negative on that, thats simply referred to as "wide drive" style.
Crab drive is where the robot has the ability to rotate its wheel effectively steering them, while having them powered also. There are many different styles of doing this. Do a quick CD-media search for "crab drive" or "swerve drive" and you'll see plenty of examples.
