I can't see your picture right now, but basically yes - you need an H-bridge, either made with transistors, or made with relays (more or less limiting you to full on or full off tho).There are several H-bridge controllers available, such as L293 or L298, do a litle searching for their equivalent if you need mroe current control (you need to take the stall current of the motors into account whens selecting your parts).
