Unable to calibrate controller

I have two teams/robots that when the robot is turned put into driver control, the robots move by themselves without anyone touching the controller. We have tried to calibrate the controller multiple times (30+) over the past 3 days, but we can’t get anywhere near the values 0 127 255. Either A or D is off example…58 146 227. Is there anything else when can look at to fix this issue. We have upgrade to the lastest firmware 1.08. I am at a loss of what else to try.

Hi ashlandrobotics,

We are sorry that you are having this problem with the Controllers. To help us provide additional assistance, we have a Youtube tutorial video on VEX IQ Controller calibration process:

Please follow this procedure closely. Are the joysticks A and D consistently off by the same amount on each calibration attempt or are they off by a random amount? The calibration process has time limit where it stops looking for calibration values, so it is possible that if done too slowly it may appear to not calibrate correctly.

If you need additional assistance, please contact VEX technical support at support@vex.com or 1-903-453-0802.
