Hello i have a question can somebody help me with this?
my picar-x is going into right and trimming is making it worse i don´t know what to do ? please help me 
yeah but this is because my motor is slower than second
so how can i increase speed of one motor
Youre correct, i linked to the wrong post. I’ll delete it to avoid confusion.
Due to the mechanical design of the TT motors on the PiCar-X, the two motors may not run at exactly the same speed. Unfortunately, there’s no hardware fix for this at the moment. The best workaround is to add some offset values in the code to compensate."
