check that guy out, a lot of seasoned veterans comment on what the difference is...essentially theyre the same thing
I admit I worded badly, below is the definition from that post that makes the most sense to me. I designed my bot to be coaxial swerve, but it is set up as crab drive in the picture because all the wheels are attached.


Definition:
Crab- having all wheels rotate together (ie: locked to the same angle). Derived from the ability of a crab to scuttle in any direction.

Swerve- Either all wheels can independently rotate, or they rotate in sets of two. Allows you to both translate and rotate, as well as drive the robot using ackerman steering, or monster truck steering where the front wheels turn one direction, and the rear in the opposite direction.
