Re: Speed or Torque? Drivetrains

I`m experimenting with a high speed ratio for sack attack......... that works

Did you search on VEX forum? I'm sure there are some findable examples, but if you need more help PM me.


On a different note, when you're talking about drivetrains, force is the measure of how hard your drive base can push (not torque or power), and power is the product of force and speed, which does not indicate a certain speed or torque, just their relationship.

While transmissions are cool in VEX, they take time to build and perfect. Odds are we will be going with some kind of mecanum drive base this year since that's our team's thing. By deciding to not focus on something like a shifting transmission, we can spend more time on our game piece mechanisms and on autonomous programming. It's all about design trade-off's.

Omni drive with a high gear ratio and they won't be able to catch up to you

Re: Speed or Torque? Drivetrains

I think that if you're going holonomic (which looks like it will be popular this year), direct-driving with 393's seems like a good option because you get a good amount of both speed and torque

Here ya go Richard. CLICKY
Use Murdomeeks example, much easier to follow, and he has pictures and videos of it. Really easy to implement and MUCH easier than using a piston gearshift.
