As I said earlier, they are one of the most scientifically-advanced races in Tamriel, so they may have figured out some clever way to construct them unknown to other races. Examples could be ancient long-lost automatons whose designs were lost in the passage of time, some undiscovered secret way of using soul gems, et cetera. There are so many possibilities, I must stick to the facts rather than speculation.
