How do I program a four wheel drive?

[rian]

So basically I’m trying to program a four wheel drive (Ri3D robot). I’m assuming I just configure it like each motor as itself instead of as a drivetrain? Is there an easier way to do it? Also, instead of coding each motor to “spin” can I command it to turn for a number of inches? Or how many spins is each inch? Thanks.

If you are using VexCode, here is an excellent explanation. It covers drive trains with 4 motors and also drives with and without gyroscopes.

VEXcode, motor groups and drivetrain example

There have been quite a few requests for instructions on how to use motor groups and creating a drivetrain with more than 2 motors in VEXcode. I’m going to discuss these classes a little and provide a simple example. What is a motor group ? A motor group collects two or more motors together and allows control as if they were a single entity. Just about all motor class member functions (by that I mean spin, spinTo, setVelocity etc.) are available on the motor group class. We introduced motor…
