Year 9 Digital Solutions Item 1

1. Criteria

   • Prescribed critera
     • Follow a safe path to the exit.
       • Follow the black path line on the mat
       • When robot senses green, turn left
       • When robot senses red, stop; the task has finished.
     • Use sensor to identify any dangers or obstacles.
       • Use colour sensor to detect green ivy hedge
       • Use distance or force sensor to detect obstacles
     • Use sensor(s) to avoid or manoeuver any dangers or obstacles.
       • Constantly monitor colour or distance sensor to avoid failing task
       • Program peripherals to avoid obstacles
     • Create a room-specific challenge.
       • Poison ivy challenge
         • Follow black line path to end of mat. Do not touch green hedges - they are covered in poison ivy.
       • Rock Fall challenge
         • Follow black line path to end of mat. There is an obstacle that must be pushed out of the way.
   • Self-determined criteria
     • Movement
       • Do a 360 spin
     • Sound
       • Meow
     • Light
       • Write "Mission complete"

2. Lego SPIKE Prime

   • Sensors
     • Colour
       • Object underneath robot enters light sensor
     • Distance
       • Distance sensors use ultrasonic echolocation to measure distance
     • Pressure
       • Newtons
       • Uses a reverse Newton Spring Metre to measure force
   • Movement
     • Motors
       • Connect to the Brick
       • Set movement speed and motors
       • D+C

3. Coding constructs

   • Variables
     • Predetermined phrases or symbols that represent a value
       • n = 5
       • x = 20
   • FOR
     • Repeats a sequence until condition is met
       • FOR i = 5, DO...
   • WHILE
     • Repeats a sequence while a condition is met
       • WHILE TRUE DO
   • IF
     • A sequence that activates when a condition is met
       • IF playerLevel IS EQUAL TO 5 THEN...
   • ELSE
     • Performs a sequence when a condition is not met
       • IF... THEN... ELSE...
   • IS EQUAL TO
     • A relationship between two variables that state they have the same value
       • IF x IS EQUAL TO 5 THEN...

4. Algorithm Constructs

   • Sequence
     • A set of instructions that are processed one after the other
       • 1. Put toothpaste on toothbrush 2. Use toothbrush to clean teeth 3. Rinse mouth and toothbrush
   • Assignment
     • Storing a value inside a variable
       • Let x = 10
   • Selection & Condition
     • Programs that are executed if conditions are met
       • IF x = 10 THEN...
   • Iteration
     • Used when something is repeated
       • while true do...

5. Planned Responses

   • Poison Ivy
     • Follow the black path through the room to the exit. Do not touch the hedge! Navigate around the hedge and back onto the black path to escape by reaching the exit.
       • Colour sensor
       • Selected
       • Motors
   • Rock Fall
     • Follow the black path through the room to the exit. Move the rock from the path! Clear the rock out of the way and then return to the path to escape by reaching the exit.
       • Distance sensor
       • Motors
