In a nutshell - use .NET Code to build virtual robots that can:
1) Navigate their way through a maze with hidden traps and surprises
2) Explore a virtual Martian surface
3) Navigate a car though an urban setting
4) Rescue a person trapped in ruble after a major disaster
5) Sumo-wrestle another robot
