ECE4006A: Senior Design

A Candidate Project

Sonar Pinger

Georgia Tech's student Marine Robotics Group (MRG) participates in an annual Navy competition to construct and demonstrate a submarine no larger than 3'x3'x6' which can navigate, detect obstacles, and surface over a sonar pinger in the San Diego Naval Base's Navy Seal training pool. These students need a sonar pinger which emits pulses at frequencies between 20 and 30 kHz as described in the competition rules found linked at the MRG's URL. This device would probably fit inside a short length of PVC pipe and include a battery, piezoelectric transducer, waterproof user interface (probably magnetic switches), and drive electronics to run the pinger for at least the competitions duration during testing in Atlanta. Dr. Whit Smith is the MRG's ECE faculty contact. Send email for additional details.
