Problem with the Sumobot...

Ok, we all know that this bot has two motors...but the right one doesn't seem to take any commands that I give it...CORRECTLY.

For example: you tell it to go forward, it goes backward...you tell it to turn, it does reverse, etc etc etc.

Basically, ALL this moter DOES is do reverse!

Anybody know how I could fix this motor? Please help..

By the way, if the problem is in the chip instead of the motor, how could you reset the chip?

    Hello,

    ·· Have you centered the servos?· The Motor Alignment program is listed on Page 15.· This step ensures the Servos are properly centered.· If this step isn't completed properly, you could get the symptoms you're seeing.

    Did you center your servos using the MotorAligment program?

    If you swap motors does the problem move?

    If you have a palm try deactivating HotSync. I had the same problem and I deactivated the HotSync manager and then my motor work perfectly.
