While the Robotics group built and programmed Aliens,
the building group made inch worms.http://netapps.marshall.edu/lego/lessonplans/Inchworm/inchwormprint.html
The most important part of the Inch Worm is the pawl and ratchet on
each axle
The pawl and ratchet are to be set so that both the front and the back
wheels roll only forward.
Each program was to start with a signal to the light sensor.
Then there was music and motion.
The contest went two rounds
with terrific success all around.
