Roborovskis aren't actually prone to diabetes, that's only hybrids, campbells and chinese hamsters, but there's no harm in using a low sugar diet. Don't use the ball, which you pictured, as Robo nails can get caught in the ventilation holes. A playpen is much safer and can be made from anything. I would recommend a short cage, so they can't fall off the bars. Roborovskis are also the hardest to tame so you may end up watching them more than handling, different to the other species of hamsters.

What do you want to know specifically about Roborovskis? I can't really help more unless I know what you want to know because there are so many aspects of hamster care.
