Would love it if you'd check out YouTube where, with a SONIA demo in the background at JavaOne 2007, yours truly talks with David Mercier, an engineering student at Ecole de Technologie Supérieure (ETS) in Montreal, Quebec, Canada. David is technical lead of a team of more than 20 volunteer engineering students that created SONIA, a Java-powered autonomous underwater vehicle (AUV) that can autonomously pass through a gate, detect a flashing light, find and connect with a docking station, locate a pipe and drop material into a bin — all underwater and with no communication with the team. David's team has successfully demonstrated the power, versatility, and portability of Java technology by building AUVs that continuously rank among the top three in the world. Have a look and let me know what you think. Thanks!
