Looks great guys! Another innovative drive-train implementation and once again I'm impressed. Care to elaborate or point me to somewhere to show me how it works?

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Being reminded of why 1625 is my favorite team in FRC- priceless.

That drivetrain. You crazy.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Correct me if I'm wrong, but do you guys have TWO drivetrains? One for forward/back, and another for strafing?

I am at a loss for words due to awesomness.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

I have no idea how it works and I'm not sure if I am better off keeping it that way or not.

How do the strafing wheels come into play?

Why telescope instead of a higher arm joint?

Why is your arm joint a four bar kind of thing I'm so confused

WHY HAVE YOU TURNED MY WHOLE WORLD UPSIDE DOWN THE DAY BEFORE SHIP AGAIN

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

That's pretty beastly, Good job guys.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Cant wait to see this thing in action great looking bot.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Impressive.

Any videos of this thing in action? I'm really curious about how well your drive works.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Seems to me like 1625's "lobster" drive shown here, is a relative of 148/217's Slide drive (Nonadrive) from 2010, at least in how it works. It looks to me like the strafing wheels are actuated up and down to lift the other 6 traction wheels off the carpet.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Looks ridiculously awesome as usual.

Telescoping arm + roller claw remind anyone else of 233 in 2007? If that's any sign of things to come. . . well, watch out!

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

I get how the lobster actuation works (downright ingenious imo) -- the front/rear wheels are the rotation axes for the lateral wheels. Yet what really blows my mind is how the belt running between the two lateral wheels ('lobster wheels' ?) doesn't get eaten when the robot turns in place during normal operation. Is there a differential not shown?

Awesome work!

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

I'm hazarding a guess that the left gearbox is chained to the front wheels and the right gearbox is chained to the back, or something similar.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Ahh, that would do it.

Re: Team 1625 Introduces their 2011 Robot: Mr. Cringerpants
 

Looking good 1625! Your robot definitely has a unique look and feel to it. I'm excited to see how you do in competition, and how fast that minibot makes it up the bar ;)

Glad I'm not going against that anytime soon.
