Wireless ROV

Amazing tech. Apparently can work off reflections and back scatter so it's not restricted to line of sight.

That is sweet! I wonder what happens if more than one ROV is in the water? I bet poor water clarity reduces its range.

the same with your TV and stereo at home, signals from different transmitter are modulated differently to match a particular receiver.

Well it's probably the same thing happens as when you have a remote control for your TV and a remote control for your cable box.. but yes I'm sure water clarity has a lot to do with it working correctly. And I remember a well noted model submarine manufacturer looking into a light based control for model subs .

Hmmm... up to 50m range... in a perfectly clear swimming pool? Won't work worth spit in a real body of water.

This looks like an expensive pool toy. Working ROV's use umbilicals and lots of power.

During pre-deployment checks on a job once, the ROV operator used one of the $500k Titan manips to swing a Thor-sized sledgehammer around like it was a feather. They could tie knots in #10 thread all day long in a 5 kt current.

The Navy has worked on secure, laser-driven, short-range comms for years. Still waiting. . .
