Tamiya 70097 motor sense

(First of all I apologise for my poorness speaking english, i hope you can understand me)

Hi, I'm working in a school proect and I purchased a tamiya 70097 twin motor gearbox. I have seen how many people used it to make robots which detect obstacles and avoid them with ultrasonics sensors, my project is pretty related to those but i dont know how to spin the robot in different senses(to turn left or right).

Well this is my doubt and I would really thank anybody who could help me know how to turn the spin rotation sense.


Gratefully, Nicolas.
