VENT 7 - COMMUNICATIONS

Sonar
NPS Phoenix p. 171 Underwater Robots Sends ping and analyzes return structure Controller Language Prolog C used for some things Basically we need a programming language to program our toys Logos is an example, but we may end up making our own language Need a processor (cricket, but the Gespac in the Phoenix is pretty big, but so is it) Tether made of optic fiber links for data and video signals transmission VORTEX p 198 Underwater Robots

Telecommunication
-The LOBSTER! Page 255 Underwater Robots Yeah, but this has been scrapped sigh
-Ultrasonic command link system
-Vision-based communication system using El (Electro-Luminescent) panels
-The Burger I and II With Ultrasonic command link system Robot can communicate 1 byte commands with up to seven other agents Including the operator
-With vision-based communication system
Used for Diver/Robot Cooperation
4 bits of coded signal
1 bit of status signal
Command patterns can be captured by camera
Then decoded by computer vision schemes
Ethernet or serial link through tether

Miscellaneous
-Path Planning
-Seafloor Mapping
Altitude Package
Different levels of action (i.e. strategic, execution, tactical)

Good Mobility source: Underwater Robots Autonomous Underwater Vehicles

My Sources:
Good Link 1
Good Link 2 Im looking at the UWM3000, UWM4000, UWM7000; UWM4000 esp.
Good Link 3 Yeah, these are awesome: UWM4010 and UWM4020

Conclusion
Id say acoustic modems are our best bet. Seeing this stuff was really exciting. You can send images via acoustic modem. That is probably the most taxing of all the processes wed want our auvs to do. We want an acoustic modem that has a long enough range, not superfluous, a fast transfer rate, low failure rate (they all have that), and a low weight/low energy cost.

Acoustic rocks.
