There's no problem using 9mm pulleys in the drive, given you do the math, and take a look at what worked in the past. 971 ran 9mm, 24 (or so) GT2 pulleys with 3.5" diameter, 2" wide wheels and a traction limited low gear. As far as I know, they never had any issues ratcheting. There are plenty of other threads discussing this, but the horsepower ratings Gates gives are conservative for FRC applications.
According to the Google Doc that Adam Heard compiled, they had minor ratcheting issues.
If you use a LARGE pulley you can get away with 9mm, but there is very little penalty to stepping up to 15, and you will most certainly never ratchet if properly configured. Our design mandates smaller pulleys, so it's safer for us to go 15. Anyone with the guts (or foolishness :P) to do a belt-in-tube system should probably go 15mm.
If you go 9mm, use GT / GT2 pulleys. HTD won't cut it.
Joe,
What size pulley's have you ran?

We use 36 tooth, 2.256 pd... can't wait to see what AndyMark came up with for kitbot drive train.

Chris Is Me is right, we did have some ratcheting issues, but these only showed up in the post season.
We ended up replacing all of the belts before Madtown. They all failed by the teeth falling off, a sign of under tensioning. Thankfully they failed in a graceful way (robot still drove, just slightly reduced performance) and it was moderately easy to replace the belts.
We are still figuring out what we will do next year. We are considering widening the belts if we have space, increasing pulley diameters if we have space, or just running with the same set up again because it lasted for 3 competitions.

I was going over our potential order, and something ran across my mind,
Say I purchase a 3:1 ratio VersaPlanetary, and then realize that the 3:1 isn't enough of a drop. If I wanted the 10:1 ratio instead, can I just swap out the 3:1 gear sets for a 10:1 gear kit? Or will I have to use the 10:1 gearbox?
In theory, I ought to just be able to slap the 10:1 gear kit in there, but trying to be careful when ordering.

It's my understanding that the VersaPlanetaries are hot-swappable. The front and end pieces remain constant with your motor and output shaft options. Meanwhile, everything in between can be added/removed as you wish.
The VersaPlanetary is a beautiful system in my eyes. The ease of versatility isn't matched in the market.

Sunny,
You can absolutely just by the 10:1 gear kit. However, the 3:1 (and 4:1) gear boxes come with the 8mm CIM motor shaft. The 10:1 gear box comes with the 1/2" hex shaft. If you want the 10:1 and 1/2" hex, then you need to buy the 10:1 gear kit and the 1/2" hex shaft separately.
The gear kit is very easy to change by just removing the 2 #8 screws. The shaft is a little harder as you will need snap ring pliers to remove the shaft.

Think of it this way, at free speed the faster motor will try to drive the slower motor so the slower motor will act as a generator (a load) on the smaller motor. Don't worry, though, as soon as some load gets on the system, the lower power motor will slow down much faster and the speeds will be matched. Dr. Joe Johnson posted about this several years ago. I printed out that post and still have it for reference as he explains it much better than I explain it.
Could you point to this post? I'm having trouble finding it.
Thanks!

I'm impressed with the Vex Pro 2 speed shifter and was already to buy when I noticed the output shaft uses hex rod.
The reason for wanting a round 1/2" shaft with a 1/8" key way is because this shaft will match up with a very wide range of sprockets and pulleys. In particular I would like to try out the belts in the kit of parts and substitute your nice 2 speed for the default single speed transmission.
Only question is how can I make this work when my team doesn't own or have access to a lathe or a broach/press?
Paul, is Vex willing to build a few special order shafts for smaller teams without machining resources?
The Versa Wheels are shown as In Stock? Are they available now? Earlier there were manufacturing problems and they weren't available.

I received some VEXPro material today, from an order placed before kickoff. I'll be testing a fixed ratio gearbox and a Versaplanetary later on. Today we started working with the 7075 shaft stock and related components.
This stuff is really great! The first thing we worked with was some 1/2" hex shaft stock. Facing the ends we were impressed with how nicely it machines. It is noticeably harder than 6061, and this is apparent when cutting with a band saw, but facing the ends was not very different from facing 6061. The faced surfaces are beautiful.
As promised, the hex shafts slide nicely into bearings with no sticking or jamming. The collars are nice and small, fit properly, and feel very secure when tightened.
The hex shaft stock also fit into a hex hole that we broached in one of our standard steel poly-vee J-section pulleys using a duMONT 77713 that I purchased from McMaster-Carr (2875A24). The fit is a little tight, but we like it that way.
I will be using VEXPro shafts, bearings, and hardware (http://www.vexrobotics.com/vexpro/shafts-bearings-and-hardware/shaft-stock.html) for a project in the research lab at my day job -- and I suspect a lot of this same stuff will prove useful on my team's FRC robot as well.
Nicely done, VEXPro! :)

