Toy Robot simulator on a 4x4 table.

Placed at a position, it can turn right, left, move one step forward in the direction it is facing, and report the current position and direction it is facing.

The robot is smart enough not to jump off the edge if you say so.

cd ../into/the/directory
iex -S mix

iex> {:ok, robot} = ToyRobot.place(1, 1, :east))
iex> robot = robot |> ToyRobot.move
iex> robot |> ToyRobot.report
{2, 1, :east}
iex> robot = robot |> ToyRobot.right |> ToyRobot.move
iex> robot |> ToyRobot.report
{2, 0, :south}
