Team 1538 finished all the sprockets for their robot this evening.
It's just too bad AndyMark doesn't sell an aluminum 160 Series, 15 tooth sprocket with a 4.5" bore and a 1.25" keyway...
Oh well, guess we'll have to make them ourself out of steel...

Jamie KalbHOLY COW!
I was about to say, "What on Earth are you doing with all those little sprockets," when I saw the BIG one. I'm putting your robot on my "Can't Wait To See" list right now.

Chris is meYou can't be serious. That sprocket would weigh dozens of pounds....
I'm carefully noting the rest of your sprockets though. Though I wonder what it tells us that we don't already know (swerve drive).

Chris is correct, the 160 weighs dozens of pounds... However the 45 tooth version (not pictured) is even more impressive...

Stuart. . . ok my mind is melting . .
is that 1 really big sprocket with several normal sprockets around it . . or one normal sprocket with several baby sprockets . . its like some sort of surrealists take on engineering.
either way super cool baby/jumbo sprocket(s)

sanddragHmm, about 40 of them. Either that's a lot of spares, or a lot of wheels.

rsiskHey Jon, are you making some sort of planetary gear system?
06-02-2010 08:21
Dkt01You should use that big gear as a decoration. Or is it just extra weight. No matter what, you piqued my curiosity.
