There is an interesting, techy video on the UC San Diego "Stingray" autonomous vehicle on www.engineeringtv.com The video was shot at the Embedded Systems Conference 2011. Good job Chris Barngrover.
Also, the students themselves have a number of videos of their autonomous underwater vehicle on YouTube and on their IBOTICS site. Also, check out the related Stingray Underwater Craft video from Calit2.
