Re: Spikes

Like I said above, more than one way to skin a cat...

I agree completely with Mr Gross. The Bobcats have never calibrated a Victor in all these years. We depend on the fact that 0 will give you -12V to the motor, 127 will give you 0V and 254 will give you +12v.

What some of you are addressing is joystick calibration which we address as a software issue or not as all... Even if you were to get perfect calibration of the joysticks, you have the motor issues to deal with (they are faster in one direction than in the other).

We have found that the drivers, if given sufficient practice time, can do wonders with complex and non-linear systems.

Last note: With default settings on the Victors, they can be swapped with impunity. With proper trim on the Joysticks, they can be swapped with just as much confidence. It makes troubleshooting much much easier and safer...
