Hey guys this is my first intractable, so please go easy on me..
What I have built in this intractable is a Robot. I call it a spy Robot (cos if built small and if a camera is added it will act as a spy). Any ways, due to time constrain and lack of sufficient funds, I could only build a basic (a huge one and not the micro robot, which I initially planned) model of the robot. I have programmed (Assembly language) the robot  for additional motor control for camera and other switches though.
The basic movement that would happen is the forward backward and the left and right movement. We could also add a camera to it, if required. For some people this would be like a 'Neanderthal Robot'. Any ways I know the pain that went into this. This is also my collage project, thanks to my project partners, Sandesh Davli, Sanjiv Vishvakarma and Jugal Makwana.

They're all there.

You didn't say that, you said "circuit diagram???" anyway, any small signal NPN transistor would work there - BC182L or similar.
niceeeeeee.......!!!!!!!!!!!!!
u have done very very very great job dude!!!!!!!!!!!!
i like it!!!!!!!!
keep it up dude......!!!!!!!!!
Nice piece of work. Its apity you can't format the code better here.
