The app on the phone connected to the game controllers says:

The last line is the key. The PushBot op modes require that you have several motors defined in your configuration file which you created on the robot. Two of the motors are called "left_drive" and "right_drive" and you don't have either. The build guide at
http://www.usfirst.org/uploadedFiles...uild-Guide.pdf covers this starting at about page 158. The screen showing the missing drive motors is on page 168. The description of the other missing motor, "left_arm" is on page 171. You may not have gone through these steps.
It's possible you did go through these steps, but then something went wrong. Specifically,
a) you didn't save the configuration file, or
b) the configuration file isn't the active one, or
c) you erased the configuration file
In any case, if you go through the steps from pages 158 through 179, you should be good to go.
