1: Start of by placing the robot on a square grid with dimensions of 5 X 5.
Use the following command to place the robot.
PLACE X,Y, F (F = NORTH SOUTH EAST or WEST)
2: Once the robot is placed, interact with it using the following commands.
MOVE – Moves the robot 1 unit to the direction it is facing.
LEFT – Rotates the robot to 90 degrees in the left direction.
RIGHT – Rotates the robot 90 degrees in the right direction.
REPORT – Queries the current stats of the robot.
EXIT – Close Toy Robot Simulator.
