"Simply" awesome!

Thanks for sharing, Karthik!

Re: pic: Team 1114 - Simplicity in Design

It's documents like this that make even us business majors really appreciate how utterly awesome a mechanism or robot is. (254/968 last year won the prize for their gearbox poster.)

I'll say it: 1114 is serious business.

That was my guess. You can clearly hear it even on webcast matches when your arm rotated. Must be pretty loud.
By the way, how did you get the 72 tooth sprocket? Go-Kart type? We used an 84 tooth last year and 72 this year and that's the most common question we get about our robot.

It was a custom job, machined out of aluminium on their CNC.

This machine truly embodies "simlpicity on the other side of complexity"

As a rookie team, we've noticed that simplicity pwns complexity...:)

I would say their '06 bot was fairly simple, but when you look at their mechanism this year its what, a single joint with a roller manipulator and a 'punch' kicker (its pretty simple mechanism), I would say their bot is a very simple solution to this year's game. When you compare it to what a lot of the other 'top' teams came out with looks fairly darn simple to me, maybe its just the machining quality that makes it look more complex then it is.

I am still surprised that no one came up with a similar concept, the closest i've really seen is 1625 (and their great bot is still far more complicated). Some bots use similar pick up, but very few teams use the pokie type of launcher that fits so well with this design.

That robot is simply amazing. Its definitely one of those robots that i look at and wonder "how did i not think of that?"

The closest our team came to a shooter was a pair of skis... it launched the ball a fair amount (almost too high- it would hit the ceiling in our practice arena), but was extremely unsafe and lost the ball often (hence why our current bot keeps an iron grip on things).

Id say you guys pulled off the shooter concept wonderfully. You guys get an ÜberStar:

I dunno, our shooter is pretty simple if you get a good look at it. Our drive train is much more complicated, being a swerve and whatnot, but our shooter cocking mechanism was inspired by a Lego creation of one of our seniors a few years back (yes, people still play with Legos :cool: ). We had JVN down at our pit at the Wisconsin Regional having an infamous "why the heck didn't I think of that" moment in relation to our shooter.:D

ps: Kudos to 1114 for dominating, btw. Your entire setup is sick.

Re: pic: Team 1114 - Simplicity in Design

This may seem a little bit late, but could I get a description of how the winch works?

I'm kind of confused about how they pull the bar in?
