Robot factory

Let's consolidate our knowledge of prototypes and constructors! This task has 3 parts.

The first part is to build base robot's constructor and its prototype according to the following requirements:

• BaseRobot function constructor takes name, weight, coords, chipVersion and sets them for his instances;
• BaseRobot prototype has methods goForward, goBack, goRight, goLeft, which can take step prop or move the robot by 1 in the appropriate direction in the case when step is undefined;
• BaseRobot prototype has method getInfo, which returns a string in the format Robot: %name%, Chip version: %chipVersion%, Weight: %weight%;

The second part is to build flying robots constructor and his prototype according to the following requirements:

• FlyingRobot prototype inherits BaseRobot prototype;
• FlyingRobot constructor takes name, weight, coords, chipVersion, and transmits them to BaseRobot constructor;
• FlyingRobot constructor sets z coordinate to coords object of his instances;
• FlyingRobot prototype has methods goUp and goDown, which can take step prop or move the robot by 1 in the z coordinate in the case when step is undefined;
• The instance of FlyingRobot can use all methods from BaseRobot and FlyingRobot prototypes;

The third part is to build delivery drone constructor and his prototype according to the following requirements:

• DeliveryDrone prototype inherits FlyingRobot prototype;
• DeliveryDrone constructor takes name, weight, coords, chipVersion, and transmits them to FlyingRobot constructor;
• DeliveryDrone constructor takes maxLoadWeight, currentLoad and sets it to his instances;
• DeliveryDrone prototype has method hookLoad, which saved the load object to currentLoad of DeliveryDrone instances if weight of cargo less than maxLoadWeight of drone;
• DeliveryDrone prototype has method unhookLoad, which sets initial value null to currentLoad;
• The instance of DeliveryDrone can use all methods of BaseRobot, FlyingRobot, DeliveryDrone prototypes;

Delivery Robot schema:

deliveryRobot {
  name: string
  weight: number
  chipVersion: number
  maxLoadWeight: number
  currentLoad: null || {
    weight: number
    description: string
  }
  coords: {
    x: number
    y: number
    z: number
  }
}
