I'm currently working on an arduino-raspberry pi based RC car.
My only problem left is, that I'm not able to drive curves with my motors.
Everytime I try to do it, I just get weird beeping noise. Adjusting frequencies doesn't change that.
I'm using 6 AA 1.5V cells to power the adafruit motorshield.
Do you have any suggestions how I can achieve a better driving?
If not - do you have any idea where I can get usable motors in short time? I'm from Germany.
The currently used motors where bundled with my Alu Robot Platform from sainsmart.
They are quiete similar to those: http://dx.com/p/dual-axis-reducer-motor ... -6v-185017
I'm not sure, how I can replace the motors, because they have kind of a transmission. (The yellowish around)
