Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

i am new to robotics (this will be my first real robot) and i am planning on building a robot car.
basically, this robot will be a 4 wheeled car that will be able to detect cars in front of it and change lanes and overtake that car.
i would also like the robot to be able to turn left and right.
i would also like it to be able to accelerate to different speeds.
i will be running parallel processes (the car will have multiple commands to complete at the same time).
what are some good wheels that i can use for this project (i am looking for something under $3 per wheel, but would like them to be rubber)?
what is a good uC for this project? (you said that i would only need one)
also, can you explain how a uC works...
how many processes can they generally run at the same time
(for example, i would like it to be able to change speed, turn, and do other tasks at the same time)? (simple terms please!)
what is a good micro-controller that is under $50?
how do i tell whether my sensors are analog or digital?
list of things connected to microcontroller...6 ir sensors1 sharp ir range sensors2 line following sensorsdc motorservo (controlling steering)
how much processing power will i need to do all of these tasks? will the arduino mega be enough?
how do i route the power from 5AA batteries to the sensors and motor (through the micrcontroller)?
what ports (i/o pins, pwm, etc.) do i need to plug in these sensors to?
i want the car to drive between two white lines... how do i do this? do i use line following sensors? do i need two sensors?
You don't say, so I'm assuming all these sensors are analog, meaning you'll need 9 ADC channels for sensors.You don't say, so I'm assuming the dc motor requires a couple PWM outputs (+ enable, + ).
