I recommend polycarbonate. Any mechanism extending out of our bumpers (within volume constraints of course) are polycarbonate. Polycarbonate rarely cracks or breaks on impact in standard conditions. The only time we have ever cracked polycarbonate was in 2015 with our polycarbonate tote intake. The only reason we thought it shattered on impact was because loctite was used on the screws that attached our motors to the polycarb plate. We think that the loctite reacted with the polycarbonate during its assembly and made it brittle instead of flexible, and that's just our hypothesis. The only areas where there was evidence of shattering was in our motor mount holes. After avoiding loctite on the rebuilt intake, it never experienced any cracking after several more regional and championship matches.

Our lesson was to be careful of what possible reactive chemicals come in contact with polycarbonate. And DON'T use acrylic. That's guaranteed to shatter.
