Inch Worm and Alien Dance

May 4, 2011

While the Robotics group built and programmed Aliens,

the building group made inch worms.

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.
