I think it would be neat if the game field had multiple levels to it, and it would have stack-able game pieces that the robot would have to stack, then drive up to reach higher levels where it would then accomplish a second objective.

Or, perhaps if the game field or the drive team were completely concealed, having no physical view of the robot, requiring them to rely completely on cameras and sensors on the robot in order to maneuver around the game field.
