Introducing our 2012 Team 48 competition and practice robots, xtremachen15 (aka “Howie”, aka “Kyrie”) and “Andy”. Go Cavs.

The feature of this bot that sticks out the most is the tilting cage/shooter [strike]that doubles as the bridge tender[/strike]. Also, with the cage tilt, CG is never an issue on the field.

Are those blue pool noodles centering the ball in the elevator?
Looks great guys, can’t wait to see it in action.

Indeed they are, backed by lexan. They seem to do the trick. We’ll have graphics applied to hide the velcro.

Would you prefer pink? :slight_smile:

I would prefer purple and blue tye dye please.

Can I get some orange? Looks like another great machine for 48 this year!

That’s why it looks so familiar! We have the same noodles, same color, doing the same thing on our bot (although ours is quite a bit taller).

Looks great! See you at Pittsburgh.


Wow, great job! Looking forward to seeing you in Cincinnati, congrats to your team.

Looking forward to seeing many good friends at our regionals this year. Good luck to 1038 at Smoky Mountains Week 1 - we’ll be watching! :slight_smile:

We do have a few new vids - nothing overly special yet. Made a mechanical tweak to the shooter wheels today - definite shot consistency upgrade.

Just a clever and unique design. I’m excited to see how it works out.

New vid links with the most recent testing. Adding our new retractable shooting hood not only permits topspin lob shots cross-court, but also seems to have improved shooter accuracy and efficiency in the normal backspin mode.

Lets hope 48 and 279 get to be in the same alliance multiple times.

Now that the regional season has ended, I wanted to share some information and video links of Team 48’s competitive season for the benefit of any St. Louis scouters (cough hack and FRCTop25 voters cough hack cough). :wink:

Team 48 Season Summary through end of regionals:Ranked 25th out of 2332 teams with an Adjusted OPR of 26.7 (Ed Law)3 Regionals Attended, 2 of which are considered by many to be 2 of the more competitive events this season. Consistency in Hybrid Scoring/Bridge Balancing and steady improvement in Teleop performance was the name of our game this year.We have a triple balance assist device onboard and will continue to prepare for its usage heading into St. Louis - we will be ready to be a part of any “double stinger” triple balance alliance.

Wisconsin Regional Elimination Round Highlights:http://www.chiefdelphi.com/forums/showpost.php?p=1153318&postcount=3Thank you to all team members, sponsors, parents, and other supporters of our program for working so hard to get us this far in what has become our best competitive season ever. Here’s hoping we can put on one more entertaining showing at a fun and successful Championship Event! :slight_smile:

So I needed something to do tonight:

xtremely legit.

Looking forward to see how you do in STL.
