Computer controlled "Tank"

hello all ! , im new here and this is one advanced creation of mine which im going to submit here and follow up on its development .

Its a tank i made that is controlled via a computer , now its being wirelessly controlled via RF modules and a 4 channel serial relay controller converted to USB by the means of an FTDI chip . the aim is to fit it with some sensors that relay back to the computer , which map out a certain block of a room for obstacle avoidance and memorizing obstacles ! , a smart program will be made to give the tank positions to go to autonomously !any question regarding this is welcome , i feel i have not talked to much about it , but every thing will be evident i guess after answering your inquires :) 

here are some more pics :

The software and source

UPDATE:

new development ! , i spotted a big old retired bomb disposal robot at UNI ! that im planning to rewire to become an extended development of this project , waiting for approval to start the conversion . the robot entitled has a hydrolic arm as well . this is me inspecting the rover . more details as the conversion starts :)
this time i think i will use blutooth , with a blutooth enabled laptop inside the tank , and a mobile phone for control ,it can be accomplished with a wireless wifi network as well , a server client model or even adhoc . well we will see where the wind takes us regarding this project , but since its huge i guess there is room for a mobile controller and a client server system with a camera and the such .
