Typically for a tank drive, the steering wheel is used for turning. Velocity in the forwards and backwards direction is controlled either with a joystick next to the wheel or buttons on the wheel, or even pedals on the floor.

In other words: Turn wheel, turn robot. Apply throttle, robot moves in the direction it is pointing.
