Assessment

1. Task requirements

   • Prescribed criteria
     • Follow a safe path to the exit
       • Requirements
         • When the robot senses black and white
           • Follow the black line on the mat
         • When the robot senses green
           • Turn left
         • When the robot senses an obstacle
           • Use distance sensor to manoeuvre around
         • When the robot senses red
           • Course is completed
     • Use sensor to identify any dangers or obstacles
       • Distance sensor is used to identify any obstacles
     • Use sensor(s) to avoid or manoeuvre any dangers or obstacles
       • Distance sensor is used to avoid ob
     • Complete a room-specific challenge
       • Use sensors to navigate around the course and obstacles
   • Self determined criteria
     • Light
       • Display heart at the beginning
     • Sound
       • Play car horn when obstacle is sensed
       • Play tada when course is completed
     • Movement
       • Spins twice once completed course

2. Spike prime robot

   • Motors
     • For example, set movement motors to C + D
   • Distance sensor
     • For example, distance sensor senses obstacle ahead, robot stops for 3 seconds
   • Colour sensor
     • For example, when sensed red, stop
   • Force sensor
     • For example, accelerate to 100% push obstacles out of the way using force sensor

3. Coding constucts

   • Arrays
     • An array is a numbered list that stores multiple pieces of data together under a single variable name.
       • Egg carton: Stores 12 eggs, if you want egg 10, you take egg_carton10
   • Variables
     • You give the box a name (the label) and put a piece of data inside it (the value).
       • Example: x=3
   • IF
     • Used in coding that tells a program to run a specific block of code if a condition is true.
       • IF it rains then we will bring an umbrella
   • IF ELSE
     • Used in coding that tells a program to run a specific block of code if a condition is true, and a different block of code if that condition is false
       • Example: IF it is raining outside, THEN bring an umbrella. ELSE, THEN wear sunglasses instead.
   • FOR loop
     • Programming tool used to repeat a block of code a specific number of times or go through a list of items one by one. It stops automatically when it finishes the list or reaches a set limit.
       • Do 5 jumping jacks. Repeat the code 5 times until all jumps are completed. Once completed it stops.
   • WHILE loop
     • Repeats a block of code over and over as long as a specific condition stays true.
       • WHILE it is raining, keep holding your umbrella." The moment the rain stops (the condition becomes false), you put the umbrella away (the loop ends)

4. Algorithm constructs/pseudocode

   • Sequence
     • Instructions in an algorithm, that are processed one after the other. following a linear order from top to bottom
       • 1) Put toothpaste on the toothbrush. 2) Clean your teeth with the brush. 3) Rinse your mouth and the toothbrush.
   • Assignment
     • Assignment is to store a value in a variable.
   • Iteration
     • The process of repeating a specific set of steps or instructions over and over again until a specific goal or stopping condition is met. Known as the 'loop'.
       • Making small adjustments and trying again based on what you learned last time.
   • Selection and condition
     • A decision-making part of an algorithm that lets the program choose different paths based on a condition, which is a test that results in either true or false.
       • Condition: Is the customer's age under 12? Selection: If the answer is yes, they get a discounted child ticket. If the answer is no, they pay full price.

5. Planned responses

   • Poison Ivy challenge
     • Follow the path to the exit without touching the hedge/obstacle
       • Distance sensor
         • Used to identify obstacles and to avoid them
       • Colour sensor
         • Used to follow the black line and the path throughout. When sense green turn left and when sensed red, course is completed
     • This challenge was chosen
   • Rock Fall
     • Follow the path to the exit by pushing the obstacle out of the way
       • Distance sensor
         • Used to identify obstacle
       • Colour sensor
         • follow the black line and the path throughout. When sense green turn left and when sensed red, course is completed
       • Force sensor
         • Accelerate to speed 100% to push the obstacle out of the way
