victor changes?
 

we have had some things not working out with speed controllers and was wondering if there was any difference from this year's victor controllers and victor controllers from previous years?

thanks much

Re: victor changes?
 

yes there is... they are different models... this year is a victor 884 however in previous years we've used victor 883.
so... what are your problems...

Re: victor changes?
 

well, we had a jag blow on us and we are having a hard time getting everything to work properly.

Re: victor changes?
 

2007 and 2008 were also Victor 884's. Can't say about years before that.

Re: victor changes?
 

well we have always used 883

these might help you...

looking at them the most likely problem may have been wiring since that seems to be one of the best ways when it comes to wrecking a victor so id suggest looking at the wiring guidelines section for the victors since it does list at the end several things you shouldn't do. For jaguar there isn't much on the manual about faults however on the first page there are 3 warnings of things you shouldn't do.

In which case, you've been illegal for some years, unless you're mistaken about which number was on the Victors. I'm guessing the latter, or else the inspectors didn't know the rules.

884s have been the only legal Victors since at least 2006 (the last year for which a full manual is available--see http://www2.usfirst.org/2006comp/Man...obot_Rev_F.pdf, <R27>).

I personally remember the 883s being illegal since 2004 at least.

well normally i don't work with the robot build much so i could easily be mistaken which we are using. ill have to go check with them.

Re: victor changes?
 

EricH is correct. 2003 was the transition year from Vic883s to Vic884s. 884s came in the kit, but you were allowed to use 883s if you had them, much like this year where you're allowed to use Jags and 884s.

However, there are quite a few differences between Jags and 884s. 884s have an update frequency of about 100Hz, while Jags have an update frequency of about 200Hz. Jags are also quite a bit more linear than 884s.

The code differences should be as easy as changing:

Jaguar *motor;

motor = new Jaguar(1);

to:

Victor *motor;

motor = new Victor(1);

in C++, or in LabVIEW, just replacing the Open Jaguar vi, with an Open Victor vi.
