Commands the robot

Whenever the robot is doing nothing it will send an HTTP request to the server /command.

That will returns JSON such as:

• {"command": "rotate", "value: -90/90/180, "audio": "file1.mp3"}
• {"command": "move"} // til the next point
• {"command": "sleep", "value": timeInSeconds}

When the robot detects an obstacle within 20cm, it stops and retrieves new instructions using /command?obstruction=true.
