Arduino Robot Serial Issues

Using Arduino IDE 1.x

I'm trying to run this sketch on my Arduino Robot, but am not receiving anything over Serial. The TX led not flashing

I'm pretty sure the sensor has been properly setup. Not sure what else to say.

Any ideas are much appreciated.

You could specify more about your setup. How are you powering the robot and how are you connecting it via serial.

I'm using a Windows 8.1 64 bit Laptop and Arduino 1.0.5-r2.

I'm using the USB cable supplied with the Robot to power it.
