Re: pic: FRC 2869 - 2016 Offseason bot

Had you considered putting a pneumatic spring on the intake/lift arm for stability, smoothness of operation, and reduced force necessary to lift it?

Re: New AndyMark Product Game Hint???

I wasn't aware of that.

Ah, well. Back to the speculation that I'm probably wrong.... :D

Re: What hath we wrought? 2016 Horror Stories

We shredded the aluminum gears in a pair of WCP/VexPro dog shifters--reduced the teeth down to nubs over the course of the Tech Valley regional; we had spares from our practice robot (that had been...

Re: Eliminating "Start Build Day"

We build them, so it's not about the money.



The thing I don't like is the never-ending time drain that FIRST has become since the withholding allowance became reality. Unless the thing I need to...

Re: Registration 2017

There were seventeen spots open for Buckeye at noon. We got one of them at noon + 2s, at which point there were four. Then none at noon + 13 s.

Finger Lakes was our first registration, but I checked...

Re: Eliminating "Start Build Day"

I'm approaching the point where I may have to step away from FIRST just because of the other demands on my life. (I do a lot more than just robotics).

Personally, I would like to see a hard step in...

Re: What's the gender demographic of your team leadership?

Right now with 22 students, 4 female, we have a 50/50 split on leadership roles.

In 2010, with 14 females and 14 males, we had 75% male leadership.

In 2013, with 19 students, 4 female, we had a...

Re: VersaDrop Stability

We used pneumatically-shifting octocanum for several years. It's big, it's clunky, it's heavy, it's expensive.

It also made for some awesome omnidirectional awesomeness and some fantastic defense...

Re: Most Effective Robot EVER?

Objectively I'd say 71 in 2002, but as my then-team 827 got totally owned by the 71 2001 robot, subjectively I'd say 71 2001. We latched onto a goal and then got dragged around for two minutes as if...

Re: Was the Low Bar worth it?

The only thing I would change about our robot is that I'd have pneumatic wheels on the drivetrain, and a better portcullis lift. (I couldn't find decent pneumatic wheels by the time we'd hammered...

Re: 2016 IRI Rule Change Suggestions

If I were in charge of making Stronghold a top-tier-robot-only game, I would:

Keep the tower strength at 10, as at Championship.

Keep all the defenses. (Heck, if we can design for the drawbridge,...

Re: Being Proactive About Paper Airplanes on Einstein

It's pretty appalling the condition that most people leave things, with the excuse that someone's going to have to clean it up anyway.

Re: Being Proactive About Paper Airplanes on Einstein

I disagree. It's *also* discourteous to leave soda bottles, food wrappers, [beer] cups, hot dog wrappers, and everything else for the cleaning staff (who will have enough to do regardless)--and if...

Re: Being Proactive About Paper Airplanes on Einstein

Ask:
1. Is what I'm doing to stave off boredom safe?
2. Is it courteous to others?
3. Will it not make a mess that others will have to clean up?

For paper airplanes thrown in a stadium, the answers...

Re: Security at St. Louis

I did research on a novel for places to not go, and for police corruption. East St. Louis topped the list on both.

Re: pic: Stripped VexPro gear

That's awesome, thanks!

(I'll probably still drill a bunch of holes in the steel, but will never go with aluminum gears in a drivetrain again.)

Re: Usign a 2-1/2 bore, 24" stroke pneumatic cylinder.

Yeah, yeah, yeah. Fingers before brain and all that.

60 psi working, not 120. :)
