essentially crab and swerve are similiar, but few differences. i believe that a swerve drive has one wheel that turns like a turret and having only 3 wheels in total which are all driven. so in crab all four wheels are able to spin like a turret and be driven. in omni the wheels are stationary and turn in similar direction to the way there paermanently mounted too. there are little wheels that make up the circumfrence of the wlarger wheel, say someone is pushing you from the side omni wheels allow the robot pushing you to move you a lot easier.
