I wanted something that was 1) cheap and 2) easy. After looking on the internet I decided it would be pretty cheap and easy for me to make my own R2D2 costume. Here's how I did it.
2 pieces of large poster board
cheap plastic helmet or bowl
First off I started by drawing R2's markings on the poster board. Then I colored in the markings.
I added some accents to the body with duct tape
Next I spray painted the helmet and once it was dry added markings with blue duct tape. I also added one of my bike lights. This one blinks so I most likely won't turn it on since I don't actually want to blind my friends. I also used black, red and silver tape for accents on the helmet. I used a cheap plastic "police" helmet and turned it backwards.
My next step was to take a second piece of poster board and attach it to the first one so it formed a tube. This picture doesn't show them but I added shoulder straps with elastic.
So far the costume is doing it's job in that it was 1) cheap and 2) easy. It is also funny which I was hoping it would be too.
If you didn't get your Halloween celebration on this weekend and you are still scrambling for a costume I think this could easily be adapted for other robots.
I did consider being Maru the Cat for Halloween but didn't know if everyone would know who Maru was. But it did inspire the R2 idea.
