How are you properly going to use the NavX as it is mounted on the side of your robot?

Re: pic: Team 5624 Steamworks Robot Teaser
Why do you have shaft collars on your drive shafts? You're using thunderhex. Just tap it for 1/4-20 and use a washer + bolt to retain the wheel.
Or is this a conscious design decision I'm missing? |

If you have the space on the end of the shaft for a shaft collar, there's really no downside to using BOTH a shaft collar and a tapped 1/4-20. Extra security.

I'll be that guy:
I assume you have a plan to have your side bumpers properly supported per R31, and it just isn't visible yet? Front/back look to be OK, if the bumpers will fit within the volume. *Disclaimer: This is CD in Week 4 of Build Season, not your first event, so any rules concerns and/or rulings are based on what is presented here, not the inspection at said first event. There is zero chance that "But CD said it was OK" will get you through inspection. |

Re: pic: Team 5624 Steamworks Robot Teaser
As long as that 1X1 tube running front to back is 7 inches or lower and that is backing the bumper it could work, I'm guessing the lower edge is at 6 inches. I will recommend bringing some support closer to your wheels either way.
You climber is interesting, it is the first one I've seen in awhile that I think has a chance of actually pressing the touch pad. |

Whoops! Didn't look close enough in the picture to see if there was an omnimount underneath. Figured I would say something just in case though ![]() |

Re: pic: Team 5624 Steamworks Robot Teaser
No, I don't think there is an omnimount. You can programmatically callibrate the Navx to work correctly in any configuration because it senses on all 3 axis of motion.

Re: pic: Team 5624 Steamworks Robot Teaser
Could be very wrong when saying this, but I really don't think you're going to get 11fps out of this. 3cims on a 50:14 and a 44:30 reduction comes out to be a 5.24:1 overall ratio for a theoretical of 17.76fps or 14.39fps adjusted. That gearing is very fast and you could be prone to brown outs. I would do some testing and adjust your drive speed accordingly.

If you really are geared for 11fps, consider going up to at least 15 or 16fps to take advantage of the extra acceleration of 6 CIMs. Your robot looks very cool! Is that a wooden polycord pulley on the bottom? |
