what is the control circuit of a 12v dc gear type motor?

I need a control circuit or a schematic diagram for a gear motor to make it run and stop. It is being used in a magnetic pick and place using four bar linkage. The gear motor will run if the inductive switch detects metal found in the detection area and stop if  the metal is carried by a magnet and transferred to the designated area, and the four bar linkage or the gear motor will stop respectively. If you have questions regarding this details please ask me to make it more specific.

I guess you need on/off forward and back?? Then you need an H bridge - Google is your friend.

I worry about your skill level if your embarking on a complex project with so little basic knowledge??

sir thanks for your honest wonderful comment, but the motor should never be used in forward nor backward. The motor will constantly turn clockwise. the four bar linkage application is being used that is why it will go forward and back. It is like a wiper motor found in mobile vehicles. Now I know already its just a simple circuit to be made. And I am thankful for your time to read this problem.
All you need is a couple of relays.

Are these three questions for the same undergraduate robotics project? Could you provide some information on the class and professor?
