Robotic oriented Arduino ESP8266 library and examples to control game robots and remote controls through a wifi server.

1. Both the robot and remote control connect to the wifi server.
2. They send their identifier (set with jumpers) to the server.
3. In response, the server accepts the devices into the network.
4. Now the devices are able to send and receive data.

• The remote control sends its joystick position and if it is clicked or not. The server forwards this information to the corresponding robot
• the robot sends a message to the server if it found an LED on the game board
• when the server accepts the LED detection , it sends a message to the robot which turns on its own LED
• after a while, the server tells the robot to turn off its LED

Depending on the devices jumpers, the remote controls and the robots have a specific ID: a robot ID ranges from 0 up to 3, a remote control ID ranges from 4 up to 7. Any joystick state message sent from the remote control of ID x to the server is forwarded as-is to the robot of ID x - 4.

• Remote control and robot discovery message to server:
  • "'Z' {ID}" whith {ID} from '0' up to '7' (eg. Z6)
• Server to each device:
  • 'ZV' to accept the join request
• Remote control joystick position and button press state to server:
  • If the joystick is pressed
    • "'Y' {strength}" with {strength} ranging from '0' up to '9'. It is the position of the joystick from left to right (eg. Y5, the joystick is at the middle position)
  • Else
    • "{direction} {strenght}" with {direction} ranging from 'A' up to 'X', 'A' is straight ahead. {strenght} ranges from '0' up '9', '0' when the joystick is at the center position. (eg. F9, the joystick is at the most right position).
• Robot to the server :
  • D1 when a LED is detected on the game board
• Server to the robot
  • 'ZD': turn your LED on
  • 'ZO': turnb your LED off
