The robots have three possible movements:
- turn right
- turn left
- advance
The robot when receives a number of instructions, at which point the testing facility verifies the robot's new position, and in which direction it is pointing.
The letter-string instruction "RAALAL" means:
- Turn right
- Advance twice
- Turn left
- Advance once
- Turn left yet again
Say a robot starts at {7, 3} facing north. Then running this stream of instructions should leave it at {9, 4} facing west.
