# Robot Simulator
Write a robot simulator.
A robot factory's test facility needs a program to verify robot movements.
The robots have three possible movements:
- turn right
- turn left
- advance
Robots are placed on a hypothetical infinite grid, facing a particular
direction (north, east, south, or west) at a set of {x,y} coordinates,
e.g., {3,8}, with coordinates increasing to the north and east.
The robot then 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 "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.
The Scala exercises assume an SBT project scheme. The exercise solution source
should be placed within the exercise directory/src/main/scala. The exercise
unit tests can be found within the exercise directory/src/test/scala.
To run the tests simply run the command `sbt test` in the exercise directory.
For more detailed info about the Scala track see the [help
page](http://exercism.io/languages/scala).
## Source
Inspired by an interview question at a famous company.
