I am working on a 4x4 9398 with 4 motors NXT and 2 servo for drive ;
The motors are strong ;
I use 2 MUX to get 4 motors with the drivers from Xander ( thank to him !
and a PSp witj drivers from Xander also
the MUX use 2 ports ; it would be better to use only one , but it need to have 2 I2C adresses for MUX ,and it seem not to be OK with the drivers ?
if so I could use sensors to drive the 4x4 as a robot ;
the drive for wheels is bad : the servos are weak ; it would be better to use the new servos from lego ,
but I do not know how to do as the drivers for PF seems to be for M or X motors only ( ? );
I hope to improve it ...
