Toy Ruby Robot Simulator

The application is a simulation of a toy robot moving on a square tabletop, of dimensions 5 units x 5 units.

Rules:

• The robot is free to roam around the surface of the table, but must be prevented from falling to destruction.
• Any movement that would result in the robot falling from the table must be prevented, however further valid movement commands must still be allowed.
• PLACE will put the toy robot on the table in position X,Y and facing NORTH, SOUTH, EAST or WEST.
• The origin (0,0) can be considered to be the SOUTH WEST most corner.
• The first valid command to the robot is a PLACE command, after that, any sequence of commands may be issued, in any order, including another PLACE command. The application should discard all commands in the sequence until a valid PLACE command has been executed.
• MOVE will move the toy robot one unit forward in the direction it is currently facing.
• LEFT and RIGHT will rotate the robot 90 degrees in the specified direction without changing the position of the robot.

Requirements:

• Ruby 2.0.0
• Rspec 2.14.1
