A picture of the board really helps here but as I can see the only thing you have to do is to plug the 6 pin ISP
to a programmer and you have both power and a programmer attached...
What is your level of experience with electronics....
Do you have a programmer... you ought to... If not either make or buy one...

See http://www.societyofrobots.com/robotforum/index.php?topic=3292.0 (http://www.societyofrobots.com/robotforum/index.php?topic=3292.0) as to how $50 robot should be linked/soldered

Go to atmel home site and download PDF of AtMega8 if you wan to see more detailed info of pin outs etc.

Hmmmm I recommend reading the $50 Robot tutorial carefully. Its a different chip, meaning the pin #'s are different, and the code needs some minor modifications, but otherwise its almost exactly the same steps.

The tutorial will explain how to do everything, you just need to think about it a bit to see how things are different.
