The top is definitely (or from what I can tell from the quality) is male. He's not swollen, those are his testicles. It's hard to sex robos, but typically the "belly button" is higher up the abdomen, and is the male's external sex organ, the penis.

The female's parts are all internal, obviously so the "belly button" type bump is usually right above the anus. Sometimes the belly-button looking appendage is higher up than you might think, and can be in between what is classified as male or female, making it hard to determine the sex. I had this problem with my robos.

I really hope you don't have them housed together, though. If so, you can almost guarantee your female is pregnant.

Notice the yellow-colored fur in the top photo--it's from the secretion of the male's scent gland. Male = photo 1; female = photo 2.

You can always visit an exotic vet who will sex them for a low cost or free. I've met a lot of vets that would much rather take 5 minutes out of their day to sex a hamster than have you have a pregnancy on there hands. The bottom picture does look like a female because I can not see a penis but you never know, every hamster is different.
