Gamepad is an extended class for Joystick that I wrote for a few things that I wanted to change, and that is not the problem since I tried using Joystick class as well.

For the RobotDrive, you can also have left SpeedController and right SpeedController instead of PWMs.

I think it's something wrong in wiring. If I have just the drive motors in my code, it works fine. And if I have all the other motors except the drive motors, it works fine then also. But as soon as I include all the motors, everything stops working.

Thanks!
