This bedding from Land of Nod is adorable and I'm sure you could buy one of the duvets to fashion into curtains or a bumper pad/bedskirt. The orange & aqua & grey looks really cute together.

this looks diy-able --

something simple you could do is find some paper you like and mod-podge it onto all your lightswitch and outlet faceplates. LOVE robot rooms!

I have actually bought many things from Etsy because I myself have been decorating my son's room and I love the robot theme, I bought those sheets from the land of nod and stuck with the grey blue and orange colors:

Also, I used etsy a lot when putting together my nursery. There are a lot of cute robot themed nursery items there. A quick search came up with crib bedding, prints and more -

Good luck - I love nurseries that are original and this seems like a great theme to me!

I DIYed the Mogi Robot Cabinet for my daughters room; it was really easy and only took a few hours. All the supplies were from Michael's.

Beasmom- How did you DIY the Mogi cabinet? It seems like the perfect addition for my son's new room.

How about these fun hooks at ROMP