Edit: after posting I ordered a couple of gears (http://www.vexrobotics.com/vexpro/gears) for my day job project, and received notification that they have been shipped within 20 minutes of the order.
Freaky fast, kinda like McMaster, or Jimmy Johns. ;)

222 is extremely disappointed that we received our two 3 stage ball shifters with a paper in each box informing us that the third stage gears were not shipped with the transmission and that they will be delayed.
Since the 3 stage transmissions and gears show as in stock as of this post we would like to inform others who may have ordered this 3 stage ball shifter of the gear delay.
The team member who purchased the parts talked to IFI this morning and said that the gears should be in stock early next week. This means that we will (hopefully) have functional transmissions a week later than expected. While this may not affect our schedule too much it would have certainly been nice to know at the time of ordering rather than the time of delivery that certain required parts are not yet available.

While this may not affect our schedule too much it would have certainly been nice to know at the time of ordering rather than the time of delivery that certain required parts are not yet available.
This happened to us as well, but we ordered additional 34 and 50 tooth gears for the 3rd stage, so it didn't affect us much.
Additionally, it is worth checking to make sure your purchases will ship in a timely manner. I ordered QTY:10 of the 22T Hex Sprocket on Monday night, which was listed as "In Stock". When I didn't receive a shipping confirmation all day Tuesday, I called Wednesday morning to find out they wouldn't be in stock until Thursday or Friday. VEXpro then offered to ship them Wednesday if I was ok with not having the "VEXpro" logo and Tooth Count stamped on the sprockets. I quickly agreed to have them sent "as is".
I'm no warehouse management expert, but if "In Stock" is advertised on the website, it probably should be on your shelves. I completely understand having to process a ton of shipments, but not having the products available while listing as "In Stock" doesn't seem right.
Then again, I could be totally interpreting the situation wrong, but all I know is we won't get our sprockets until Monday :( [EDIT: While the initial estimated delivery date was Monday, it appears that our sprockets will be coming in today! Thanks!]
Also, I'm still waiting to hear back on our replacement Hex Bearings from IFI, one of ours didn't fit the 1/2" Hex output shaft. I had 16 similarly bad Hex Bearings from AM, and after I called yesterday they had 16 new bearings in the mail within an hour!
On a lighter note, we love our VEXpro Ball Shifters! And they come in such cool boxes! :D

Michael and Brad,
I apologize for your situation regarding the ball shifter gears and the sprockets. We 100% quality inspect all of our custom made components (we lot check commodity items like bearings) and we found the engraving issue with all of the 16T and 22T #25 sprockets. We shipped out some without engraving but sent the rest to be engraved and will have them Monday. They are currently marked as "ships early next week" so you can still order them. This was a timing issue and I apologize for any inconvenience this has caused.
We did have to ship a certain quantity of the 3 Stage Ball Shifters incomplete without the 2 third stage gears. Our rationale in shipping these incomplete was that we'd rather get the bulk of the shifter components out to customers and let them start assembling the gearboxes.
We have shipped out all of the missing gears for orders that shipped without them and the 3 Stage Ball Shifters are now shipping complete. Both Mike's and Brad's (well, someone else on your team) gears will arrive at the shipping address today. I have sent both of you the tracking numbers via PM.
For the stock situation, there are rare cases where our actual inventory and Web site stock status are not in sync, specifically when orders for larger quantities come in quickly. We agree that our customers need to know the actual status of items so they can have knowledge of when they will arrive. We move them to either "out of stock" or "ships in xx days" as soon as we are made aware of the stock status.
For the VEXpro components, I made the decision to not put an item "out of stock" on the web site if it was going to be made available in a week or less, but rather put "available in xx days" so you can still order it. If it is placed "out of stock", then you can't even order the component.
You'll notice that some sprockets and 2 of the VersaHubs are marked as 'Shipping Early Next Week' -allowing customers to place orders but informing them of the shipping delay.
With regards to the hex bearing, our customer support received an e-mail just before 4pm yesterday regarding the bearing issue. If your issue is critical, please call our customer support so we can address it immediately. We will send your bearing out today along with an RMA number and a shipping label to ship the bad bearing back to us.
Once again, we apologize for the issues you both had and appreciate the feedback. Please do not hesitate to contact our customer support directly. At VEX Robotics, customer support is our highest priority so if you are not satisfied with something please let us know.
Paul
I'd like to throw out that other than a interference fit between the gearbox shafts & gearbox bearings (0.002-ish), our parts have been really great. The 1/2" hex shaft and the piloting hex hubs are ridiculously nice for prototyping.

