Year 9- Digital Technologies

1. Coding Constructs

   • IF and THEN Statement
     • Key pseudocode terms that activate a response when the condition is met.
       • Example: IF colour sensor detects the colour black THEN rotate 75 Degrees
   • WHILE Loop
     • A key pseudocode term that remains active whilst the condition remains met.
       • WHILE colour sensor is white: Start turning left 45 Degrees, display '0' image.
   • REPEAT UNTIL Loop
     • A key pseudocode term that repetitively activates a response until the condition is satisfied.
       • Example: REPEAT UNTIL touch sensor is pressed: Present :) image, activate '8-Bit' sound effect
   • GREATER/LESS THAN Statement
     • These are key pseudocode terms that activates a response when the condition of value/quantities remains met.
       • Example: IF distance sensor is LESS THAN 35 cm THEN: rotate 180 degrees, start moving forward for 35 cm.
   • Variables and values
     • General programming elements used in setting to shape overall function, provided with a quantity.
       • Example: DECLARE movement speed, SET movement speed to 25%

2. Algorithm Constructs

   • Sequence
     • A component that refers to the orderly structure of instructions set
       • Example: When Program starts, (FOREVER) IF colour sensor detects black THEN: turn 85 degrees left ELSE: turn 85 degrees right
   • Assignment
     • A component that refers to the positioing of variable and their values
       • Example: DECLARE motor wheel size, SET motor wheel size to 17.5cm
   • Iteration
     • A component that mainly regards the repetition, or loop, of a certain response.
       • Example: (FOREVER) Rotate motor C left 90 Degrees, start moving forward 22 cm, rotate motor C left 90 degrees...
   • Selection/Condition
     • A component that regards the use of conditions and the following responses directed.
       • Example: IF distance sensor is GREATER THAN 50cm THEN: Activate 'Applause' sound effect ELSE: display :( image

3. Spike Prime Robot

   • Colour Sensor
     • A sensor that notably detects the density of environmental colours
       • IF colour sensor detects green, rotate C motor right 60 Degrees
   • Distance Sensor
     • The Distance Sensor detects a certain distance from an obstruction
       • IF distance sensor is LESS THAN 35cm, start moving backwards display '>' image.
   • Touch Sensor
     • A sensor of the Spike Prime Robot that detects and applies force.
       • WHILE touch sensor is pressed, activate 'Cat meow' sound effect, reduce speed to 10%.
   • Motors
     • two motors of the robot mainly controlling movement.
       • (Activate C + D motor), rotate C motor left 110 Degrees, rotate D left 15 Degrees

4. Planned Response

   • Rockfall Challenge
     • Navigate the robot by following the black line, ensuring that the "boulder" is forced aside to continue to the end
       • Establish the standard line following coding to navigate around the course and apply use of the touch sensor to push aside the obstruction
   • Poison Ivy Challenge
     • Direct the robot through the course's black line and program a response to travel around the "poison ivy" to reach the end
       • Position the line following coding to travel through the course and install the distance sensor with turning codes to travel around the obstruction
       • This is the selected challenge

5. Task Requirements

   • Prescribed Criteria
     • Follow a safe path to the exit.
       • Apply line following coding
       • Implement proper turn coding.
       • Establish appropriate use of sensors
     • Use sensor to identify any dangers or obstacles.
       • Apply the appropriate, suitable use of sensors
       • Ensure that sensor coding is correctly viable and acceptable
       • Investigate if sensor responses align with coding
     • Use sensor(s) to avoid or manoeuvre any dangers or obstacles.
       • Ensure Spike Prime Robot is appropriately positioned with sensor function.
       • Trial what sensor coding fits with the conditions.
       • Ensure that sensor coding application is not 'overwhelmed' with others
     • Complete a room-specific challenges
       • Select and understand what the Spike Prime Robot challenge is.
       • Apply existing coding knowledge to navigate through course
       • Ensure implemented coding appears not over-complex
   • Self-Determined Criteria
     • Structurally organise coding to suit programming needs
       • Ensure coding includes standard, construct features
       • Properly position where each coding should be activated when
       • Do not overlap certain coding features with others to ensure efficient response
     • Ensure accounted sensors function properly
       • Inspect sensors are installed approrpiately
       • Observe how sensors operate
       • Does activity in sensors align with coding?
     • Apply additional coding effects to challenge
       • Install sound and light coding among the program
       • Ensure that added coding is not creating difficulty
       • Create a unique 'celebration' response at the end
