Nothing's impossible, if your team can believe in that, any team can make Einstein.
Do some teams have more factors in their favor (call them "Elite" or "Powerhouse" if you'd like)? Sure but it's not just resources that build you a solid machine, train your drivers and help you at competition.
Nor does size of your team. 100 students is great, but is just having that many students give you that big of an advantage over a team of 10 - 20 committed kids?
It's the amount of resources you have, it's how you manage them.
In the end, Einstein should always be a goal, even if it's not your active one. My team's been around the block a bit (20 - 22 years depending on who you ask

) and we've never been to Einstein but our goal is to build a robot, have fun while doing it and compete at a high level.
With that said, we can't wait to show off what we've built this season in a couple weeks and (fingers crossed) we perform well enough to earn a blue banner.
