Are there always stack bins in Choice? I believe that boxes were used as the 2003 game piece...

Re: FIRST Choice 2015 Window Open
 

the boxes in 2003 were rubbermaid tubs. If you're suggesting these can be a game piece... we're all doomed.


I noticed that the two belt sizes used in last years kitbot are available in limited quantities. Maybe that indicates that this years kitbot will not be using the same center to center distances? larger wheels maybe? an obstacle maybe? frame perimeter change? hm?

Not horribly useful unless you're doing heavy simulations for your robot, but anyone else think the Quadro K4000 for 100 points is a steal? I mean come on, that's a $700 beast of a graphics card that costs the same as 10 mini dry erase boards. http://firstchoicebyandymark.com/fc15-114

Re: FIRST Choice 2015 Window Open
 

Maybe this is baseless speculation, but the stack bins are the only item I noticed that don't have a "yes" or "no" in the "In kickoff kit" box, therefore leaving the box blank. A hint perhaps?

Re: FIRST Choice 2015 Window Open
 

Much more likely, a simple oversight.

These bins are on a completely different scale than the 2003 bins

The item page says that these will be included in the kitbot box on kickoff.

Could someone please explain the difference between the two Jags?

Re: FIRST Choice 2015 Window Open
 

I wish they told us the resolution on the CUI encoder there...AMT103-V isn't exactly useful. I could be missing it, but I don't see it anywhere.

Re: FIRST Choice 2015 Window Open
 

It says it's programmable. Here's the Digikey page for it, http://www.digikey.com/product-detai...1308-ND/827016 and datasheet http://www.cui.com/product/resource/amt10-v.pdf

Re: FIRST Choice 2015 Window Open
 

Thanks, I thought I was going crazy. I've never heard of a programmable resolution encoder before. Now I'm going to have to research these.

Re: FIRST Choice 2015 Window Open
 

Note that ALL First Choice items are donated, but in quantities smaller than necessary to give some to each team. Although FIRST would just love to have more offerings (ask Kate Pilotte yourself!) in the donation world, you get what you get and love it. There are no game hints in there.

THANK YOU to all the companies who donated items. This is all very much appreciated.:D

Nominally they are the same, but the supplier is different. One could argue the ones supplied by Texas Instruments are older and so somehow inferior, since the later ones have (IIRC) some minor improvements, but in my opinion they are the same.

Re: FIRST Choice 2015 Window Open
 

The resolution is set by internal dip switches.

Re: FIRST Choice 2015 Window Open
 

These ones are the older ones (2012 season and previous) and earlier made by TI. These ones are the newer ones (2013 season - 2014 season) made by IFI. As far as I'm aware, they're identical electrically, but the ones made by IFI are conformal coated, while the ones made by TI are not.

Re: FIRST Choice 2015 Window Open
 

I get that, but I'm more curious in how they physically/electronically work.

Re: FIRST Choice 2015 Window Open
 

So it's probably reading position as an analog value (the capacitance), and then converting to digital. The dip switches just set the resolution at which you convert (just a scalar).

This is pretty common with magenetic encoders too (selectable resolution).

Re: FIRST Choice 2015 Window Open
 

That makes sense. Thanks
