I think... I THINK you have a wiring error... I've been trying to see which jag goes to which motor. From the first video... the black jags run the same direction and the gray run the opposite of the black. However... you seem to have the outputs of the black jags opposite each other. So that means one black jag running the left side and one black jag running the right side. The corresponding gray jag of each side would have to have the output opposite of the same side black jag. So I think you need the jag like this:


Battery

one side

one side
other side other side



but not sure this explains why it works correctly slow unless one type jag overpowers the other type at low speeds... no info on that.


Anyway... for a test... set the bot on blocks, disconnect the pwm from one jag from each side and see if you get what you expect in motion.


Hope that helps... I have a similar problem but that usually ends up being my own stupidity... can't be helped... I AM a professional after all...
