Make sure you write the code inside the makeDecisionForTask2() function in this task! • In this task, the exit may be to the left or to the right of the robot • In the previous task, the exit can only be on the right so this task is a little more difficult to do than the previous one Previously, the robot searches for the exit by turning to the right only • Now, in this task, rather than just the right hand side, you also need to make the robot search the left hand side • You can extend the idea from the previous task to something like this: Step 1. The robot moves north until there is a wall above a If the robot sees a wall above, it turns east (go to step 2) and searches for the exit Step 2. The robot moves east, searches for the exit until there is a wall on the east a If the exit is found (ie. no wall above), the robot will go north (back to step 1) and move to the exit b. If the robot sees a wall on the east, it turns around (go to step 3) and searches for the exit Step 3. The robot moves west and searches tor the exit a. If the exit is found (ie. no wall above), the robot will go north (back to step 1) and move to the exit • You need to add one more state which asks the robot to move west, with the appropriate transitions Then, the above logic can be represented by the following state diagram Action: NONE Condition: If cannot move north Action: NORTH Go north Go east Action: EAST Action: NONE Condition: if connot move east Action: NONE Condition: If can move north Action: NONE Condition: If can move north Go west Action: WEST • In this task, you need to write the code to put the above diagram in the makeDecisionForTask2() function • The state of the diagram is then stored inside the currentStateForTask2 variable • You can use the "NEXT STEP" button below to visualize each step the robot should make
