StrMNXA great looking robot. Although i'm curious, whats the speed/gearing of that drive train?

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

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?

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.

Fusion_ClintAs 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

There are four inch wheels touching the ground, and what appears to be less than a 2 inch gap between those wheels and the member above them spanning the length of the robot. The bumper can likely touch that frame member along its entire length, fully meeting the rule. I don't see the issue here?

Cash4587Could 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.

Jay BurnettWe are going to be assembling our drivetrain with Vex Omnis and Versahubs today and I am wondering if the hubs just press fit into the wheels or if we need a bolt to run through and clamp them in. Thanks and Nice looking robot!

That seems like a decent speed for a 6-CIM drive on a field as open as this one, but I agree current sensing is wise.
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? |
