I am trying bring up simple android controlled car using raspberry pi.
I tried following robot platform from sparkfun. I connected one L298N with 2 channels to control 4 motors. 2 motors from each side i connected to 2 channels. I don't see any problems in moving forward and reverse directions. But for turning left or right, somehow it is not working. For left, I am trying to reverse left motors and forward right motors. I tried on flat surface and carpet.. somehow looks like not motors doesn't have enough power to turn. Till now I tried 2 different robot platforms, both have similar issue.. I feel something wrong with my approach in turning. Can anyone please suggest better way to turn?
My robot platform.
I tried following robot platform also.
