I was watching this video of an underwater clam shell gripper that the author describes as a device which is a:
"Cheap and simple device to explore the sea bed from a boat. Ideal for catching shells, crabs and other bottom dwellers.
A robotic device with a clamshell gripper arm and a HD underwater camera.
Hand held monitor with controls to zoom and tilt camera and to control the opening and closing of the clamshell gripper arm."
This got me thinking...my father loves crabbing out of the Siletz Bay on the Oregon coast, and crabbing is like most fishing sports to me, boring, boring, boring. Throw object in water, wait, wait, wait some more and then pull said object up and hope something is now on the trap / hook.
Anyway, the basic question I have is: "Can I use a tele-presence device such as an ROV to go out into the bay and just take the crabs directly instead of waiting for them to stumble into the trap?"
To me this would be like how sailors must have felt when they stumbled upon Dodo birds. "You mean I just walk up to them and grab them????".
I'm sure it's not that easy to chase a crab down, but at least there is some adventure and adrenaline now involved.
