robots-challenge

About

This application has been created in order to explore Mars territory at its most by using robots! It is possible to feed the application with the size of the grid that you would like to explore, robots coordinates and instructions. Enjoy!

Prerequisites

Install Python 3 and pyenv.

• Install pyenv:

  curl https://pyenv.run | bash

  Caveat:

  • Remember to add the final lines printed by the previous command in your rc file (.bashrc/.zshrc)

Setup environment

cd path/to/robots-challenge/
pyenv install 3.6.12
pyenv virtualenv 3.6.12 robots

Activate the virtualenv:

source activate robots

Run the app

python main.py

Fill the file robots_guide.in.md with the proper input data in the following format:

5 3
1 1 E
RFRFRFRF
3 2 N
FRRFLLFFRRFLL
0 3 W
LLFFFLFLFL

Sample output for the above input:

*** Welcome to the Mars Robots Guide! ***

Here are the computed outputs:

(1, 1, 'E')
(3, 3, 'N') LOST
(2, 3, 'S')

The first line of input is the upper-right coordinates of the rectangular world, the lower-left coordinates are assumed to be 0, 0. The remaining input consists of a sequence of robot positions and instructions (two lines per robot). A position consists of two integers specifying the initial coordinates of the robot and an orientation (N, S, E, W), all separated by whitespace on one line. A robot instruction is a string of the letters “L”, “R”, and “F” on one line.

Testing

Install the necessary dependencies and run the tests:

pip install -r requirements.txt
py.test -s --verbose

Coverage
