I guess the alternative is really just using spur gears. As a disclaimer, I have never built a crab drive, but I've seen a lot of them, and they typically just have the motor swinging around, attached to the drive modual in line with a spur gear reduction set... or something like my fancy pants picture below will show:
Whew.. that's too much artwork for me. I need a nap.
