You just need to replace the motor.set() with myRobot.Drive().

Here is your code with the replacements made. It compiles.

#include "WPILib.h"
#include "Vision/AxisCameraParams.h"

/**

 * The SimpleRobot class is the base of a robot application that will automatically call your
 * Autonomous and OperatorControl methods at the right time as controlled by the switches on
