The first assignment for the Programming "Things" module in my final year.

This involved us programming a small Zumo robot with an arduino board, ultrasonic sensor and xBee communications board to navigate a maze of corridors and rooms, imitating a search and rescue robot. It must be able to autonomously navigate corridors, scan rooms and return back through the building by itself.

'p' - Starts robot after calibration process is over.

Spacebar - Stops robot carrying on with corridor behaviour.

's' - Stops robot carrying on with corridor behaviour.

'R' - Notify the robot it's changing to room state.

'C' - Notify the robot it's changing to corridor state.

'w' - Moves robot forward.

'a' - Turns robot to the left slightly.

'd' - Turns robot to the right slightly.

's' - Either stops the robot (if moving forward) or puts it in reverse.

'9' - Turns robot 90 degrees to the left.

'0' - Turns robot 90 degrees to the right.

'C' - Notify the robot it's changing to corridor state.

'R' - Notify the robot it's changing to room state.

'l' - Once notified of a state change, tells robot it's moving to the left.

'r' - Once notified of a state change, tells robot it's moving to the right.
