Year 9 - Item 1

1. Code Costructs

   • Other Code Constructs
   • FOR Loop
     • A FOR loop makes the robot perform an action for a certain amount of times.
       • SPIN around in circles FOR 20 times
   • IF statement
     • An IF statement is a selection with a condition and only if the condition is met can the robot perform a specific task.
       • IF robot is 4cm away from object THEN turn right

2. Task Requirements

   • Prescribed Criteria
     • Follow a safe path to the exit
       • Use line following sensors to keep the robot on the path
       • Use backup sensors to avoid any dangers or obstacles
       • Robot shall not crash into any obstacles blocking its path
     • Use sensor to identify obstacles or dangers
       • Use distance sensor to avoid crashing into any obstacles
       • Use touch sensor to make robot stop if pressure detected
     • Use sensors to avoid or manoeuvre all dangers and obstacles
       • Use distance and colour sensor to stay on path and detect dangers or obstacles and avoid them
       • Use touch sensor as a backup to detect pressure and stop to avoid crashing
       • The robot must solely rely on sensors rather than manual adjustments
     • Complete a room specific challenge
       • Successfully push the object out of the way and regain the course
       • The challenge was complete

3. Planned Response

   • Rockfall Challenge
     • In Rockfall the robot must complete the course and push the obstacle out of the way
       • The yellow path always makes sure that the robot checks left and right to stay on the path and identify the green marker that indicates a turning point. The robot will use the touch sensor to detect the pressure and speed up and push the obstacle out of the way and then get back on path to continue the safe black path to the end. This will be for the Rockfall challenge.
   • Poison Ivy Challenge
     • Poision Ivy challenge is completeing the entire course without touching the obstacle
       • The pink/red path always makes sure that the robot checks left and right to stay on the path and identify the green marker that indicates a turning point. The robot will use the distance sensor to detect the obstacle and make a square like formation to manoeuvre around it. Once it manoeuvres around the obstacle or box it will go back on to the path to continue the rest of the challenge/track. This will be the path for the Posion Ivy Challenge

4. Spike Prime Robot

   • Motors
     • The motors are to make the robot move forward, backwards, left, and right
   • Distance Sensor
     • The distance sensor is to detect objects without touching them
   • Other Sensors
     • There is also a colour sensor and a touch sensor to detect colour and pressure

5. Algorithm Constructs

   • Sequence
     • Set of instructions that are processed in a specific order
       • TURN on motors THEN turn left
   • Assignment
     • Assignment is basically the task of the robot
       • SUccessfully complete challenge without leaving path
   • Selection & Condition
     • this is when a certain thing happens on a certain condition but if that condition has not been met the specific task will not be completed
       • IF robot is 4cm away from object THEN turn right ELSE turn left
   • Iteration
     • Iteration is basically repeating something
       • REPEAT turning left

6. Self-Determined Criteria

   • Robot must express when challenge is complete
     • Robot must put happy face when challenge has been successfully completed
     • Robot must say “Complete” once challenge has been complete