That seems like good service: the individual issue was acknowledged and corrected promptly, and then the underlying deficiency was addressed and apparently corrected as well.

Actually, it's probably better that you did, all things considered. It gave Paul an opportunity to address the problem promptly and openly, so as to set an example for future interactions with IFI. Assuming that no company can maintain a perfect record forever, the next best thing is for them to have evidence of successfully resolved problems out here on the Internet.
Besides, telling ChiefDelphi about the problem means that dozens of people who have a need to know, now know. If you hadn't spoken up, they would still be ignorant.

Received the Versa Planetary gearboxes yesterday that were ordered on Kickoff day. They look nice. One thing that's no big deal but I figured I'd mention is that in the future perhaps a tumbling or chamfering process needs to be added to some parts. Some edges are rather sharp. One slight difficulty I had was removing the little slotted steel motor adapter bushing once installed, if I decide to use a different one (or none). Is there a good method for this?
Paul Copioli
12-01-2013, 12:13
The bushings are a tight fit in order to guarantee a good clamp and good concentricity when the ring compresses. The easiest way to get them out is to use the motor they are designed for and put a slight side load when pulling out. This worked for me when doing testing.
Noted about the sharp corners. In some cases the manufacturer did not follow our print regarding breaking edges. We will improve this on future items.
Thanks,
Paul

We assembled the VEXpro 3 stage Ball shifters today.
This post is to alert IFI and other teams of an issue with the assembly of the 3 stage transmission only.
Both of our transmissions had this issue and it took some investigation to find the exact issue.
There is a gap between the stamped metal plate that houses the third stage bearing and the 1/2" hex standoff's. If you install the plate it will bend and cause other problems. It appears that hex molded into the transmission housing is approximately .05" too deep as the 3D model measures .25" and the actual measurement of the molded housing is .30". One fix would be to add shims between the 1/2" hex and the metal plate.

This problem has been taken care of. VEX is awesome to work with as always. Paul called and cleared everything up and they are doing more than what was required to make it right.
While the traction wheels are designed to use their own tires (which, I think lots of people will be VERY happy with once they have the opportunity to play with them) you can easily attach traditional roughtop or wedgetop treads.
The method I used:
1. Assemble the wheel.
2. Cut the tread to length.
3. Hold the tread in place with a few zip ties or a belt.
4. Drill holes through the ends of the tread through the wheel rim using a small pilot bit.
5. Fasten the tread to the wheel using rivets, or self-tapping plastic screws.
6. Remove the zip-ties.
I am experimenting with some self-tapping screws that work REALLY well. While I would personally use the VEXpro traction tires, we will make sure there will be good options available for those who want to use their own tread.

Can the Andy Mark alligator clips (am-0894) be used to attach the tread to the traction wheels?

Is anyone else having trouble adding the c-clip to the third stage on their Ball Shifters (our final stage is a 60:24, if that makes a difference)? When we place the 24-tooth gear on the shaft, the c-clip groove does not stick out as much as the instructions show. Within the next two days we will see if the same issue exists on the second shifter we ordered.

Should your mecanum wheels be really loud?
We haven't driven them yet -- we assembled one octocanum pod just to make sure everything integrated properly, and hooked the CIM up to a battery while the frame was upside-down on the floor. And it created quite a racket!
As far as we can tell it's the rollers rattling as the wheel spins. Is this normal?

According to the assemblers, the notch for the clip was partially covered by the gear.

Yes this is normal. When they are under load, they will not make that noise. We have driven robots around with these wheels on and they are not noisy at all.

Depending upon how much of the groove was being covered, this is normal. The groove is larger than the clip to allow for tolerance stack up. If the clip can't be assembled, then that is a different story all together. Did they try to install the e-clip?

