Last week, we built Lego alligators. Today, we are plugging the motor and sensor into the USB port on the computer to make it crunch and move the jaw up and down as though it is chomping. We logged on to our computer and went to the Lego WeDo software. The software gave us instructions that made us be able to control the alligator robot. Then, we made it sense food so that the jaw would open and close as the food approached. It was very cool. I hope we get to do this again!
