Well, if it makes you feel any better, we don't have all that fancy-smancy vex stuff, so ours looks gargantuan compared to yours.

Just like all the roller claws "identical" to 1114's last year, right?

Aww. I'm sure this will be the coolest looking follower wheel I'll see all year, "identical" in function isn't really identical. Last year we were "identical" in function to 987, but they were clearly better (in design, looks and performance).

Aww. lame. Sometimes we can blinded by awesomeness.

Have you tested to see what percentage of your total robot traction the follower wheel represents? (like the GDC posted)

I am not saying that I think this will represent >5% of robot traction, I would be surprised if it did. I am only curious because my team has yet to test our Way-Better, Uber-Awesome follower wheel we build out of Joe's spare Vex parts

John,

Are you running any sort of bushing on the vex shaft? Or, are you just letting it ride on the 1/8" hole in the ABS? (I'm having a hard time finding a flanged bushing for an 1/8" shaft)

Very pretty, thanks!

I bet they are just letting it ride in the hole. In the VEX system the bearings are just delrin with round holes so this plate essentially is the same thing.

[Rickertsen2]

I like it! Let us know what the accuracy of this turns out to be. A measuring wheel is something i always wanted to try. I'm assuming the remaining two holes are a pivot for this thing hang off of.

Just a word of warning about those greyhill encoders, they are very fragile and if subjected to remotely harsh conditions have a tendency to "go crunchy". Have a spare on hand.

We're just running it in the ABS. VEX shaft is designed as a "rounded" square profile so it works great in that application.

Every time I see a teaser/picture from 148 I feel like a tiny kitten who is lost in wonderment and amazement of the string spinning from the fan. I spend about 30 minutes pawing at the screen saying "I can haz?"
