Lego sweepers

Part of the Lego engineering curriculum the girls have been soon is building simple machines.  Their first task was to build a machine that would sweep up "leaves" the most thoroughly.


This was a cool task because they did the test with their machine sweeping the "leaves" and found that it didn't work as well as thy thought it should.  So the. They had to experiment with more arms in different positions at different speeds to find the design that swept the paper the best.  Now they need to make this machine for our yard!   ;)
 I came home from work one day to this.  I will use it as leverage one day when a certain young lady probably won't want it shown.  Or maybe she'll be a good sport about it.  The picture makes me smile either way.
