This is the 3rd base fro my Drawing Robot.  This base lifts the pen up and pushes it back down at a high speed to create dashes while it drives forward.  A motor in the center of the robot drives a gear that turns 2 gears that are connected to each side of the robot.  The gears that hold the pen are driven in opposite directions. The bottom gear on each side is the drive gear then a small gear is placed between the top and bottom gears to make them turn in unison and in the same direction.

The machine is created completely by me (Tim Morrison) without directions.
