6. Scratch Robots www.build-it-yourself.com Motion Module – Step 1 1.Place the motor on the smaller block of styrofoam. 2.Put this near one end of the base (leave room for the battery). 1.Screw a foamie strip over the motor (do not glue to motor), through the styrofoam, and into the base. 2.Repeat for other side.

7. Scratch Robots www.build-it-yourself.com Motion Module – Step 2 1.Attach the battery clip to the motor on one end, leave the other unconnected. 2.Make a small pocket for the battery to slip into with a foamie.

8. Scratch Robots www.build-it-yourself.com Motion Module – Step 3 1.Glue the pencil or wooden dowel to the motor.

9. Scratch Robots www.build-it-yourself.com Motion Module – Step 4 1.Shove the pencil through the block. You may want to make the hole bigger with a drill or insert a thick straw to reduce friction.

10. Scratch Robots www.build-it-yourself.com Motion Module – Step 5 1. Drill a hole through the bottle cap. ALWAYS PUT SOMETHING UNDER WHAT YOUR DRILLING!

11. Scratch Robots www.build-it-yourself.com Motion Module – Step 6 1.Slide the bottle cap over the pencil to the spot you want and glue it down.

12. Scratch Robots www.build-it-yourself.com Motion Module – Step 7 1.Glue a short foamie strip onto the popsicle stick. 2.Glue the Remaining end of the foamie to the styrofoam block.

13. Scratch Robots www.build-it-yourself.com Motion Module – Step 8 1.Attach you WAY COOL CRITTER to the popsicle stick, and voila!
