Toy Robot Simulator

Description

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

• There are no other obstructions on the table surface.

• Application can read in commands of the following form:

  PLACE X,Y,F
  MOVE
  LEFT
  RIGHT
  REPORT
  

• 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.

• REPORT will announce the X,Y and F of the robot. This can be in any form, but standard output is sufficient.

• A robot that is not on the table can choose the ignore the MOVE, LEFT, RIGHT and REPORT commands.
