Lego Stop Watch

Build an “analog” stop watch using Legos, motors, and rotation sensors.

Vending Machine

Build a machine that accepts pennies. When a penny is inserted, the customer can choose from three items by pushing a button. The machine then delivers the item (like a marble) to the customer. You could also make a dispenser that delivers one item for a nickel and a different one for a penny. Another kind of machine would deliver a different number of marbles depending on how many times a button is pressed.

Robot Navigation

Figure out a way for a Lego robot to know where it is at all times on the 4’ x 8’ competition track to an accuracy of plus or minus 1 inch. Does not have to use just LEGO pieces.

Music Reader

Program a robot to read bar codes and play the note associated with them. This means you can write a song just by rearranging the bar code sheets in the order you’d like.

CanDo Extreme

Program your robot to do the CanDo Advanced challenge with a twist. Cones with green stripes on them should be put in the base. Cones without stripes should be pushed outside the circle.

Robot Research

Do research into how accurate various robot designs are in preparation for the robot competitions in the fall.

Can Crusher

This device accepts empty soda cans and crushes them. To count as “crushed” a can must be at least half the height or width that it was initially.

Orchestra

Combine the DrummerBot and at least two other musical Lego creations and modify them to be controlled via Infrared by a central “conductor”. Play a musical piece with all of them working together. Consider combining it with the Level 3 Music reader.

DrummerBot

Build a device that can play the Drums. Drums can be made out of Glad Wrap over wheel hubs. Your device should have two drums and a cymbal made from something you find around the house and should be able to play an entertaining drum solo, not just a bunch of noise.

Lego Musical Instrument

Make a musical instrument out of Legos.  This could be anything you can dream up.  Some ideas are a trombone, piano, drum, xylophone, player piano.
