help with 6wd chassie..

[Magic]

Hello guys!

I'm 17 years old, and robotics is a big interest of mine.

Recently, I built a 6 wheels drivetrain chassie with a 1/8" center wheels drop.

the chassie looks like this one (the only defferance is that i'm using 2 motors in each side with one gearbox, two motors that goes to the same gearbox):


my problem is that i'm not a programmer, so i can't drive it. i wish someone can provide me a good code, which is Appropriate for 2 joystick drive so i can try it (one joystick for the right wheels and the other for the lefts).
please provide me the best code that you can, because i know nothing about programming and i can't amend the code.

in addition, i'll be very thankful if some one can provide me with a geartooth sensors code for this drivetrain (2 geartooth sensors, one for each gear).

thank you alot!
