wow that's amazing, why ruin it by smashing into another robot? save it for a art gallery and make a bad looking one to make other teams look normal. Good Luck!

Re: pic: 179 Drivetrain Teaser
 

When do we get to see what fits in that square center hole?

Re: pic: 179 Drivetrain Teaser
 

Very nice job Swampthing. Looks like a killer. :)

-Arefin.

Re: pic: 179 Drivetrain Teaser
 

Don't wory it will be quite Indestructable

Re: pic: 179 Drivetrain Teaser
 

hmmm let me guess:

It looks like i see 3 wheels on the side being shown (without your waffle tread) and most likely a multimotor drive...possibly more than 4 (total)?

The middle wheels are probably lowered a fraction of an inch (seems to be a general trend now)

Oh and it looks really really really sweet.

Re: pic: 179 Drivetrain Teaser
 

Pretty sweet Tytus...
Water Jet or CNC?
And...what is the big slit and square hole for?
I would guess that it was run by treads if the middle wasn't out of alignment with the other two. I can't wait to see the full thing up and running.

Re: pic: 179 Drivetrain Teaser
 

I think its for their Arm.

Re: pic: 179 Drivetrain Teaser
 

I would assume waterjet...cause I believe that is how they did last years bot.

Re: pic: 179 Drivetrain Teaser
 

boy howdy, that sure is purdy...

what material is that shell made out of? and how did you make it? it looks like it might be sheet metal thats bent and welded, but i can't be sure...

Re: pic: 179 Drivetrain Teaser
 

The hole on top is super duper secret (till week 5). The cover is 1/8 alum welded plate. Waterjet (thanks BTI). The front and back covers are hinged hoods. Under the front there is an isolated plugin electronics module. Around the perimeter and all through the base is a grid of 1/4" alum plate welded up, then laminated with 3/16 plate. It's extremely rigid. Also hidden in there are a brand new spiffy set of Andymarks. Around the lower perimeter will be covered in a very cool bumper sensor system. This little monster is going to see and touch!
But the best part is yet to come! :D

Re: pic: 179 Drivetrain Teaser
 

Where can I get one?

That is quite an amazing looking robot. I'd love to see the final product, with the arm (or whatever it will be) and all.

Re: pic: 179 Drivetrain Teaser
 

I assume you mean Andymark transmissions? Not wheels or planetaries?

Re: pic: 179 Drivetrain Teaser
 

the picture speaks for itself

Re: pic: 179 Drivetrain Teaser
 

lol hopefully you won't have to put any " speed holes " into it to reduce the weight :-)
would stink to ruin such a pretty water jet job/shell

Re: pic: 179 Drivetrain Teaser
 

how much does that thing weigh? looks heavy....but then again i could be mistaken....

Re: pic: 179 Drivetrain Teaser
 

Sounds like a challenge to me :D

You're not going to paint it that hideous fluorescent green, are you?

jk Ty - you know I love you guys (even Dan). Looks pretty sweet as always.

Re: pic: 179 Drivetrain Teaser
 

Awwwe, I feel warm inside.

She's gonna have a gloss black finish with air brushing to outline the cutout features. Green for the grass blades, white for the teeth and red for the eyes. The frame inside might end up red. Then the number plates etc in the vertical on the "secret" thing might get a different colored green than the tetra.

Weight: I've actually picked it up by myself with "almost" everything in it. So it's OK. I think when it's done it's going to nip the limit.

Andymark transmissions. Her technical speeds should be 14'/s high and 5'/s low.

We'll be driving it this weekend, I'll host a video at that point

Re: pic: 179 Drivetrain Teaser
 

...and we'll be driving, well, hmmmm :rolleyes:

anyway, can't wait to drag race ya (and play "chicken")! :D

Re: pic: 179 Drivetrain Teaser
 

My guess for the four corners is either powered outriggers or mast supports?

Waterjet cutting looks great, can't wait to post our teaser.

Re: pic: 179 Drivetrain Teaser
 

As promised, here she is on the move:

179 maiden voyage

She drives like a Cadillac. We also had big John lay down and put it in low gear and pushed him. He's about 280lbs maybe? but I don't know what the coefficient of Johns butt is...

I know the next question is, what are those pipes. I'll give you a hint, no they are not outriggers. And no that's not how they will look, they're just strapped up out of the way. No that's not part of our super secret rapid cap system.

We weighed it to be 90 lbs with almost everything. I think it's going to be 100lbs w/out the battery.

One more thing, I don't know if anyone noticed the perimiter shape (hexagonal). Let's see if anyone can guess it's function. The shape is credited to the very famous Warren Boudreau

Here's a better picture

Re: pic: 179 Drivetrain Teaser
 

Would those be some type of defense mechanism...? :rolleyes:

Re: pic: 179 Drivetrain Teaser
 

would those have any sort of similar final function to 111's 2003 robot??

