Re: pic: Pigmice Northwest Drive
Looks good! Only question I have is you called it "Northwest Drive". Is this any different from West Coast Drive? If so, what are the differences and advantages/disadvantages? I'm assuming the duel omnis on the corners are for ease of turning, and that there is no drop on the center wheel because of that.

Just curious, why the 4 inch wheels? The smallest I've heard of in the past are 6 inches. Also, don't be nervous about posting stuff on here. It looks really good and you should be proud of your work. We may ask questions, but we try not to be too scary.

Re: pic: Pigmice Northwest Drive
I like it, but how are you attach your SS? and why did you make a "V" in front instead of adding a front rail because the rules for the bumpers this year would not allow that. How exactly are you planning to mount the bumpers to the 1' alum. tubing on the sides? and do I spy a custom center wheel? last question I promise, hex axle or keyed axle?
But looks great keep up the good work |

Re: pic: Pigmice Northwest Drive
Thanks for the responses. I knew there was a good reason just couldn't figure it out. I still have my reservations about such small wheels, but that is probably just because they are new to me.

Re: pic: Pigmice Northwest Drive
I've been thinking of a similar design, but I was planning on using 4 plaction wheels in the center with the 4 omnis in the corners. I believed this would help increase stability from being spun by other robots.
8 wheel - 4 plaction center, 4 omni corners for stability and forward pushing. No drop. Anybody think the 4 wheel center would actually do anything to fight being spun from other robots pushing your corners? |

Re: pic: Pigmice Northwest Drive
Many times it has been said that you shouldn't bother shifting if you are gonna have omni wheels. It's fairly accurate. You can do the math if you like, but it will be easier to spin the wheels and you won't win many pushing contests.
One other note: Low gear is defintely too slow. This past year we ran a similar speed w/ 13fps and 3.5fps. In low gear we could push without issues, but it took a very long time to get anywhere. It really wasn't worth it. Try gearing your low gear closer to the traction break point. Which will probably comeout to be 7-8fps. |

I know our driver stayed in our 17fps high gear 90% of the match, if not more. |

However, I do feel 13.5s is a bit slow for most games, 15-16 is much nicer. |
