Glenn, I think you're grossly oversimplifying the Q&A response you're alluding to.

There's miles of difference between "one particular implementation of 1/8-inch plate on standoffs may not be allowed" and "nothing made of 1/8-inch aluminum will be allowed".

So who constructed your chassis, Motorola?

What is this supposed to mean?

[Tom Line]

I believe he's asking where/what facility the beautiful machining work was done.

[spc295]

Harris & Bruno Intl. is the sponsor/machine shop that helped our team through the CACT program.

[spc295]

so we are awaitng the GDCs ruling, we have submitted our question, regaurding our chassis legality

[waialua359]

Hope they provide an answer and accept it as a legal chassis.

After a lot of articulation and debates, our team already started working on a solid rectangular tube backing today with provisions to remove easily.
Thus, our cantilevered wheels will be easy access for repair/replacement.

[spc295]

as of the last team update I believe that our chassis will be legal, just in case we will have some new plates milled from a metric sheet we have, that is like just a little more then 1/8th. because it will be the same as 1/8, but its not.

also now that we have both of our twins driving it is really interesting how well they drive with trailers, our tank drive is long but the front wheals do not stick out as far as the back, which really improves our turning. we were drifting and everything. I am not sure why but it drives much better then the 2007 robot on regolith. but I think it has to do with the differnce in axle lenghtes from front to back

[spc295]

from the gdc last answer i think we are in the clear

[Jared Russell]

I'm not sure why any rulings on bumper backings were ever necessary on the GDC's part. They made it abundantly clear that there would be high-speed collisions this season. A damaged frame seems to be a fair price for not heeding their warning.

And I agree with the posters here that the frame pictured should be able to withstand anything another robot can throw at it this year.

Cool chassis, i don't want to get this thread locked but it would have been cool if the chassis had been built by the kids not just drawn by them.

If everyone bought a chassis, FIRST wouldn't be the same.

Have you watched kickoff?
Dave made it pretty clear on the importance of having mentors.
I also dont think its clear cut and dry on who does the work for any team.
I'm sure teams in general try to incorporate as much student ownership as possible.

Don't you think the wise decision would then be to not make that comment in THIS thread and either PM the person you are directing your comment at, or start a new thread to talk about that specific topic??


Anyways,
Love the chassis 295...they look really nice

A friendly reminder from the CD moderator crew:

Confine discussion in this thread to the topic at hand-295's frame. Not who built 295's frame, or whether it's good or bad that it was done that way.

If you wish to address that topic, search the forums for other threads which exist for that purpose.

Plus this is an exact representation of industry. Many companies do not have the machinery to fabricate many of their products, and as such, the company must contract out to a fab shop to have their parts created. We do the exact same thing and I don't see how having a shop laser cut parts that the students design that could not be manufactured any other way is against the beliefs of FIRST. The purpose of FIRST is to inspire students to go into science and engineering fields and having someone fabricate parts in no way diminishes this aspect.
