While this robot was a second-round selection, it really didn't seem so in the actual finals. I've seen it in multiple occasions (including their games in our regional obviously), and it's an absolutely fantastic robot. I went full on geek over some of its subsystems, the elevator in particular was very impressive as well as the "special little surprise" from the final game in Israel's regional (for those who got to see it ). I'm sure their performance will gradually improve between each game in St. Louis. They definitely deserved the win and contributed a LOT to their alliance.

As a side note, while I only know two of the team's mentors personally, I got to meet some of their students and their dedication is just amazing, not to mention their proficiency in each student's field and in the robot as a whole. Wish you guys luck, you had a great run this year.
