Sorry... I just have to.

Those middle wheels are not "plaction" wheels. They are IFI traction wheels. AndyMark sells the plaction wheel and are black plastic.

Yes they are!

I'll be honest.. fellas, the chassis is looking great. But.. I could've used a little more cowbell. The last time i checked we don't have a whole lot of robots that feature the cowbell.

agreed

It's a shame that you can't just put your bumpers on this year and call it a day. Looking at all the screw holes at bumper height i would imagine you guys are just going to add a flat piece of stock over them to expand your frame perimeter.

Interesting choice! Very facinating to see 1/4

Looks a bit on the heavy side, but should work great!

Re: pic: Team 935 Chassis Teaser
 

I am going to be a bit controversial and say that while the chassis is a work of art in many ways, I wouldn't trade it for the chassis that our team is building with little more than hand tools, standard C sections from McMaster and about 2 hours of mill time poking in a few critically placed (and large diameter) holes.

Every team has it's own strengths and weaknesses. Teams should play to their strengths but I fear that some teams use certain technologies on their robot mostly because they have access to it (e.g. a CNC mill) rather than because it it the best technology to use.

A contrarian view presented for your consideration. Please believe me that it is not intended to in a mean spirit and that no offense is intended.

I love this point of view, mostly because it is similar to my view on the matter. I have friends on other teams who love using their CNC equipment even when they probably don't need to to cut weight or make a part quickly/precisely. I also have friends on other teams who have amazing facilities, but limit themselves to what they actually want to get machined.
We are similar to the latter example. We have pretty great resources and fabrication available, but its usually just used for very crucial components that must be machined in a way we can't do on our manuals. During the design process, we also try to avoid heavy machining or CNCing parts while drawing the parts in CAD.
An example of our machining resources - http://kozakproducts.com/facilities.html http://www.gpsheetmetal.com/index.html

I may open a new thread for this type of discussion. Or, Dr. Joe, if you would like to start one I would be interested in reading what others have to say.

The frame you guys have looks really sick. I look forward to seeing how our mentored team 2395 does with/against you at OKC regional! :)

I really couldn't agree more. There's two sides to the view, for certain. On one hand it leans students to be more creative and flexible by working within the realms of the materials provided and does a great job of teaching them how to be resourceful in making components work with each other with what can sometimes be considered a minimalistic, but effective approach.

On the other hand, having an abundance of resources allows the students to broaden the scope of the project and be more creative by allowing them to design custom components from a clean sheet and use modern practices in creating their robot; both exposing them to the design aspect of engineering and the practical aspect of manufacturing (all though this is by no means the limit of the scope of FIRST).

I believe both are very valuable skills for students to learn, but it seems to be rare to have both under the same umbrella.

Our program certainly leans towards the latter of the two approaches I mentioned. It's certainly not a bad thing, but I admit I would like to see the students "squirm" and try to be more resourceful in meeting their goals. ;)

I think resourcefulness is a skill rarely taught in education after high school, but can often be more valuable than learning modern practices.
