Re: 1.1 Pump (am-3227) Really an improvement?

Is the inlet air filtered at all? The Viar has a filter built into the end cap, but this one seems to just be an open hole to the pump.

We had some failures from a different pump last year, and we...

Re: MI is the best?

You made quite a leap there. I don't see anything in this thread so far that even hints at what you're suggesting. Robot performance and STEM inspiration are not mutually exclusive. In fact, I'd...

Re: pic: Team 16, The Bomb Squad's Climb

I'm not sure what you're asking. The bumpers are clearly above the low goal.

Re: pic: Team 16, The Bomb Squad's Climb

Two big honkin cylinders and a couple of constant force springs. This (https://www.youtube.com/watch?v=rv6ppiBgWCA) is the match the pic is from. The rest of the regional is on Breakaway's YouTube...

Agreed. Those two boulders would have given us the capture.

Re: navX MXP without PID control

I've not had good luck with very basic control methods like you've described, usually because of overshoot. I've found the D parameter to be necessary to slow the rotation as your robot picks up...

Re: 1678 Two Ball Auto

Wow. Thanks guys. Now I have to listen to Brandon ask why we aren't doing this.

For real though, this is just awesome. Looking forward to seeing y'all compete.

Great job and good luck!

Re: Bomb Squad 2016 - Black Widow

TMW2012 did score a few boulders early in the season. :)

Re: Bomb Squad 2016 - Black Widow

Come to think of it, there's no sugical tubing on it anywhere. I can't remember the last Bomb Squad robot without sugical tubing.

We may have to find a place for some before inspection next week...

Re: Bomb Squad 2016 - Black Widow

It doesn't back drive. Horizontal to the floor gets the scale. Going all the way up puts less stress on the cylinder rods and clears out the bumber zone for the climber me next to us. We also think...
