Marble Powered Robots

These are some paper robots powered by marbles. When you put them on a slope they roll down very quickly. One is based off the Instructables robot and that's the one I'll show you how to make. I built them because I like robots. Here's how to make them.

Thick paper

Glue

Pipe cleaner

A marble (about 15mm diameter)

Pen

Scissors

Ruler

Thick needle (for scoring paper)

Print out the template on thick paper and cut out the parts. You may need to enlarge the hole at the bottom. Then score the fold lines.

Fold all the tabs and glue the pieces together. Don't forget to put the marble in before closing the body.

Cut a piece of pipe cleaner and poke it through the body to make the arms. You may need to make a hole with something else (like the point of a compass).

Cut some thin strips of thick paper for legs and glue them on the bottom. then draw whatever details you want.

Make as many robots as you like and race tham down a slope!
