Post VEX Omni wheels
I worked on a VEX Omni wheel project last year. There was a key software function written to allow motion based on a compass type heading. The picture shows how the wheels are installed on the chassis. The video shows how sensors were used to track the table edge at high speed.
void robotmove(int heading)         //Function to move a specific direction
{  //Heading of 0 degrees is foreward, 90 is right, 180 is reverse, 270 is left
  lfspeed = speed * sinDegrees(heading+225);
  rfspeed = speed * sinDegrees(heading+135);
  lrspeed = speed * sinDegrees(heading+315);
  rrspeed = speed * sinDegrees(heading+45);
