Install

npm install

Run tests:

npm run test

Written with a test first approach (TDD)

Start:

npm start

The UI will load at localhost:8080

The UI displays the black command entry box and the once initialised with a command e.g. 10 10 the red mars grid will display below.

Usage:

• Enter commands in the black command box followed by pressing enter. (pls see caveats below)
• Entering 10 10 (or other integers) and pressing enter will generate a grid.
• Then entering 1 1 N will creat a new robot at that location.
• Then entering the movement commands e.g. FFFRFLFF will move the robot and it will then output its location to the command box.
• you can have multiple robots but you can only move the last one added.
• you can move a robot multiple times.

Caveats

Most of the functionality was built but with a few caveats:

• You can only enter one command at a time into the command box. Sorry, copy and paste fail.
• If a command has a trailing space it won't register.
• New robots don't check for where lost robots fell off the world, so new robots can still get lost at the same place ( I guess they're off to find their friends ;) )
