Acrylic is not allowed but I thought 1714 always used Polycarb.

Ah nevermind then. I retract my previous statement.

Incorrect. Acrylic is allowed, provided you don't go over cost and weight constraints and all those other general rules. However, using it on a robot? Not if it can be avoided; it breaks too darn easily on impact.
BTW, there's a robot in that picture? I only see a bunch of wires and other miscellaneous parts... ![]() |

Re: pic: Team 1714's 2011 Robot
That is so hard to believe! I am surprised that it weighs that much...Rough stats gives the weight of unfilled polycarbonate at 0.043 pounds per cubic inch and the weight of comparative aluminum 6061 at .098 pounds per cubic inch. I'm sure you pushed the envelope, just would really love to hear where most of that weight went ![]() Nice work, Like the design! |

Re: pic: Team 1714's 2011 Robot
It looks great, and I can only assume that with "continuous improvement" it will be even more beastly when I get to see it in person. I was really excited to see that you guys decided to return to Minnesota. Great team, great robots, enough said.

What robot? I don't see a robot! *squints* Ohhhhh...
It's nearly invisible! |

Re: pic: Team 1714's 2011 Robot
Polycarbonate (Lexan) weighs about half as much as the same size piece of aluminum. However, it is not nearly as stiff. To achieve a similar stiffness (which is necessary in things like arms, chassis, etc.) you're going to end up at around the same weight as if you did it with aluminum, maybe even a little heavier. The weight in this robot probably went towards making it stiff enough for the rigors of competition (drivetrains that flex are not fun).

Also, Thanks Nuttyman54 and AdamHeard. Sure it could weigh the same as aluminum if it has increased the thickness, but from the picture, I had trouble noticing any difference in thickness considering it's practically invisible ![]() |
