These are very easy to make, and fun! If you know how to make paper dolls, you can do this freehand, using our instructions below, but we've made up instructions and templates with 2 sizes (PDF).
To make paper dolls, just fold a piece of paper in half lengthwise and cut along the fold, leaving 2 long strips of paper. Then fold one of your strips twice into an accordion fold (so you have 4 panels). Then cut out the shape of robot, making sure not to cut the edge of the arm on the fold. You can use a hole punch to make eyes, or draw them on.
Here is a robot shape (click on image to make it easier to see):
We made some mini-robots out of a scrap of silver paper (using a mini-hole punch for the eyes), too. To make a mini robot, you just fold your initial paper lengthwise twice, cut along the folds, leaving you with 4 long strips of paper. Then take one of the strips and fold it accordion-style into 8 sections. Cut the same shape on the top panel.
