Re: pic: Uber 3.0

I am going to differ from the crowd and say that the high gearing is OK.

here's what you do:

in the code, use a button/toggle to scale back the joystick inputs to create a "virtual gear". you can also route this to a throttle if you are using joysticks instead of a gamepad. my team has a demo bot made from an IFI kit chassis and the 2011 kit cimlple gearboxes... we had to make the output cog larger to fix chain tenison issues and as a result, we had to map a scalar to the left joystick throttle (in arcade mode, the only stick) since by default it was too fast.

this year's competition mecanum used a "turbo trigger" to give the motors full power, otherwise, the joysticks were scaled back.

the only other note is you will have a lot less torque but depending on what you want to do with it, this may be more or less of an issue.
