Consider using a voltage control for each motor and use that combination to
steer the robot. You most likely are sending a voltage signal now, and it
may not be too difficult to change your design by adding one more to your
joystick or to your servo controller. You may be lucky enough to get a
balance of speed with a circuit divider and resistors, but the instant you
load one motor more than the other you will be back to square one.
