The interface and API require that a starting instruction and at least one move/turn are specified.
The leftmost column should be used to specify a sequence of instructions. This column is divided into two sections: Start and Moves/Turns.
To specify a starting instruction (Start Section):
- Select the starting direction from the dropdown labeled Direction
- Use the Steps number field to specify the number of steps to be taken in the specified direction
To Add Moves/Turns (Moves/Turns Section):
- Select the move/turn from the dropdown in the Moves/Turns section
- Enter the frequency of the move in the number field labeled Frequency and click the Add button. The specified instruction and its frequency will be added to the table in the middle column. Several move/turn instructions can be added this way.
Once the desired starting position and steps have been specified, clicking on the Execute button sends the sequence to the backend. The backend returns the updated position and direction which the frontend uses to render the position and direction of the robot in the grid in the rightmost column. The Reset button can be used to reset the starting position clear already specified steps.
The application requires Java 11 and an internet connection (as external static resources are referenced).
- It is assumed that the instruction # EAST means to move # STEPS to the EAST. For example: 3 EAST means move 3 steps in the direction of the EAST.
- The robot's starting position is always the cell [0,0] in the top left corner
- An execution order must include a starting instruction and at least one other instruction
