So military and domestic drones will be old hat in setting; since giving motion to the motionless is sort of -the- thing here. Initially they were crude; sailed spears and the like, nowadays they're ahead of the curve if compared to real life robotics. The limiting factor I'd stress being that they're only as intelligent and well behaved as their animal component. It's the sort of world where your car could get sad because you don't wash it. Unsurprisingly this makes taming a lucrative (and cut-throat) industry.

These 'drudges' preform best if structured similarly to their component creature: guard dogs, birds of prey etc. Though it's not beyond a good trainer to acclimate them to an unfamiliar form. The simplest of such being self driven gears and living engines, the cornerstones of modern living.

Speaking of modern life (and that's as good a segue as I can manage at the moment) Transportation is something I've been mulling over.
