Which of these two could suit my application? and How can they be operated within the PBP?

If this is what I'll be using I guess I have to buy two of these or maybe just use two PORTA pins of the 16F877 and remove two IR sensors (GP2D12) from the robot and build an IR Sensor which could output digital 1 and 0 signals from scratch and connect them to an available Digital I/O pin.
Where did you get your PBP at?
And I'd still not even mess with the MAXxxx chips and just use a PIC.
But if you're hellbent on using them, you answered your own question...
The MAX186 have a serial output, so use the PICs serial input...
