Welcome to the forum.
keeping a pair of dwarfs can be difficult. If you've never had hamsters before, I strongly recommend keeping one first.
But robos pairs are adorable and hard to resist, I understand that xD so here's the basics on keeping pairs.
Your main goal when housing a pair is to prevent fighting as much as possible. Select a cage that has at LEAST 360 square inches of floor space (more is always better if you can), with no shelves, or outside attachments. If the two don't get along, one hamster might 'claim' a level or attachment for itself, and fight the other if they try to come in. One big open space prevents arguments over territory like this.
Pairs need two of everything; two wheels, two water bottles, and enough hidey holes and houses that they can be apart from each other if they need to.
Feeding can be a bit trickier. Some say you should scatter feed pairs, to prevent them from keeping food from each other. Instead of putting the food in a bowl, you just sprinkle and scatter it around the cage or tank for them to forage for. Others say that using two bowls is fine too. Whichever method you use, most people who keep pairs feed about 3 tablespoons of food at a time, to make sure each hamster gets enough.
All their toys and hideouts should have at least two entrances. This way one cannot be cornered by the other. It can be difficult to find toys at the pet store with two entrances, but it's easy to make them, out of cardboard or food boxes, or wood if you're a bit handy with tools.
Lastly, it's very important to have another cage on hand, because if they fight, they need to be separated. Pairs will sometimes have little squabbles, and that's normal, but if they ever draw blood, or if one starts bullying the other needlessly, they should be separated immediately, and should NOT be reintroduced. If that happens, you should let them live apart from each other from that point on. It's a possibility that everyone who considers keeping pairs has to be aware of: some hamsters just aren't compatible together.
I hope it goes well. Though it can be tricky, keeping pairs can be very rewarding. Robos are naturally pretty shy of humans, and some won't be happy to ever be picked up and handled, but they're so cute to watch run around and play <3
