From bobcook at shaw.ca Tue Jun 21 18:45:01 2005 From: bobcook at shaw.ca (Bob Cook) Date: Tue Jun 21 18:45:51 2005 Subject: [WheelWatcher] When is the CS-100 required? Message-ID: <41185382-2EE2-4D98-AC42-BBD7FCEE7C83@shaw.ca> Hi, I'm confused about the CS-100. On the Nubotics website, it says "Compatible with Solarbotics GM-2, GM-3, GM-8 and GM-9 gearhead motors (CS-100 recommended with GM-3 & GM-9)". Later there is justification for requiring the CS-100 because "due to their longer motor shafts, you will also need the CS-100 codewheel spacer. This . 1" thick spacer lowers the codewheel sticker close enough to be in range of the sensors." I think this information is incorrect. The Solarbotics GM-2 and GM-3 are the motors with the longer shafts, while the GM-8 and GM-9 have shorter shafts. You can see pictures of the Solarbotics motors on their website. It would be good to update the Nubotics website as well as the Acroname website with the correct information.

Sorry about that -- good catch. > I think this information is incorrect. The Solarbotics GM-2 and GM-3 > are the motors with the longer shafts, while the GM-8 and GM-9 have > shorter shafts. You can see pictures of the Solarbotics motors on their > website. We actually own a few sets of all four varieties, but managed to get mixed up about the differences while creating the webpages. The GM3 and GM9 are similar, in that the output shaft (at the end of the geartrain) is at a right angle to the motor shaft (at the start of the geartrain). Conversely, the GM2 and GM8 have parallel output and motor shafts. On the other hand, the GM2 and GM3 share the same gear reduction ratio -- 224:1, compared to the GM8 and GM9, which share a 143:1 gear ratio. In addition, as you point out, the GM2 and GM3 have long shafts (indicative of similar geartrains), and the GM8 and GM9 have short shafts. So, we made a mistake in recalling which property was shared by GM2/GM3 GM8/GM9 vs. GM2/GM8 GM3/GM9; there are a lot of combinations. Phew. > It would be good to update the Nubotics website as well as the Acroname > website with the correct information. Yes, thanks, we just made the corrections based on your feedback. Turns out the Product Manual was correct, BTW. Acroname is not yet selling the CS-100, though they will soon. I'll make sure they have the correct information. Please accept our sincerest apologies if this has led you to purchase the wrong items. -Pete Nubotics Support From bobcook at shaw.ca Wed Jun 22 21:14:50 2005 From: bobcook at shaw.ca (Bob Cook) Date: Wed Jun 22 21:15:19 2005 Subject: [WheelWatcher] When is the CS-100 required?

I'm using GM-9 motors on my robots so I had started to fabricate my own replacement for the CS-100, and when I started to take a close look at what was needed I recognized there was something wrong. So I investigated a bit more, and then it seemed obvious what had happened. You need to update another reference online: http://www.nubotics.com/ products/ww02/index.html Not sure which documentation you were referring to. The booklet from Acroname doesn't refer to the CS-100 (or anything except the GM-8 motors) at all. Anyways, its a nice product.

Let me know if that does not fix the problem you are seeing. If still wrong, what specifically is not correct?

Their booklet is based our user's manual here: http://www.nubotics.com/products/ww02/ww02-product_manual.pdf Of course, now I notice that the manual uses the old part number for the spacer (CS-040) not CS-100. Ah, perfection, she is elusive. > Anyways, its a nice product.

In fact, the GM-8 and GM-9 both work well without the CS-100 -- it is the longer-shafted GM-2 and GM-3 that need it. Thanks Bob. App Note ---------- We have posted App Note AN01, "Compatibility of WW-01 with Wheels and Mechanisms": http://www.nubotics.com/support/ww01/appnotes/AN-01.pdf This explains which common wheels work and don't work with the WW-01 using the various Codewheel Spacers. WW-01 Update ----------------- We will soon be shipping to distributors an updated version of the WW-01, with Rev C of the printed circuit board, that fixes the inconsistent pin numbering on the silkscreen with regard to the pin numbering on the connector and header. Pin 1 on the circuit board now corresponds with pin 1 as indicated by the triangle mark on the header and on the connector housing; this is now consistent across all products, including the WW-02. Note that existing cables continue to work -- a cable that works with a Rev B board also works with a Rev C board, as the change was merely cosmetic. The updated WW-01 also includes a new custom spacer that eliminates the need for washers with servos from Hitec and Futaba. Installation is now much easier. WheelCommander WC-116 Differential Drive Controller ---------------------------------------------------------- We are finalizing the firmware, finishing the manual, and preparing to ship units to beta testers. We are very excited about this new product, as well as its future companion, the WheelDriver WD-122 dual 2A h-bridge. If you have interest in evaluating the product by participating in the beta test program, please contact: info@noeticdesign.com. Feedback ---------- How are you using your WheelWatchers? On a standard robot kit, a custom robot, or not a robot at all? We're always interested in hearing how you are using our products. If you have a website that features your robot, or photos you would share with us, please send them to: info@noeticdesign.com. Thanks. Sincerely, Pete Skeggs Nubotics Tech Support
