Cool video, hopefully it can be done by someone.
A large heavy 2x6 Auto-Sentry you "throw" at a max of one space would be cool, maybe with a short targeting range, no movement. Like a high end proximity grenade.
I like the video's idea of a flying-probe unit, keeps the use limited as a tool.
I wonder too though if it might be possible to have a mind-control device just for machines, so you lose a soldier's TU on a radio-control-device to make use of a robot for a turn.
I'd like to use drones in my games, but I think I'd end up not using them at all, so I can train a disposable rookie.
