Depends what you’re going for but you can do a robot with a cardboard box, if you don’t have one large enough ask around the local shops they often have ones they are throwing out. All you need is the box and some foil and a bit of paint and you can make whatever robot you like. (Think tissue boxes for feet etc)
If you want something quick and easy you can also go as a present and again all you need is the box and some wrapping paper (maybe save some from presents).
A box can also make a great book costume just paint the outside to suit the book you’re going as.
