# Robot Management

```
This guide is focused on explaining the purpose behind each game module. 
For a detailed documentation of the methods and attributes of the classes, 
check the doxygen documentation.

## System Overview

The robot system is in charge of communicating with the robot and sending commands to control its movement.

## RobotManager class

The `RobotManager` class defines the interface required for communication with a Robot Devastation robot.

The main functions of a `RobotManager` are:

* `moveForward()`: command the robot to move forward at the specified velocity.
* `turnLeft()`: command the robot to turn left at the specified velocity.
* `stopMovement()`: command the robot to stop.
* `tiltDown()`: command the robot to move the camera down at the specified velocity.
* `panLeft()` : command the robot to move the camera to the left at the specified velocity.
* `stopCameraMovement()`: command the camera to stop moving.

## YarpRobotManager class

`YarpRobotManager` is an implementation of the `RobotManager` interface using [YARP](http://www.yarp.it/) as middleware for communications with the robot.

## MockRobotManager class

`MockRobotManager` is an implementation of the `RobotManager` for unit testing purposes.

The `MockRobotManager` adds the following methods for testing:

* `isConnected()`: checks if the game is connected to the robot.
* `isEnabled()`: checks if the robot is enabled.
* `isMoving()`: check if the robot is moving.
* `getMovementDirection()`: returns the direction in which the robot is currently moving.
* `isCameraMoving()`: check is the camera is moving.
* `getCameraMovementDirection()`: returns the direction in which the camera is currently moving.
