You haven't told us anything about the setup on your robot. Please describe what wheels you have on your robot, how they're connected to some motors, and how the motors are connected to the control system. There's literally thousands of places that a mistake could have been made, and additionally, the term "Holonomic" is less-than-fully understood by the community as a whole, and different people will often take it to mean different things.
