Mars Rover Python

This project implements the classic Mars Rover challenge in Python, following a modular design inspired by hexagonal architecture (Ports and Adapters).

Currently, only Phase 1 (core domain and main use case) is implemented.
Phases 2 to 4 are planned and will be developed later.

🛰 Challenge Description

NASA has deployed a fleet of robotic rovers on a rectangular plateau on Mars.
Each rover's state consists of:

• Its position (X, Y)
• Its compass heading (N, S, E, W)

Commands:

• L → turn left 90°
• R → turn right 90°
• M → move forward one grid point in the direction it is currently facing.

Rules:

• The plateau is represented as a grid.
  • By default: 10×10 (valid coordinates from 0 to width-1 / height-1).
  • The origin (0,0) is at the bottom-left corner.
• If a move would take the rover outside the grid, it is ignored.
• Obstacles can be placed on the plateau.
  • If a rover encounters an obstacle, it stops immediately and outputs a result prefixed with O: (status "obstacle").

📥 Input Format (Phase 1 example)

For Phase 1, input is handled programmatically (no CLI yet).
A plateau, initial position, heading, and command sequence are passed to the execute() function.

Example:

plateau = Plateau(5, 5, obstacles=set())
start_position = Position(1, 2)
heading = Direction.N
commands = "LMLMLMLMM"

📤 Expected Output

The program returns a dictionary with:

{
  "status": "ok" | "obstacle",
  "x": <final_x>,
  "y": <final_y>,
  "heading": "N" | "E" | "S" | "W"
}
