I believe it was a collaboration between 254 and 968.

Acually in '03 they didn't have a shifting transmission design until the Cal Games comp seen here...

That design went into their '04 bot seen here.

'05 was further refined when they added FP's with AndyMark Planetaries...

'06 seemed similar to '05... pic here

There are some transmission designs in the white papers section - check them out. I remember looking at Andy Baker's design back in '03 and inspired us to make our own and it looked like this... It was so heavy and bulky we never actually used it in a competition bot. With the motors on it, it weighed in at 22 lbs.

Then we got inspired by Paul Copioli, Thunderchickens, and tried to make our own version of CVT (kinda) that looked like this.... That never worked as well as we hoped, but nonetheless the students learned A LOT by trying.

So do some research and start designing a transmission of your own. Even if you don't use it, you'll be ready to adapt to any new changes FIRST makes for the upcoming seasons.
