You really do need to separate them completely now, cardboard just won't do it, they will need a cage each, robos generally do ok in smaller cages so if you're really short on space better to have two small cages than risk any more injury or even death.

They may be a little stressed by the change but will soon adjust to living alone, it is actually more natural for them to live solitary lives so don't worry about that.
