sweeeeeeeeeet................kinda large tho... guessing its for big wheels????to gear them down a LOT..
is it water jetted out?

Re: pic: Swamp Thing's Sprockets
Yeah....nice job on the sprockets...i personally like them and would like to get a set for my team but...just wondering who made them? I thought that this was supposed to be a highschool preoject...were the kids design, fabricate, and test the robot all by themselves. On my team..we have mentors to help us with complex problems but for the main part, all of the designs and deciosions are made by the team captains. This way when our robot does awesome at the competittion we can say, nice job guys, to each other, rather than having to give all the design credit to some...I dont know know if im barking up the wrong tree...but i just wanted to know if some one ( a student) actually made these, or were they made by some pro.

Re: pic: Swamp Thing's Sprockets
well yes, the robot is designed and built by the students, but I know a majority of the team, like ours, has machine shops to do complexed designs for us which our lab cannot do (ie.. cutting out precise holes and such in our drive train to lessen weight, and still give it a profesional look).

Re: pic: Swamp Thing's Sprockets
In 2002 we were lucky enough to have an extremely high tech machine shop (a subcontractor for Boeing ... they had CNC equipment left and right) working with our team.
We created some motor mounts that are probably equally as pimp as that gear.

Re: pic: Swamp Thing's Sprockets
Don't assume that all CNC and milled-out pieces are engineer-designed an machinist-made. My team, for one, has a core of machinists who are trained on manual mills and lathes, with a specialized group of three people (including me) who are trained on the CNC mill. Our sponsorship from a nearby machine shop consists of them letting us use their tools, with the stipulation that they're too busy to make parts for us. All of our parts are student-designed and manufactured, but they're very high quality.
However, if you accuse our robot of being engineer-designed and built, we'd be flattered 
Very nice sprocket btw. I count only two bolt holes - that enough? Are the holes made by waterjet too?

Re: pic: Swamp Thing's Sprockets
Please all:
Do not turn this thread into an Engineer vs College vs High School debate.
That has been debated enough.
The two sides of the argument are:
HS Built) Kids learn more by doing.
Eng Built) Kids learn more by seeing things done "right".
Neither can be proven either way. Each individual is different. I've been a student on two teams. One which was 90% "Adult" designed/built, and the other which was 90% "HS Student" designed/built. I won't say which I learned more from because I am a unique person with a unique experience.
As to that specific sprocket, two retro words:
Way Cool.
I'm pretty sure Tytus designed this, as he states he drew the "Eyes" in AutoCAD "last night" from the post date. To my knowledge, Tytus is a high school senior with CAD experience. The piece was cut with a water-jet at BTI (One of 179's sponsors). So your comment about the engineer built product is irrelevent. The water-jet machine (seemingly) loads the AutoCAD file, and makes its cuts where lines are in the drawing file.
1) Was this water-jet cut piece necessary?
2) Does it look really cool?
3) Could they buy an off-the-shelf item that does the same function?
4) If so, does it really matter who manufactures the product?
1) No.
2) Yes.
3) Yes.
4) No.

That is very awesome. We just got sponsorship of the largest lasercutting company in the world so we should have some nice stuff in store as well.

We got a new sponsor who'll be water jetting parts, field trip for the team to see their autodesk pics being made into parts. We're finally getting better at autodesk.

Student designed and built? Go for it. One of these years you may decide you want to explore something more and work even more closely with mentors.
Lots of engineers, teams do things differently, and it's all good.
You doing all your own welding? We didn't, til last year. We have 5 student TIG welders this year.
A mentor was doing the web til last year - it was me. *chuckle* I'm no pro. No student was inspired to do it til last year. Our student webmaster is the pro.
I'm doing the public relations. However it's rubbing off on other team members, and now some of our shyest members can walk into a congresswoman's open house, the new school superintendent's open house, and schmooze with the best of them.
There's much more to the FIRST program than just building the robot, and FIRST gives you the freedom to explore all of it at your own team's pace.

Re: pic: Swamp Thing's Sprockets
Major kudos to you. I can't wait to see what you'll do with the rest of the bot if you spend that much time on a sprocket.

I'll bet it took less time than ordering from any given company.

Re: pic: Swamp Thing's Sprockets
Thanks all,
The night before wathejetting i got an email that said "Watterjet confirmed" Immideately i got on autocad and thought of whatever i could do and draw for the engineers to put into the watterjet, The Eyes And the "Speedholes" are mine we were watterjetting at BTI Inc down the street from our school For SEVEN HOURS!!!!! Alot of Parts We Are SO Greatfull We Even Put BTI watterjetted into our chasis The sprockets are Real bling! i cant Give any clues as to what theyre for yet But Rest Assured It Will Be awesome

first... im a jounior, not a seinor
I didnt draw this sprocket Dan Quiggle(Prat&Whitney, Under EDF INC) Did Tho i could draw sprockets fairly easy
The eyes are my creation they are scaled down from my orignal verson witch can be seen on another piece of the Bot
YES Its Made of aluminum
Yes, It was nessarry to have them watterjetted, Unless we wanted to spend 36 man hours a sprocket on them and the alumionum sprockets weigh a half pound each compared to a steel one off the shelf would weigh 2.5 pounds
NO, you cant know what theyre for yet
Yes, The waterjet machine is awesome
NO, we cant afford one the machine, the 50HP pump, the watter softener, the abrasive sand, matinance, sound ordnance permits, ETC...
BTI Is like a sponsor they dont give us money but they let us do watterjetting and some machaning we can't do ourselves .and gave us a tour of their shop And they gave us students alot of knowledge about machaning
and Am i realy that mysterious that Breandon Speculates about me?

Re: pic: Swamp Thing's Sprockets
We are lucky enough to be making our own sprockets this year as well. We have CNC Software(Mastercam) as a sponsor this year and so we will have as many sprockets as needed. And the program isnt that hard to use. I picked it up for the most part in about 3 hours and we had our first sprocket done today. So hopefully we can make use of the tool and have things as nice as that one very soon. LOL. CNC Software also donated a CNC machine to our team and we have that at one of the high schools where we build and fabricate our machine.

Anyway: very cool, Tytus! Great way to lose some weight on the sprockets, as well - it looks much nicer than "swiss-cheesing" it.
