Just be a little careful about how you structure your lexan/polycarbonate. 1/8" polycarbonate can do wonders... we build our entire robot out of polycarbonate every year.

Yes, polycarbonate is strong and light, but it can be flimsy in certain applications.

It makes an amazing electronics board, but using it in a drive train will take a little bit of planning. The easiest way to strengthen it is to bend the edges of your piece... It will still be bendable along the diagonals (if it's a square), but it will take a lot of flexability out of the center of the piece, which is what you need in a drive train.

If anyone needs any help in using polycarbonate, feel free to message me.

Good luck!

edit: After taking a second look, I see no one mentioned using polycarbonate in a drive train... oops... but I'll leave the information here anyway. Polycarbonate will be great for an electronics board.

These are generous with roughly 10% overestimation each:

Drive Train - 40 (precise)
Manipulator - 35
Pneumatics - 23
Electronics - 7
Powder Coating - 5

We're looking at just over 110lbs.

our robots weight is 75 lbs. total done and completed

Our drivetrain weighs around 50Lbs so we are in good shape.

lucky!

Right now we are 30 pounds + under without electronics.

I really don't know about our other parts, but our frame alone weighs 9 pounds, 1/8 aluminum (I think, possibly 1/16) Our claw is hopefully going to be composite, if we can get it to them within the week.

This is about all I can give for information as of now, I just transfered over to programming (of which I know none)

Hopefully if I remember I will post some spy shots of our super light frame within the week....assuming I remember.

Are teem's robot is some ware between 25 and 80 pounds ( chasy, electronics board, drive trane,…) We still have a bit to go but I think the heaviest part of are bot is finished.

[Dan Petrovic]

Our CAD model tells us 115...

It still doesn't have electronics, pneumatic tubing, wire, or chain....

[=Martin=Taylor=]

The estimate is 113 lbs. for the finished product.

Currently we are at 45 lbs. for drivetrain, electronics, and part-of-that-other-thing-which-I-won't-tell-you-about ()

105 with everything on it.
