mousebot JR

hi i am making a light seeking mouse bot using a op amp and 2 photocells,

but i would like to have 2 more photocells that can control the dual motors the same as the first two, but i want the second pair of photocells to override the first photocell circuit, only when it is actively receiveing light.

what would be the easiest way to do this?

could you post a schematic?

here is the schematic im going to use, note that R1 and R2 are cds cell equivilants,

if i didnt mention i need the override circuit to respond even during minmial light levels

also i was wondering, can the op amp handle driving those motors or would it be smart to leave the transistors in there?
