintain, and robust. If time allows, data encryption and compression functionality will be added.

In addition to creating the communication system, a basis will be provided for future expansions upon the communications module. Ultimately this project will showcase RIT’s technological and production capabilities and lay the groundwork for future Boeing & RIT collaborations.

Constraints

Our constraints are the following:

We must use an acoustic communications scheme.

We have a maximum power consumption of 15 Watts.

Our total project budget is $1750.

Project Goals and Key Deliverables

Upon the completion of MSD II, our team will have delivered two communication modules each consisting of a waterproof housing, a speaker and hydrophone, processing circuitry, micro-controller, and user-end and micro-controller programming.
