RF module .. PIC16f877A

how to connect this Rf module

http://www.robokits.org/products/?p=productsMore&iProduct=34&sName=RF-Modules-(Tx--Rx-Pair)-433-Mhz-ASK

to PIC16F877A
I need to move my bot to a distance avoiding obstacles ... I want this transmitter to connect to a dumb terminal .. ( ei providing only power and GND) this can be moved from place to place ... now my bot will move towards the transmitter using the receiver... and avoiding obstacles...

I have already completed my part with avoiding obstacles...

Please Help...

thanks in  Advance

That pair of Tx-Rx modules is thought to transmit data serially over a short distance between two microcontrollers, not as a guidance.
The best thing you could do with them is a remote control for the bot.

then what can be the solution to my problem

You need a directional system.
Light, laser and IR can be directional, a self made small power radio emitter from a few turns of wire could also be made directional, a line following bot is also directional.
Besides the small power radio emitter, there are many projects on this forum. For the small directional radio emitter maybe someone with more experience could help you.

You can connect these RF modules to your UART, but you need to design a good error detecting protocol as these modules are very error prone.

Then you can move your bot accordingly via sending commands.
