Re: Questions about operation of pneumatic valves
Thanks for all the replies! This is an issue that has just recently appeared, so it could very well be a wiring issue, but now that we know it's safe to keep the solenoids powered, we'll try that as...

Questions about operation of pneumatic valves
We are using the standard SMC double solenoid valve sold by VexPro.
We are controlling it using the WPILib DoubleSolenoid Java class.
We are using the controlled piston to hold a latch in place for...

Re: Registration 2017
Or... perhaps they will learn that when you have a "mission critical" system (which I would argue is true in this case, with the large number of professional man-hours being wasted due to its...

Re: Did FRC3548 become DNP at MSC due to red card!
<Bolded for emphasis>
I totally disagree with this approach. Yeah, too bad you are tipped and can't score, but you should have thought of that when you designed that top heavy robot to begin with....

Re: Banging the driver station
Yes - please tell that to all the refs who *inconsistently* handed out red cards last year (including one to my team's human player) for doing something relatively trivial involving the chute door. I...

Re: Banging the driver station
But most teams have all wheels on a side driven by the same axle either via chains or belts, right? So unless you have independently-driven wheels (with an encoder on only one of them) or unless you...

Re: Banging the driver station
Thank you for the detailed explanation. I feel your pain on the flaky Dashboard readings. We too were struck with this bug in Week One - several times the autonomous just didn't run at all, even...

Re: Banging the driver station
If you are low-bar capable, one thing you could do is always ask your alliance partners if you can have the low bar spot - it never hurts to ask. And if one of them has a low-bar autonomous that does...

How many teams have actually practiced going under the Low Bar WITH the...

Re: REV Sparks or Vex Victor 888?
OK - thanks. I forgot about that feature. But in my defense, it's still CAN that makes it all possible. :p ;)
As a mentor whose teams have used CAN beginning way back in 2009 when the Jags first...

Yes - if all you care about is the overall current draw on the system, the built-in CAN in the Roborio and the PDP is all you need. I was simply pointing out that having intelligence about each...

Re: REV Sparks or Vex Victor 888?
In 2015, 3467 also went whole hog with the Talon SRX - we used one running the built-in Speed Control mode for each of our four mecanum wheels, and two (1 master, one slave) for driving our elevator...

Re: Airplanes. Airplanes everywhere!
Let's see - they kick everyone out of the pits at 5:30 sharp, and then rather than starting the ceremony on time at 6:00, the actual starting time gets dragged out till almost 6:30.
