William is at a friend's house tonight, and last I heard, the plan was for them to camp out. They certainly have a beautiful night for it.
By way of making it up to Daniel, who wasn't invited, Karen brought home pizza, root beer, and ice cream, and Danny got to choose a movie to bring home from the library. He chose Chronicles of Narnia: Prince Caspian. And he's having a camp in, in our living room.
Good thing Karen doesn't have to go to work in the morning.
Danny and I also played with the Lego Robot that William built during the summer. We programmed it to sense when it bumped into anything, and respond by backing up and turning left before proceeding forward once more.
The first problem was that when it would go under something higher than its sensor arm, but not higher than itself, it would get stuck. We solved that by putting extensions on the arms to sense anything up to just above the robot's height.
The second problem was that the robot won't sense anything directly in front of it; you have to reach down and tough one of its two sensor arms. We haven't solved that one, yet.
Might have to bring William in with some of his Lego-building expertise.
