If a full robot body were available, I’d jump on it right away, but ONLY if it has absolutely no way to wirelessly communicate. Absolutely the sole way of interacting with the software would be a single USB port inside a panel in the body with a physical lock.

There's a pretty good movie to be made here.

B plot has a bunch of injured vets, many with these limbs, picketing congress and marching around inside the offices trying to petition lawmakers about getting benefits that they're owed but are being stalled by budget talks.

A plot could be a spy thriller, John C Everyman investigating evil tech bro over whatever nonsense. Finds out all too late that the evil tech bro owns the company manufacturing those limbs, and wants to install a puppet government. The only way to stop them is to literally shut them all off remotely. The vets are running all over, unable to stop themselves, attempting to lock down and assassinate representatives.

Everything resolves as hundreds of injured veterans literally fall limp all over the halls of Congress. The media eats up the protest, the vets get their benefits, John C Everyman goes on to pick up another case. Evil Tech bro lives to plot again. Or dies being ripped to shreds by his own limbs. Who cares.

Tightbeam line-of-sight IR laser should be the only way to control stuff like this. And I realize that means I can't control my hands if they are in another room, which is a delta of 0 from the current human condition.

Wireless is overrated anyway. I would want a winch/cable and copper signal line.

That way I can grab things at the bottom of the well and retract the hand.
