Robo hamsters questions babaies?

Sounds like she might be pregnant. I would highly recommend splitting them up for a brief time until her babies are older. Male hamters (even robos) tend to be aggressive toward babies and might harm them. Also, as her due date grows closer, she will become more aggressive towards the male and may harm him! The female is pregnant for between 20-25 days so you should estimate when she would have babies if she is pregnant. You might want to keep your fingers in check around her at this time too because female robos have a MEAN bite and she may bite to protect her young.
