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. |

Re: pic: Pigmice Northwest Drive
Agreed. I could probably count the number of times we used low gear in 2011 on one hand. Low gear is one of those things that is rarely needed in everyday match play. However, when we need it, we really need it. You can probably make low gear faster than 3.6 ft/sec, just make sure it's traction limited.

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