Does the TX led on the transmitter blink or light up? Does the RX on the receiver do the same? If neither light up, then it could be your modules have a problem.

Hold up, your not going to send or receive with the serial monitor if the modules are attached to the normal Tx and RX pins. Your boards are set for hardware serial and not software serial like they should be. Move the jumpers on both boards. To send with the serial monitor, you need to first setup software serial on both boards and use pins 2 and 3. Then combine Serial.read with softSerial.write to send and use the reverse to receive.

Please note this is if you want to use the serial monitor to both send and receive, however you can have the transmitter set to normal hardware serial and use Serial.println("message"); but the receiver will need to be set to software serial regardless.

There is no L and R, there is Z and C, have another look at it.  Also you're not going to fit everything inside it, so you will need to use the cable.

There is a library you could use if you plan on just using the Nunchuck alone, but if you want to use both then you would need to get a USB host shield and bluetooth dongle. However if you use this Wii classic controller, it too has its own library and it is easy to set up.

Where is your receiving code?

Code:
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  if(Serial.available() > 0)
  {
    char c = Serial.read();
    if(c == '\n' || c == '\0') // look to see if newline char was sent or NULL char was sent
        Serial.println();
    else
        Serial.print(c);
  }
}

then the angle is positive, so i wanted the angle to be mapped from 0 to 90(or 180, but the bot cant move past 90) and say its falling backwards,
Ok, I see what you were doing now.

if (0 <= accelAngleX < 180)
For starters, this isn't proper format. It should be if(accelAngleX >= 0 && accelAngleX < 180) and when will accelAngleX be greater than 180? You really want to look to see if it is less then 90, if so map to pwmA, otherwise it is greater and so it should be map to pwmB.

Also your maps should be 0, 90 for pwmA and 90, 180 for pwmB.

Exact measurements, if you can.
878  Using Arduino / Project Guidance / Re: My 1st project: TIE Crawler from the Star Wars Expanded Universe on: February 03, 2014, 04:06:25 pm
Yea, well I think it is.

IR Vs. RF

That is difficult to say. Yes there are things better than others but they might not fit in the space you have to work with.
You have the tracks already? Did they come with any sprockets or gears?

In order to figure out what motors will work for you, you need to first make the model structure. Then see how much room you have left after you installed the tracks + gears/sprockets, and if possible get some test motors.

For the Arduino, you may want to get either a Nano, Micro, or Mini. (Preferably the 5 Volt Mini).
As far as a motor controller, try these.
One
Two

Or you can make your own motor controller with one of these, SN754410NE

I don't know anything about IR trans/receivers so I can't help you there, but you could maybe use a RF trans/receiver pair.

Your project is feasible but what is the 412 arduino shield, do you have a link?
882  Using Arduino / Project Guidance / Re: My 1st project: TIE Crawler from the Star Wars Expanded Universe on: February 02, 2014, 11:36:00 am
It a basic controller. Is it going to be red or are you going to make it aluminium too?

Yea, it could work. You could also make an aluminium skeletal structure too, but you will need to weld it together. How to Weld Aluminium
885  Using Arduino / Project Guidance / Re: My 1st project: TIE Crawler from the Star Wars Expanded Universe on: February 02, 2014, 10:04:00 am
You will need to make a skeletal structure and attach the aluminium pieces with screws, or you could weld everything and hope you don't make a mistake.

How much of it will be aluminium?
