Another electical setup idea from my team fo 08...

[tseres]

i like it, but personally i'd rather make it a little bigger and have the victors on the inside of the lexan to be more protected

Given the options of putting some further protection around the box as pictured or moving everything inside (and then risking a close-quarters Victor surgery), I'll put some more protection around the outside.

My question deals more with material choices. I can't tell thicknesses of the materials, but was there any reason to choose them? Cost? Availability? More strength to tie into some other part of the robot?

Like the above have said, my biggest worries is about the protection. Also with the previous model you showed us there was some modularity which meant you could remove parts and add them easily. With this it seems like it will be a bit harder. Also are your students considering weight? Weight is a BIG deal. Also what size have your previous years' bases been? For an average team, that idea should be okay, especially if you're using some sort of 6 wheel or tank drive. Good luck and I hope to be seeing more from your team!

we were talking about using 1/8in polycarbonate with 1/4X1/4X3" aluminum pillars, everything will have tapped holes so all we would do is just screw into it, same with the victors so if we blow one its easily removable, me and the other mentors decided thats basically what we wanted to go with, but we were up to what ever idea the students came up with. the main reason for this was because we have all these just sitting around

I like this exercise, it gets the students thinking and working with inventor.
I'd lean more towards total space savings and not worrying about victor repair.
As long as I've been on 190, and quite a few years before that, we've never had a problem with our victors.
The problem with an electrical box of this type is that often there simply isn't room in the robot to have everything electrical (and pneumatic in this case) centralized. The current design (which is well done and a great thing to do if possible) requires a significant amount of space on the robot, and space is the second most precious commodity on a FIRST robot.
The first most precious commodity is weight, and we've found that unless your robot has several pneumatic cylinders firing often during the match, 4 accumulators is far more than necessary. Our robot this year, which had the two major systems pneumatically actuated, got away with a compressor and 2 accumulators.
All in all, excellent way to get the students involved, keep thinking.

On an unrelated note: If you can afford it (and find them), I highly recommend using nylon bolts for mounting electronics. The bolts are just fasteners, and weight is always at a premium. We used them with great success this past year.

wow I really like that idea of having the reservoirs under all of the electronics.

Protecting the victors from having little bits of metal fall into them and short them out is important, but so is protecting the RC. During build last year (or was it two years ago, now... I forget) we had a small aluminum chip fall onto the RC and land in such a way that it shorted out a couple of unattached I/O pins on the RC. This led to all sorts of RC weirdness... thankfully no permanent damage... but since then I've figured that having a lid over everything is a big asset.

This is a great exercise, though... I might have to set a few of my students loose on a similar project just to get them thinking and practicing on inventor.

P.S. Yeah, I know... never drill or cut over the electronics... but those little chips get everywhere.

[cdennisxlx2]

we rarely have problems with chips, and almost never have any problems with victors tho we were throwing around the idea of a screen covering for the victors

veeerrrry swanky i like it- we tried making a removable panel last year and that my friends, is the making of a purely superb modular design (i hope by anderson power-pole you mean mini andersons- which was some thing I've stumbled across over the summer)

CHEERS!
