Thanks

Allison

If you check the bottom of the page below the CAD files you can note that the two stage package is 2.50 lbs., and the three stage gearbox is 3.05 lbs.

JVN can clarify, but I would assume those weights are fully dressed with the mounting bracket and the pneumatic cylinder.

Congratulations to everyone at IFI, the entire product line is simply amazing, I already have a long shopping list. Christmas came early this year!

The VEXpro line may just cause more traffic here on CD, than a 2013 FRC game hint!

Interesting phenomenon we're seeing...
We've had a few VEXpro Ball Shifter sales, and most of these orders include a pneumatic pancake cylinder, and encoder mounts.

These are included.
Every ball shifter includes the pneumatic cylinder, all the hardware to mount it, and all the hardware for encoder mounting.

I've asked out web-team to try to be more clear on the product page.

I've thoroughly read all the product pages along with a few other team members, and for the items like the ballshifters, it is a bit confusing during the first read. A lot of the items could be a bit more clearly displayed probably. If myself and other experienced members need a double take to figure out what's going on, I'm sure the casual team will be confused by the pages.

Can you post the dimensions of the VersaHub? Definitely looks like something we'll be using in the near future.

I agree. A close read reveals that the pneumatic and encoder hardware kits are included with the shifter. Those items should probably have "(included with the base kit)" or something similar added to the description.

I hope if you order the optional gear kit along with the 3-stage shifter you get both the 60:24 and 64:20 gear sets - because that's what I did and that's what I wanted...

Yes, you will be getting both gear sets.

Can one of you comment on how much assembly is required for the ball shifter upon receipt of it?

EDIT: BTW, I noticed that product 217-2712 was not listed in the "Specifications" section of this page: http://www.vexrobotics.com/vexpro/ge...pro-gears.html

Bumping this question. I know many teams opt to use their own nitrile tread, whether its for functionality or aesthetics.

THANKS for this awesome resource! I have tears of joy in my eyes....
Students - let this be a lesson in business applications of engineering - Both VEX (IFI) and AndyMark are fantastic companies serving an exploding market. Your challenge is to figure out what is next and build your own excellent company.

Brandon,

The main ball shift shaft, which contains the two ball shift gears, shift engagement balls, retaining ring, and shifting axle is all preassembled. The customer has to assemble the cluster shaft and two gears on the cluster shaft, insert the ball shift shaft with 2 bearings, and assemble the housings and motors. Additionally, the user has to assemble the 2 standoffs for the shifer and the pneumatic cylinder. If the user wants to use encoders, then that hardware must be assembled too.

The user does not have to deal with the ball shift mechanism as that will be pre-assembled.

Paul,

Would it be possible to buy just the shifter shaft and all the associated hardware without the two gears? We would love to do the ball shifting but would prefer different gear ratios and would just machine our own gears most likely from your other gear options.

I have a simple question, only necessary because our computer lab is closed and I don't have any CAD software on my classroom PC... (Not for lack of trying, mind...):

How wide are the mecanum wheels with/without hubs on them? We're in the process of upgrading our octocanum drive platform and are wondering how much redesign would be necessary for these wheels/hubs.

Thanks!

Hi Patrick,
We're going to be posting individual part drawings with key dimensions in the coming weeks (we posted the STEP files to help people get started).

The Mecanum wheels are both about 2.3" wide. The widest point is roller-roller.

Are the screws for the VersaHubs included the the purchase? Or do we have to buy those separately?

The mounting hardware is not included with the hub.
