Re: Pic: Team 935's nearly complete chassis
 

please don't tell me you fabricated that entire frame :yikes:
it looks awesome


very nice, GL with the meca's

Re: Pic: Team 935's nearly complete chassis
 

Beautiful indeed.

Re: Pic: Team 935's nearly complete chassis
 

Is it just me or does it look like that no matter what way you put it down that the wheels don't touch or that the chassis will be very, very low

Re: Pic: Team 935's nearly complete chassis
 

Im pretty sure if you just put that on the field, had all your drive team have slightly annoyed looks on their face, maybe so red lights, you could win by sheer intimidation.

awesome job on the frame guys, wish ours looked that good.

Re: Pic: Team 935's nearly complete chassis
 

That looks awesome. we were going to use mecanum wheels, but that was ruled out. our frame is probably 80/20 again.

Re: Pic: Team 935's nearly complete chassis
 

As well as being fabricated within a week, the chassis is very low, and touches the ground. Thanks for the positive feedback. :cool:

Re: Pic: Team 935's nearly complete chassis
 

are you guy afraid and take note that the ground is not exactly level? around the corners and middle area the ground is above so that the railings have something to attach to so they don't fall over.

i tried to get a drive base as low as possible until someone told me that and i went, oh no.

Re: Pic: Team 935's nearly complete chassis
 

We have the same height we used last year, but we ended up cutting off the front / back corners so we could climb ramps. Right now, we're about 7/8" off the ground.

Re: Pic: Team 935's nearly complete chassis
 

from the look of things you might......... want to downsize it a bit.

Re: Pic: Team 935's nearly complete chassis
 

Following up on that...



And the wheels...



Again, feedback is good.

Re: Pic: Team 935's nearly complete chassis
 

Ya, I'm not sure what your plan is. :(

Re: Pic: Team 935's nearly complete chassis
 

How much does it weigh?

Re: Pic: Team 935's nearly complete chassis
 

Thanks for the replies. Our chassis is 7/8" off of the ground and our CIM are 9/16" off the ground. I am not sure who was logged on to our railerobotics account but the statement about it being 1/4" off the ground is incorrect. Even with 9/16" we're cutting it close. Some how our team missed that part of the rules so I really appreciate the feed back.

We have not yet weighed the frame. I'll report back when we do.

Re: Pic: Team 935's nearly complete chassis
 

#25 chains and no tensioners? How does that work?

Re: Pic: Team 935's nearly complete chassis
 

That's incredible. How was the machining done??? Looks like CNC possibly???

Re: Pic: Team 935's nearly complete chassis
 

That is pretty cool. We might try Mech. wheels this year, but who knows. that is awesome. how'd u make it so fast?

Re: Pic: Team 935's nearly complete chassis
 

In 05, when 190 did mecanum, the chain was short enough (as it appears in these photos) to not need tensioners.

I still worry about the lack of articulation to keep your wheels on the ground. If you lose contact with one wheel (which seems likely with all of the high CoGs we're going to see), you lose control.
Unless you have suspensions I don't see, I'd watch out for control issues emanating from the lack of contact.

Re: Pic: Team 935's nearly complete chassis
 

This is a veery beautiful chassis. Only concern is the same as everyone else's it may be too low. otherwise it looks pro!

Re: Pic: Team 935's nearly complete chassis
 

Looks awesome, good luck during the season.

Re: Pic: Team 935's nearly complete chassis
 

one question... is that legal? o_O

Re: Pic: Team 935's nearly complete chassis
 

It does not seem to break the rules. Why would it be illegal?

Re: Pic: Team 935's nearly complete chassis
 

it just seems to big to be legal, maybe they made the chassis to the maximum it could be?

i dont know, it just seems to big

Re: Pic: Team 935's nearly complete chassis
 

That is primarily an illusion. This robot happens to be a chassis of the "wide" aspect ratio (38" dimension in the front), while most robots you see are of the "long" aspect ratio (38" dimension on the side). Wide aspect ratio robots strike me as an odd choice this year, but to each his own.

Re: Pic: Team 935's nearly complete chassis
 

First, we have not yet installed the chain tensioners. It actually drives very smooth without them but we are going to add them.

