Mars Rover Kata

Getting started

Create a new planet indicating the grid dimensions:

{:ok, mars} = MarsRover.Planet.start_link(10, 10)

Adding some obstacles in planet grid:

{:ok, {3, 1}} = MarsRover.Planet.add_obstacle(mars, 3, 1)

Create a new Rover indicating the landing coordinates and the initial facing direction (default is :n):

{:ok, rover} = MarsRover.Rover.start_link(mars, 1, 1, :s)

Send command to rover (f, b, l, r):

{:ok, {1, 10}} = MarsRover.Rover.commands(rover, "fffffffff")

MarsRover.Rover.commands/2 returns the final position coordinates after moving.

If rover hits an obstacle, MarsRover.Rover.commands/2 returns the obstacle position in planet grid

{:error, {:obstacle, {3, 1}}} = MarsRover.Rover.commands(rover, "bbbbbbbbblff")

You can get the current rover position coordinates using MarsRover.Planet.Rover.position/1:

{2, 1} = MarsRover.Rover.position(rover)
