If simplicity is important, you can probably do without a motor controller altogether, and just use relays or transistors to switch the motor current. You won't have speed control, so you'll have to choose motors that run at reasonable speeds on the voltages you have.

I don't really understand how motors are controlled in r/c cars or robotics.
