Inverted Pendulum
Balance a 1-meter long yardstick above you. You’re not allowed to hold onto it tightly. To simplify this, we’ve built a base holding the yard stick that only allows it to swing forwards and backwards (no side-to-side motion).

Cat Herding
A level, enclosed space has a hundred ping pong balls placed in it. In the center of this space a 2’ diameter circle is drawn. Build a robot that herds all the balls onto the circle. Extra points: Stop when you know you’re done.

Sheep herding:
Within a confined space a number of lighted bumble balls (http://shop.store.yahoo.com/discounttoys/ej34693.html) are set loose for a bot to herd in to a pen within a certain amount of time.

Wagon push
Push a standard wagon six feet across the finish line. The wagon will have four wheels, the two nearest you are steerable, the further two fixed. The wagon will connect to your robot by a downward pointing axle, four bricks off the floor, and three studs long. The standard wagon will be twelve studs wide, and thirty-two long.
