You are provided with a file robot.py (see attached file later). This file contains code that implements a very basic Robot object. It has a constructor, getter and setter methods. Take a look at the Robot class and familiarize yourself with those methods.

Your task is to write the main routine that creates a Robot object, prints the initial state of the object, moves the Robot forward some distance, displays the current state of the Robot after moving forward, charges the Robot's battery and then displays the state of the Robot after charging its battery.

self.__batteryLevel = self.__batteryLevel * (1.0 - distance/(distance + 1.0))

# helper methods def getCurrentSpeed(self):

speed = math.pow(self.__batteryLevel, 2.0) * 2.0

return speed

time = self.__distanceTraveled / self.getCurrentSpeed()
