They in fact use plexiglass. Having played hockey and seen the stuff shatter, it REALLY shatters everywhere. Video evidence:

As for how they "get away with it", my guess would be a difference in yield strengths. It may take much more force to shatter the plexiglass rather than bend the polycarbonate. I don't know this for sure, but that's how I could rationalize this application. That being said, polycarbonate is better than plexiglass for robotics because plexiglass will shatter like in above video.

based on the second and third incidents from this video (apparently from the same game), it seems to be laminated, at least in some venues, so that it doesn't send shards of plastic everywhere when it does shatter.

It's also that breaking the glass looks really cool and earns them higher ratings, so they want to do it.

it was also in the same period...

must have been on a hot streak.

as for why, lexan costs a lot more than plexiglass... and glass and perhaps even plexiglass is much more scratch resistant... lexan is a softer material and is more scratch prone. given the amount of contact the panels see, it wouldn't take long for dust scratches to ruin the panels...

Just a word of caution, Plexiglass is acrylic, which shatters on impact; The palates had polycarbonate, which doesn't shatter under normal conditions and bends to absorb impacts rather than failing completely. I don't recommend using plexiglass on or near the robots for anything, but polycarbonate is a good material for FRC when it is properly used.

Sorry there, I mistakenly wrote the wrong material. Anyway, I believe everyone knows what I am talking about...;)

Are we sure we go everything out of this? Did we scrutinize it completely for every possible detail? Maybe we aren't getting something.

We've been doing this since about page 2.

that last post is a little over the top but the point is valid. That is the way these threads normally go though they are twice as long. :)

For the sake of entertainment, im rather happy that this is back on the top of the portal.

O.K so what is left to dissect on this hint that we haven't yet?
*crickets*
