Re: jaguar not working

Weve had problems with the jaguars and found that if the pwm value is full 1.0 or -1.0 the jaguars may break. so we basically capped our values at 0.99 and -0.99 and we really havent had a problem since

Re: jaguar not working

we havent tried this yet
and for the sake of getting our robot working we are willing to try
would you mind sending us a link to (or instructions) on how to cap the pwm values?

Re: jaguar not working

This i got from the site i mentioned earlier:

CALIBRATION
PROCEDURE
To calibrate the servo-style PWM input for a specific range, connect a PWM source, then:

1. Hold down the USER switch with a straightened paperclip.
2. After 5 seconds, the LED flashes Red and Green to indicate Calibration mode.
3. Instruct the controller to send a full-forward signal.
4. Instruct the controller to send a full-reverse signal.
5. Instruct the controller to return to a neutral signal.
6. The LED will flash Green and Yellow to indicate a successful calibration.
7. Release the USER switch. The MDL-BDC samples these signals and centers the speed range and neutral position between these limits. A calibration failure will be signaled if an out-of-range signal is detected.

We also did. Someone on the forum PM'd me about it after he saw my post when I said we had a problem. I sent it to our head mentor, who may or may not have done something. Judging from their response-the message seemed to be sent personally to our team (me, because I posted our problem)-their support is very good. How'd yours fail? I think I heard something about a blown resistor on ours, but I wonder if it's the same thing as what happened to yours. It would be cool to know, the jaguars have some nice features that might be enabled next year, or later in the future. Although we can't use them now (too late and we only have one left...), it would be nice to work with them on the off-season time.

Re: jaguar not working

Hello,

In case this information could be of use on this thread...

To reset the servo-style PWM input on the MDL-BDC Jaguar to the default factory range:
1. Disconnect the power to the MDL-BDC.
2. Hold down the USER switch with a straightened paperclip.
3. Reconnect the power to the MDL-BDC.
4. After a moment, the LED flashes Red and Green slowly to
indicate a successful calibration reset to factory settings.
5. Release the USER switch.

Regards,
Scott
