Claw "game" (scam) machines have deliberately-weak grasps, designed to drop the item they've grabbed whenever the arm is jolted — and then it's jolted at least once, usually twice, in the process of bringing it to the output bin. They are designed to drop their packages, so that people will feed in more money.

I'm not saying a drone with a claw arm would be the right design. But if it turned out that that was the right design, it would be designed not to drop its "packages", as opposed to the claw machines where dropping the package is the intended result.

Even the longest ranged helicopters are WELL short of "middle of the ocean" range. The longest top out around 600 miles, and that's straight line, not out and back, and certainly not with any loiter time in the middle.

> And how do you get people onboard? A drone with a robotic arm?

Nets. Nets are how you get people on board in basically all emergency scenarios.

Not that drone rescue ships seem like a particularly good idea, mind you.
