Overview

Don't waste your own energy throwing paper balls at your enemies! Let your bot do it for you.


Steps

1  Gather your Cubes, LEGO®s, and other materials.

2  Stack the Motor Cube on top of the Battery Cube so that the Motor Cube's axle and the Battery Cube's switch are on opposite sides.

3  Place the 24-tooth gear on the Motor Cube's axle.

4  Insert two pins side-by-side into the 24-tooth gear.

5  Place the 12-stud beam partially on the 16-stud beam.

6  Tape your cut-up paper cup or bowl onto the end of the 12-stud beam.

7 Attach the 16-stud beam to the two pin connectors on the 24-tooth gear. Turn your Battery Cube on and let the fun fly!
