If I were you I'd take advantage of this compact design and rewire everything and cut all the wires shorter.

I thought short circuits were bad for robots??

Tytus, if you dont clean that up, I will have to come over and fix it.

He means short wire lengths - i.e. less distance and wire in between terminals.

Make sure there's some breathing room, you dont any victors burning up, and ya, if you need to have it cleaned up, i'll drive all the way from Melbourne Florida to clean it.

Don's trying to be funny (I think) (aka short circuit= BOOM!!!-). I like the idea, but shorter wires would definitely be a good idea. Other than that, me like!

I have to say, it seems like a bad plan to me, there's no reason for that kind of wire length and closing the system up like that makes it difficult to work with the lower levels, as far as I can see anyways. Also, it just seems like asking for trouble to leave Victors cramped in like that, in that rats nest of wires, with little ventilation. Also I shudder to think what kind of electrical noise is being rained on the PWM cables you're going to have to install.

Honestly, and no offense, this doesn't seem all that impressive, or even all that compact, or modular given the high probability of tangles.

The object of this design wasn't to make the electronics very neat or pretty looking, or even accessible. The idea was just to save space.

It's not just a matter of looking bad, it's risky, and ineffective and could cause all kinds of problems later on, all of that traded off for what isn't really much of a space savings compared to most teams set ups (again, as far as I can tell) seems like a terrible idea.

I'm sorry if I seem rude, but I just don't think this is a very effective solution.

I agree. I dont care how nice and expensive your parts are.. If you blow a Victor in finals, you're done.

see you guys on the field

[JamesBrown]

A couple of questions,
What are you using to attach it to the motors/solenoids/every thing else?

What are the dimensions?

Also if there is any concerns about over heating why not just put a muffin fan or two on it, other teams have done modular designs and have not had trouble with their victors.

[Lil' Lavery]

Most other modular designs have typically been easy to access the victors (or had spare ones built right in). 116 is currently building our 4th iteration of modular controls, and all of ours have been far easier to access the speed controllers and relays than this one appears to be. 1889's control system is easier to access the RC than ours is though, and appears to be more compact.
Also, how can you see the status lights on the victors? Or do you plan to troubleshoot any errors that occur without them?

Don't sweat these haters, Tytus - Those Victors are bulletproof. Has anyone here actually burned up a correctly hooked up Victor without resorting to metal shavings?

But seriously, have you ever heard of zip ties? Also, the spaghetti store called, your tab is coming due. I KEED I KEED. And in conclusion, this:



This was on our very sucessful 2005 bot, and was only really scary once, in Denver, when we had to troubleshoot it. On the field. This year's will be a little bit better.

Yes, I have. Twice. They do overheat, it matters. My post was not a slam, it was a fair and honest critique of the design. Victors are not bulletproof and I would never risk a $115 piece of equipment on "I've never seen this happen before".
