Mars Rover Kata

Introduction

We are sending a rover to Mars and we need to program its movements so that

we can send it commands from Earth.

Basic Information

The rover will have initial starting point (x,y) coordinates (i.e. 0,0)

The rover will have an initial direction (N,E,S,W) to where it is facing

The rover is on a 10 x 10 grid

Implement commands that go forward and backward (f,b)

Implement commands to turn the rover left or right (l,r). The rover just

change the direction it is facing when the user sets this command.

It won't move right or left automatically. To make it change its position,

the user needs to specify the change of direction and then the actual movement.

Iteration 1:-

1) Create an object to represent the rover that has position and

direction attributes

2) Create a grid using arrays (hint: do a google search for two-dimensional

arrays).

3) Write functions for the various commands

4) Try to call some of those functions and display the new position of

the rover.

Iteration 2:-

We want to be able to send a series of commands to the rover and execute

them in sequence.

We will send an array of character commands, which can include:

f for go forward

b for go back

r for turn right*

l for turn left*

The rover just change its direction when we use this command: r and l.

It won't move right or left automatically. To make it go right or left,

the user needs to specify the change of direction and then the actual movement.

So we should be able to tell the rover, for example, ‘fffrfflfffbb’

and it would execute those movements and provide us with its new position.

Furthermore, we need to make sure that the rover never goes off the grid

but rather, wraps from one edge of the grid to another

(planets are spheres after all)

Bonus:

In your 10 x 10 grid, place some obstacles that the rover cannot cross or

land on. Implement obstacle detection. The rover should execute the given

commands until it reaches an obstacle, then stop at the last possible position

and report the obstacle.

Extra hardcore super bonus:

Our rover is lonely! We need to send another one that can roam on the same

grid and execute the same commands. Make sure the rovers don’t bump

into each other.
