A fairly common approach for a rookie team is to build a "stock" chassis and then be creative with attachments and programming. That's what our team did our first year. Gives them a quick start-up and something that can be programmed - but lots of flexibility in what they do next. I think we used the basic tri-pod chassis that is shown in the commercial Mindstorm set.
Have fun!

For the tournaments, check out how the team will be judged during the Robot Design judging by reading the appropriate Rubric: http://www.firstlegoleague.org/sites/default/files/Challenge/Combined%20Rubrics.pdf, specifically, the design and innovation section. Your team might do relatively poorly during the judging. More importantly, you might be depriving your team the opportunity to be creative, explore and invent. That, to me, is one of the best parts of FLL!

The only criteria mentioned is that the robot must have "crossed completely over the west line of the noted region, from the west only" (well, the update also requires that all contact with the mat be south of the northern edge of the obstacles). Being "in" an area east of the line is irrelevant to scoring the obstacle mission.

The robot often gets a bit skewed when crossing the obstacles, so what does completely crossed over mean? Specifically, what if some portion of the robot not in contact with the mat is outside the colored zones? Next case, what if one of the tracks / wheels does not cross the obstacle or half of the wheel crosses but the other half is out. Last case, once the robot has crossed the line, what portion of the robot has to be inside the zone: all of it (how defined?), the part in contact with the mat, or just some of it?
