Mars Rover's kata in Kotlin
A Kotlin implementation of the Mars Rover's Kata.
Kata Description
Main features
- Display the Mars Rover's movements on a grid
- The Mars rover can receive four different commands:
- Move Forward
- Move Backward
- Rotate Right
- Rotate Left
- The grid is squared and its size is configurable
- The grid may contains rocks
- If the rover encounters a rock while performing a move, it should notify Houston and stop.
Mars rover to Houston : Mission aborted STOP. Rocks on the route STOP. Houston Do you copy ? OVER.
Additional features
- Generate random maps (random rocks coordinates, random rover initial coordinates)
- Set a random target on the map
- If the rover reaches the target, it should notify Houston and stop.
Mars rover to Houston : Mission achieved OVER. Houston to Mars rover : Well played Mars Rover STOP. Congratulations OVER AND OUT.")
- Given the rover initial coordinates, rocks coordinates and target coordinates, compute its route (see GIF above)
Disclamers
- I tried to rely on functions rather than classes
- I am just starting to look into functionnal programming so the result might not be very conclusive !
- The
computeRoutealgorithm is not really clever (it does not always find a path and when it does it does not necessarily find the shortest path). It has been developed empirically just for fun :)- It is property-based tested
- It tried to use some currying (might not be very conclusive either !)
