Could be interesting....although this was achived over 10 years ago, I was only wondering if anyone had any ideas on the communications aspect of the ROV? is it being more widely used these days?

'Market research carried out in early 1996 showed that there was a potentially profitable market for a low cost Remote Operated Vehicle (ROV)(...)
The main breakthroughs were in the application of the ultrasonic communications link for controlling the autonomous robot and its ability to send data at a rate sufficient to send near real time video from the ROV. This was tested in a number of filed trials around Hong Kong.'
The breakthrough was brought about by design of a robot that could work in a hostile environment (under water filled pipes)