We used mecanum wheels last year with a similar chassis. We never had control issues so we never added suspension. It seems to drive extremely well without it.

The robot was done on a CNC machine.

And like lukevanoort stated we are very close to max dimensions and decided to make the wider longer than it is wide. Since there was a rule that stated that you could reach more than 80 in we decided on this to give us a little more reach.

Thanks for all the replies and feedback.

Re: Pic: Team 935's nearly complete chassis
 

I'm curious about your reference to a rule "that stated that you could reach more than 80 in".

Could you provide a reference from the manual? The 80 in horizontal distance limit still applies

Re: Pic: Team 935's nearly complete chassis
 

Looks great. I am drooling

Do I see grips by the wheels so that you can pick it up? Good ideal. Good luck

Re: Pic: Team 935's nearly complete chassis
 

The only thing I find illegal about that chassis is that it's too nice. You guys did an AWESOME job. I am also curious about manufacturing though. Waterjet perhaps? I don't know if you will have the time, weight, or desire to do so, but I think if you powdercoated it to be your team colors, you would hear people's jaws drop as they see it. Sweeeeeeeet chassis.:D

Re: Pic: Team 935's nearly complete chassis
 

I've found that sometimes people forget the negation. However, last year's (80") rule was interpreted in such a way as to allow extra length. But, last year's rules do not apply! If you reach more than 80", then you have broken the rule. (I'm working on avoiding that too-long robot.)

Re: Pic: Team 935's nearly complete chassis
 

it looks like you mounted a laser ot your bot due to the way the light is :cool:

Re: Pic: Team 935's nearly complete chassis
 

Is it just me, or is there no gear box? Or is yours really small and nice? xD

Re: Pic: Team 935's nearly complete chassis
 

You are correct in that there are no gearboxes. The ratio on our sprokets and the use of CIMS allows for great control. This is especially true with this year game. If time allows we would like to Yellow dip the chassis.
As regards the ablity to reach higher than 80" we will see. We may have to limit that movement:D

Re: Pic: Team 935's nearly complete chassis
 

With a wide robot, the front bumper will be closer to the middle of that mythical 80" cylinder than with a long robot. This would allow for a longer reach of the arm to snag in the ball. I haven't drawn it out to figure exactly, but I think it would be in the neighborhood of 1/2 the difference between length and width - so maybe 5"?

Re: Pic: Team 935's nearly complete chassis
 

HELLOOOoo from the North East
Looks great is that in the 120 lb. class ?????? see you soon
MOE and Team 88 TJ2:D

Re: Pic: Team 935's nearly complete chassis
 

stop spamming every thread

Re: Pic: Team 935's nearly complete chassis
 

I do have to point out the main fuel for getting the bot done so fast is in the background Sitting on the bench. lol:) Great Chassis Guys

Re: Pic: Team 935's nearly complete chassis
 

Just one question, I'm not sure if this has been answered before.... but what are the dimensions?

Re: Pic: Team 935's nearly complete chassis
 

The Dimensions are approximately 37 inches by 26.5 inches

Re: Pic: Team 935's nearly complete chassis
 

that frame, just blows my mind away.

Re: Pic: Team 935's nearly complete chassis
 

That is one very nice piece of design and construction. I am jealous. Best of luck in the game, I hope I get a chance to see that machine in action.

Also, that's a really well-composed photo, with the sunlight on the lockers and the vice visible - maybe by accident, but nice nevertheless.

Re: Pic: Team 935's nearly complete chassis
 

I would like to say that your robot looks amazing! The only problem I see is the accessibility of the main breaker. It seems to be blocked by the battery and with any type of mechanism on the bot it might well be very hard to reach.

Re: Pic: Team 935's nearly complete chassis
 

That is a small robot.:rolleyes:

Re: Pic: Team 935's nearly complete chassis
 

If your referring to the electronics board I would like to let you know that the board that is there is just a test board. Our electronics will be quite a bit more organized on the board we use for competition. When I find a pic of last years electronics board I'll post it.

Re: Pic: Team 935's nearly complete chassis
 

That is quite possibly the sexiest frame I have ever seen :eek:

Re: Pic: Team 935's nearly complete chassis
 

That frame looks really cool. Good Job guys.