Re: pic: 179 Drivetrain Teaser
 

defense: at times possibly, but no
111: nope

Re: pic: 179 Drivetrain Teaser
 

Tetra storage? Open up to hold tetras then grab them off with the arm?

Re: pic: 179 Drivetrain Teaser
 

mmmm....brings back memories of our bot from last year.....good luck with the end effect I know we had a problem fighting the weight and unfortunately had to resort to using a few HUGE pnuematics....very cool video though....gl see ya @ UCF =)

Re: pic: 179 Drivetrain Teaser
 

just like to say, that wasant me driving in that video. i drive much better.

Yes! i does drive like a caddylack and it pushes like a Catipler.

Re: pic: 179 Drivetrain Teaser
 

Wow. Very impressive. I like the way it "launches of the line" and accelerated well through its powerband. I hope ours drives like that.

Cadillac, I was thinking more like a V8 Ranger or maybe a Silverado. But perhaps one of those Cadillacs like a 1973 El Dorado with a 500ci under the hood.

How much does everything in the picture weigh?

Re: pic: 179 Drivetrain Teaser
 

I was thinking that too. But why would they need that powerful of a pneumatic cylinder. Unless for some reason they pick them up..

!!! Maybe that is why the bot is shaped like that :ahh: that way, so when they pull the rod things in..one side of the tetra will rest on the side of the bot. If this is the case, then that would mean their arm can reach both ways without turning (duh), and can hold more then four tetras on their bot at a time!!! :D

Re: pic: 179 Drivetrain Teaser
 

Right on the tetra holders. They can also be used for a few other things. As far as the shape, that's kind of a byproduct. But the actual exterior shape has more to do with interaction with other bots.

Here's another pic of electronical stuff

Re: pic: 179 Drivetrain Teaser
 

Well, they could also be used for lifting back up a flipped bot :) and also for defense to extend your bots length and width.

I have no clue what the exterior shape has to do with it though...time for some more thinking :]

Re: pic: 179 Drivetrain Teaser
 

I'm as they say, jealous. Wish i had access to a waterjet. Much kudos to you, and i'm quite intrigued by the prospective of a rapid tetra stacker. Got me rushing back to the drawing board modifying my design to increase its speed. Should be quicker now thanks to what you've implied ;).

Re: pic: 179 Drivetrain Teaser
 

Very nice. Reminds me of a tiger waiting in the bushes. Although i'm sure that will change with the addition of an arm :)

Re: pic: 179 Drivetrain Teaser
 

Had a little fun pushing today :D

Re: pic: 179 Drivetrain Teaser
 

Anti-tipping maybe? I'm pretty sure you guys will have some type of crazy arm.

Re: pic: 179 Drivetrain Teaser
 

now we have to find the coefficent of Nick's butt

Re: pic: 179 Drivetrain Teaser
 

sry, i don't know the coefficient of my butt. But if it helps i think i am around 200+ lbs.

(all the programming i do for my team just to be treated as dead weight for the robot to push ;) )

Re: pic: 179 Drivetrain Teaser
 

i wanna see this new baby of 179's --it looks great :)
you guys are doing well-- i must come and visit you guys really soon

tytus--don't kill me--that thing looks like it'll flatten me in a quick few secs

great job guys!!! i don't want to think how much damage you guys can create with that thing..

yay for swampthing again--they have done it again this year

Re: pic: 179 Drivetrain Teaser
 

You know we love you, without you, who could we use as a scapegoat? :rolleyes:

Re: pic: 179 Drivetrain Teaser
 

I am scared that you and Tytus, both will use me like that one day. :rolleyes:

but, VERY NICE CHASSIS!

Re: pic: 179 Drivetrain Teaser
 

I just watched that thing drive in the match videos from UCF, and it drives like a charm. Just a question, I'm assuming the center wheels are lowered, but how much?

By the way, conrats on winning UCF...the driving at the end of Finals Match 1 to get into the end zone was amazing.

Re: pic: 179 Drivetrain Teaser
 

The design was .2 lower at center. But I learned something about welding this year. Normally when you weld steel it pulls the joints together. But we found all the aluminum welding on this thing actually pushed the joints apart. So from the side view of this thing it did a banana shape a little over the length of it. So if you held one end on the ground the other ends wheels are almost 1/2" off the floor. So it's as if that center wheel is more like 3/8" lower.

And that last match was cool. It looked like a pinball machine how he bounced off everything but kept making progress back. Tytus is good at driving in reverse as well as Fwd. But I've watched that last moment a few times. It's really neat to see how pink made all the right moves to create the gap, and then it seemed like it hopped in there just so. That was actually the very final match of UCF.
Thanks for the compliments.
