I am entering too.
I would like to put up a tutorial about my microcontrollerless line following robot. The total cost of the robot is below 40$! The robot can also be used as a photovore, light avoider and obstacle avoider.

Here is a video of my robot in action.

Im entering on this one as well! ;)
The robot is called: iBB (Eye Biped Bot)
Its a hardcore robot which catch up its loss on engeneering with its funny charm ;D. Its going to be built simply with a servo controller but no programmer for the code to run on, which means the robot will have to be connected to the computer at all time to be moving. The code took me some time, but after searching the web i found enough info to put it together. After the code is done running a window will pop up, making it possible to control the robot from a simple key press on my computer keyboard. I can re-program it, but right now a the two servos are controlled like this:
S = Servo 1 moving clockwise | X = Server 1 moving counter-clockwise - D = Servo 2 moving clockwise | C = Servo 2 moving counter-clockwise
The code is written in C++ And will only run the servos to some degrees before the keyboard press window pops up and takes the control over the robot's movements. Each keypress will only move the servos 1 degree. The servos are middle sized but powerfull for the low cost. The servo controller i used is the Pololu Micro serial servo controller (http://www.pololu.com/products/pololu/0207/ (http://www.pololu.com/products/pololu/0207/)) with a USB to serial adapter (http://www.pololu.com/products/pololu/0391/ (http://www.pololu.com/products/pololu/0391/)) transfering the code from my C++ computer program to to the Micro Serial Servo Controller.
I will set up a member turtorial account as soon as the system is back up running, seems like admin is having som problem with it (have read some treads about the problem :D keep on working admin ;))
Here's some "work in progress" photos of the robot:
