We tried out making a car that uses one motor and one differential
from http://netapps.marshall.edu/lego/lessonplans/SnowPlow/SnowPlow.html
on the LESSON Plan Page
It goes straight one direction and turns when the motor goes the other way.
The Cities and Transportation set does not have plates with ledges nor the catch
so we made some changes.
