Questions about mecanum wheels

What is your wheel config?

Here is the code I've done for off season projects, you may want to add dead zones. This also does not have the power problems -

                if (ws.ButtonState.Two == true)
                {
                    leftmotorcontrol.motors[0].Velocity = -100 * (ws.AccelState.Values.X - ws.AccelState.Values.Y + turn); // front left
                    leftmotorcontrol.motors[1].Velocity = -100 * (ws.AccelState.Values.X + ws.AccelState.Values.Y + turn); // rear left
                    rightmotorcontrol.motors[0].Velocity = 100 *(ws.AccelState.Values.X + ws.AccelState.Values.Y - turn); // front right
                    rightmotorcontrol.motors[1].Velocity = 100 * (ws.AccelState.Values.X - ws.AccelState.Values.Y - turn); // rear right
                }
                else
                {
                    leftmotorcontrol.motors[0].Velocity = 0.00;
                    leftmotorcontrol.motors[1].Velocity = 0.00;
                    rightmotorcontrol.motors[0].Velocity = 0.00;
                    rightmotorcontrol.motors[1].Velocity = 0.00;
                }

The if statement is a safety measure

I was using a wiimote so the "joystick values" (Really i used the accelerometers) gave an output of -1 to 1, you get a 0 - 255?. Its really simple just add up the x,y,z(rotation) and give each wheel the values they need.Diagrams help alot.

Are you using two or one joystick?

Take a look at this thread -

PM me if you need more help

A piece of advice that I'd give is to also use a PID controller. This way you can tweak values to however you'd like them. Also makes for smoother control.
