With some modules, you'll have to experiment with the programming to make them work the way you expect.

Lifter


	We use this as a way to move a ball or something up up up -- it could also push something down.

	This is the lifting module with one of the sides removed so you can see inside.

	Use this photo to make sure the motor and gears are at the right height. Notice the little yellow spacers that hold up the motor.

	We used a lot of bricks to build up the height so the arm could swing all the way around. ( This means that the program can just turn on the motor without stopping if the arms hit the bottom)

	You can use other parts for the arms. These have a little bend that lets them 'cup' and object to hold it as it moves.

	This is a pretty simple program. It waits for a sensor input then turns the motor on.
