Crab is simply a TYPE of swerve drive, but they are not the same. Swerve is just the ability to have sets of wheels that can rotate. Crab drive is a type of swerve drive where all the wheels are linked (mechanically usually), so they are always at the same angle. There are other types of swerves, including ones where each wheel is rotated independently (allows greater maneuverability and less skidding and much more complicated programming), and Winnovation's 6-wheel swerve.