Do y'all have any idea when the 1/2" hex bearings will be back in stock? They're an important part of making all of the rest of your stuff work right. :)

We took them out of stock to 100% inspect the runout based on the earlier CD post. They will be back in stock no later than Tuesday.

For what it's worth, we also experienced significant (visible) wobbling on 2 of the 4 1/2 inch hex bearings we ordered. I don't have a video of it, but I just wanted to bring it to your attention that it's probably not just an isolated case.

FWIW, of the 80 I just got, 20+ are so far exactly what we expected. There's a little variation on how well they fit on VEXPro .5" hex stock, but none of the 20 were out of center.

Ricky, Paul,
Any idea on when the Hex bore versa-hubs will re-stock?
Ed,
We are currently inspecting them. We will be putting some back in inventory late today, but a limited quantity. Basically, the supplier broached the hex such that some parts are seeing a .006" to .010" runout to the flat face and to the versakey pilot. We are putting the good parts in inventory and reworking the parts out of specification.
If you are in a pinch now and have access to a hex broach, you can broach the 1/2" round with keyway to a 1/2" hex.

We have a set of hex bearings that are off center. Who should we contact and when can we expect replacements?
We are finding that nearly all of our hex bearings are off center. I think this is becoming a major issue among teams not knowing when good parts are going to be available.

It is always a good idea to contact customer service at support@vexrobotics.com or 903-453-0802.
While John, Ricky and I check CD, our customer service department responds to customers who call and email. Every customer who contacts our support line directly is having their bad bearings replaced.
The issue that went undetected was that the hex was broached off center. Our standard bearing race runout test did not detect this failure mode. We have now set up a special hex runout test on every hex bearing.
The reason the bearings are out of stock is so we can replace all the bad bearings that have already been received by customers.
For extra information, only the 1/2" hex bearing is affected. The 3/8" hex bearing is not affected by the defect.
Paul
Thanks, Paul. I sent in a request for replacements.
We just got our robot driving today and encountered an interesting noise. After some basic testing we believe to have narrowed the noise down to our brand new victor 888s. When they are given a a signal other than stop they emit a buzzing noise. They appear to work correctly, driving our cims under a fair amount of load for about 5 minutes or so.
We were just wondering if this noise is intentional or not. What can we do about it, and is there a way to stop it?
-Thanks

The Victor 888 operates at 1,000 Hz which is in the audible range for us humans. The noise is normal and expected.
Paul
This may want to be noted somewhere official. We certainly found the noise a tad bit concerning when we first heard it.
There probably isn't anything we can do about the volume of it then?

We are back in stock of Flanged Bearing - 1/2" Hex ID x 1.125" OD (217-2734), although in a limited quantity.
Due to the limited supply, we are only taking orders for these via credit card over the phone at 903-453-0802. Limit of 10 per order.
Also, we are also back in stock on the 1/8" Delrin Washer (10-pack) (217-2758).

Any plans on stocking an 11 tooth CIM gear, like West Coast Products? (http://wcproducts.net/wcp-00001/)
It offers the nice ability to tweak the gear ratios in the gearboxes, without a massive change, and it's a product I'd really like to see.

I don't know that I have ever seen the WCP 11 tooth gear in stock. Besides, I doubt VEXpro can compete with WCP's price of $0.00.
On a more serious note, I second this motion. It offers a lot amount of design flexibility.

Usually you must contact RC directly. The site is sometimes incorrect and he offers other parts(i.e we got 254-esque WCD bearing blocks that are/were never listed on the website)

Just out of curiosity..... Does the part not being listed on the website, and only being available by direct contact, disqualify it as COTS?
I know we will most likely be having some custom wheels made by RC. So, how would those be handled on the BOM?

Until RC gets them going, Martin is the go to place for these pinions.

If you're paying for them you'd have to list the fair market value of the materials and labor that went into making them.

I considered that option but wasn't sure if galling would be an issue when mixing VexPro stuff with steel gears. Did anybody test that?

Are those machined from metal stock now?
pfreivald

Oh, as an aside, there was some question last year about how durable the VexPro mecanum wheels would turn out to be. At this point I can state that we used them aggressively all season and they've held up fantastically well.
AdamHeard

They were metal last year as well.
The VersaHubs for mounting a gear/sprocket to a wheel were plastic, but all the live axle hubs are metal.
There is something hidden in Aren's picture too. It's killing me that no one has noticed it yet.
