Air Vent - Automation

The next project I wish to tackle is automating the air vents in the house. The regular air vents are easy because I see that there is someone making this already. http://starlinepc.com/index.php/z-wave/vents-registers.html BUT upstairs all of my vent are an irregular style. Like this… http://www.lowes.com/pd_473351-49069-20137___?productId=4686137&pl=1&Ntt=wood+air+vents Inside is a small wood door to shut off or lift up to open the vent. So I’m thinking I may need to make some sort of arduino custom thing to open and close the door inside. Just wondering if anyone has any ideas on how to do that.
