What size & type wheels do your team(s) use, and why? Also, if you use drop center, how much and why?

What type of wheels does your team use?

Our team is looking at what wheels we should use for next year. A couple of our AndyMark HiGrip wheels shattered, and we don’t want to have that happen again. We have also had issues with our Vex Traction wheel treads wearing down very quickly. What teams does your team use, and why?

Why do we drop wheels?

Why is it done? Why do we drop the center wheel on drivetrains? Why not just drive with all 6 wheels touching the ground? So many teams do a center drop of 1/8 or 1/16 and I can’t seem to fathom why.

Which wheels are recommended

Hello, If im going for 8 wheels at all, and 4 of them are omni wheels, that are placed in each corner, and my question is, which 4 wheels should i use in the middle of the robot to get smooth turns?

How to decide which kind of wheels to use?

One of the shafts of the wheel stuck out during the match, this resulted in only one side of our robot available moving. We want to fix and upgrade the robot. How to decide which kind of wheels to use? Omni, duraomni, mecanum and pneumatic? And what size is better? 4" or 8"? Thank you!

How to center drop a 8 wheel chassis?

So I am looking to design an 8 wheel drivetrain for the offseason this year. It would be my first time designing a drivetrain and hopefully would be my teams first custom drivetrain (we have been using mainly the KOP drivetrain). I understand with a 6 wheel drivetrain, the centre wheel is dropped slightly to avoid having the drivetrain rock and shake when turning and to keep the wheels from wearing out too much. What I want to know is what would be the “centre wheel” of an 8 wheel drive. do I dr…

How do you implement a non-center drop with omni wheels?

We haven’t received our shipment yet, but trying to get ahead of a problem we noticed in the CAD files. Our plans are to run no drop, VEX traction wheels, and VEX omni wheels. When looking at the CAD drawings we noticed the traction wheels are 6.25" instead of 6", and this will give us 1/8" of drop. The Versa Blocks have some adjustment built-in, but not enough for the 1/8" we would need. How are other teams getting around this? Just running a drop? We are trying to keep them as thin as po…

Can you change the wheels on the KOP drivetrain?

We wanted to use pneumatic wheels to help with our climb but the team wanted to use the KOP drive train, would it be easy to switch out the traction wheels for pneumatic wheels?

8 Wheel WCD Question

Quick question about a 8 Wheel WCD Chassis: should all axels be floating and have a cam for tensing or should one axle be locked in place with bolts using the provided mounting holes in the VersaBlock. Is there a census on the best setup for VersaBlocks on an 8 wheel chassis? Thanks in advance!

Mixed-size wheels?

In theory, it’s possible to drive mixed sized wheels by using pulleys or sprockets with identical ratios. So, put a 24 tooth pulley on a 4" wheel and a 36 tooth pulley on a 6" wheel. In reality, I’m worried about the 6" wheel actually being 5.95" and the 4" wheel actually being 4.03", in which case the wheels would constantly fight each other. But, that problem also exists when you have different wheels of the same nominal diameter (e.g. a 6" traction and a 6" omni), and doesn’t seem to caus…
