Error with Compiling ... multiple definition

Trying to get the BlueTooth Smart Car code to work. Keep getting the error below and not sure how to resolve. Any help? Thanks in advance.

Link to the code

Arduino: 1.6.5 (Windows 7), Board: "Arduino/Genuino Uno"

Using library Robot IR Remote in folder: C:\Users\Desktop\ARDUINO\arduino-1.6.5-r5\libraries\RobotIRremote

Using library Servo in folder: C:\Users\gthreadgill\Desktop\ARDUINO\arduino-1.6.5-r5\libraries\Servo

Error compiling.

You’ll get a lot more help if you post the code between code tags. Without it all I can tell you is exactly what the compiler told you, you have irrecv defined multiple times and that’s not allowed.

Do you have an Arduino robot? If not, delete the code that causes the error. That crappy robot was just about the worst thing that the Arduino team has come up with, involving the least thinking about the impact of usurping an already widely used name.

Thank you for the quick responses ... trying to get this damn car working for my son's class tomorrow.
