Year 9 - Item 1

1. Algorithm Constructs

   • Iteration
     • Iteration is also called repetition and is used when something is repeated, so anything where the program goes round in a loop.
       • FOR loop, WHILE loop
   • Selection and condition
     • A selection statement uses a condition to select which line of the program will be used next
       • IF, THEN, ENDIF
   • Assignment
     • Assignment is storing a value in a variable
       • SET Name TO 5
   • Sequence
     • Sequence refers to a set of instructions that are processed one after the other
       • READ width of rectangle READ length of rectangle COMPUTE area as length times width

2. Spike Prime Robot

   • Motors
     • Makes the robot move
   • Distance Sensor
     • Senses objects in front of the robot
   • Colour sensor
     • detects colours
   • Touch sensor
     • Can assist the robot in moving objects

3. Task requirements

   • Prescribed Criteria
     • Follow a safe path to the exit.
       • The robot will follow the black line using the colour sensor to the exit
       • The robot will turn left at green corners using the colour sensor
     • Use sensor to identify any dangers or obstacles.
       • The robot will use the distance sensor to sense dangers or obstacles that are 5cm away
       • The robot will display a heart on the LED panel when dangers or obstacles are sensed by the distance sensor
     • Use sensor(s) to avoid or manoeuvre any dangers or obstacles.
       • The touch sensor will be used to manoeuvre any danger or obstacles out of the way
       • The robot will increase speed to manoeuvre the danger or obstacle out of the way
     • Complete a room-specific challenge.
       • The obstacle is moved out of the way
       • The challenge and track are completed
   • Self-Determined
     • The robot will display “done” on the screen when it finishes the challenge
       • “Done” will be displayed on the LED panel
       • Done” will be displayed when the colour sensor senses red

4. Code Constructs

   • IF Statement
     • Selection statements check whether a condition is true
       • START IF winning numbers THEN OUTPUT prize money ELSE OUTPUT message 'Not Today' ENDIF
   • FOR Loop
     • A FOR loop is used when it is known exactly how many times to go round the loop
       • FOR 3 steps MOVE forward ENDFOR
   • Other code constructs

5. Planned Response

   • Poison Ivy challenge
     • Go around obstracle
       • Use touch sensor to move around obstacle
   • Rockfall challenge
     • Push obstacle out of the way
       • Push obstacle then return
