Welcome to the Toy Robot Simulator!

This is a command-line program which simulates a robot moving on a table. The following commands are available:

• PLACE X,Y,(NORTH|EAST|SOUTH|WEST) - X and Y must be within table dimensions.
• MOVE - Moves the robot forward one square in the direction it's facing.
• LEFT - Turns the robot 90 degrees left.
• RIGHT - Turns the robot 90 degrees right.
• REPORT - Outputs the robot's current position on the table.
• CTRL+C - Exit.

Rules & Assumptions

• Robot must be given a valid PLACE command before any others will work.
• The origin (0,0) of the table is in the south-west corner.
• Empty input will be ignored.
• Invalid commands or invalid arguments to PLACE will output a corresponding "Invalid" message.

Extensibility

By having the Robot and Table as separate objects, a robot can be placed on different tables and a table can have multiple robots. Give robots a Gun object and a #shoot method, and this game can become Robot Wars!

Limitations

Currently the robot is only able to move on a Table. A way to improve the design would be to allow the robot to be placed on any type of object which has a grid layout.
