RELAYS and THE motors

I need to know how the relays and DC motors are interfaced. . . In my project we need to make the motor rotate in both forward and reverse direction. . . . . . .


4 wheels are there and 2 dc motors are connected to 2 wheels so that when one motors rotates then the wheel rotates right or left direction. . .if both rotates in forward direction then the vehicle moves in forward and similarly in reverse direction. . . .

now i need the circuit how to do this. . . .i use a relay driver IC uln2003. . . here is the circuit i got. . . .i have to know how the 4 relays are interfaced with 2 DC motors .View attachment 62305

is this homework?

Have you considered that there needs to be a delay to allow the motor to stop briefly before its rotation is reversed?
Are limit switches needed?
What motor voltage/current has to be switched?
Is electrical interference suppression essential?
How many poles and ways do the relay contacts have?
