Year 9 Item 1

1. Task Requirements

   • Prescribed Criteria
     • Follow a safe path to the exit.
       • Do not trail off the set path
       • Use code to follow the line
       • Loop the code until the goal is reached
     • Use sensor to identify any dangers or obstacles.
       • Use code to avoid objects
       • Use colour sensor to turn when green turnpoints are detected
       • Use a sensor code that follows up with a process
     • Use sensor(s) to avoid or maneuver any dangers or obstacles.
       • Use a distance sensor to detect the object
       • When the distance is detected move around the object
       • Redirect the robot's position to keep line following the path
     • Complete a room-specific challenge.
       • Avoid the obstacle
       • Make it to the ending pad.\
       • Do not trail off set path
   • Self-Determined Criteria
     • When the robot passes the obstacle, play a sound indicating that the challenge has been overcome, also displaying the text ‘Triumph!’ on the robot’s LED panel.
       • Add code that plays the sound
       • Follow up with code after the code to move around the obstacle
       • Add code displaying the text on the robot's LED panel

2. Algorithm Constructs

   • Selection and Condition
     • Chooses actions using IF statements and checks whether something is true or false.
   • Iteration
     • Repeats instructions using loops such as FOR or WHILE.
   • Assignment
     • Gives values to variables.
   • Sequence
     • instructions happen in a specific order.

3. Spike Prime Robot

   • Motors
     • Allow the robot to move and change directions at desired speed, rotation and intervals
   • Distance Sensor
     • Senses distance between an above ground surface/structure and the sensor
   • Other Sensors
     • The press sensor, which detects how much force is on the protruding axel at the front of the robot
     • The color sensor, which can sense a total of 8 colours at the sensor, which is located under the robot and in front of its head wheels

4. Planned Response

   • Poison Ivy Challenge
     • Explanation Of Challenge
       • Follow the black path through the room to the exit. But beware, a heavy rock has fallen from an archway and is blocking part of the path. 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.
   • Rockfall Challenge
     • Explanation Of Challenge
       • Follow the black path through the room to the exit. But beware, a hedge covered in poison ivy is blocking part of the path. Do not touch the hedge! Navigate around the hedge and back onto the black path to escape by reaching the exit.

5. Code Constructs

   • IF Statement
     • The IF statement allows the robot to make decisions based on what its sensors detect.
   • FOR Loop
     • The FOR loop is used to repeat a set of instructions a specific number of times. In a robot program, this can be used for movements such as moving forward for a certain number of rotations or repeating an action.
   • Other Code Constructs
     • FOREVER Loop
