New HW design - Omni Wheels and 30kW spinner

Yeah, I was thinking along the same lines, that's why the ring has to be so thick.
I was planning on adding some steel for the bearings, clearly hardened steel vs ali is not a contest!

I might have been over exaggerating a bit. I think 1500 rpm is a bit more realistic as a normal speed and be able to run it up to 2000rpm if we need the extra power.

We did make a spreadsheet with some crude way of working out the stats for other spinners:

Although it is based on energy calculations not torque so isn't very accurate.

It seems that most people put lots of weight on their discs and forget that the energy mostly comes from speed. Hence why we want a lighter ring. I know that bite is important too, which is why we want such a powerful drive system. However I think that having too much bite can be your worst enemy, since you put a lot of the energy back into your own robot (which would be bad since as you said it would probably deform the ring).

The main strategy is going to be dodging them as they try to ram/flip/hit us and then hit them in a weak spot.
