Drone - controlled via VR

[APARTHEID]

Simplify! Instead of a specialized shell, why not allow the Roboticists to cram a remote signaller inside a borg head to make it remote-controlled? It'd give a way to use braindead borgs or similarly disassembled ones.

That would make it too easy. You get all the advantages of a Borg without any of its downsides (e.g. law restrictions).

There's one big disadvantage: you're still prone. Your dorky body is still back there making borg noises and wrench hands.
