Wheel Size?

[couvillion]

Along the lines of cool and not really helpful.



I have not been able to come up with a engineering reason as to why tri-star wheel is better than a regular wheel of the same over all size. But like the design all the same. For those that aren't sure what is going on here it is the same setup as a planetary gear system with the ground acting as the ring gear.

I remember seeing an old 2004 clip on youtube with a bot that used them to climb the stairs...

That was 1218 The ChaBots. They made it all the way to the Einstein Final that year. They were pretty hard to stop, even if you dropped a robot on them.

Slightly irrelevant, but I remember a team that had a large gear dropped on their robot during shipping. That would suck.

340 also had them on Einstein in 2004.
