Robot Challenge

1. Task Requirements

   • Self- Determined Criteria
     • LIght
       • Display a smiley face at the end.
       • Display a sad face at the beginning.
     • Movement
       • Spin at the end.
     • Sound
       • Say "Well Done!" at the end.
       • Say "Welcome" at the beginning.
   • Prescribed Criteria
     • Follow a safe path to the exit.
       • Follow the black line on the mat.
       • When the robot senses green, turn left.
       • When the robot senses red, stop moving.
       • When the robot senses an obstacle, navigates around the edge.
     • Use sensor to identify any dangers or obstacles.
       • Use a distance sensor to detect an obstacle.
       • Use a force sensor to detect pressure if the robot hits an obstacle.
     • Use sensor(s) to avoid or manoeuvre any dangers or obstacles.
       • When an obstacle is detected, navigate around the hedge to avoid it and continue following the path.
       • When an obstacle is detected, move forward to push it away from the pathway.
     • Complete a room-specific challenge.
       • Navigate the hedge without touching it, then return to the pathway and keep following it until it reaches the exit.
       • Move the obstacle away from the pathway and reach the exit.

2. Spike Prime Robot

   • Distance Sensor
     • The Distance Sensor measures the distance to an object or surface using ultrasound.
       • It works by sending out high-frequency sound waves that bounce off any object in range, and measuring how long it takes to return to the sensor.
   • Colour Sensor
     • A Colour Sensor detects, measures, and identifies the colour of objects by analysing reflected or ambient light.
   • Motors
     • Large Motors
       • Large Motors provide high power and torque to drive wheels and move heavy loads.
     • Medium Motors
       • Medium Motors offer a compact, fast-responding design with precise control, ideal for driving smaller attachments and steering mechanisms.
   • Touch & Force Sensor
     • By detecting physical contact and pressure, the touch sensor captures environmental input to direct the robot's actions.
       • This condition prompts the robot to alter its function.
   • Rotation Sensor
     • The rotation sensor allows both motors to track their exact speed and position in real time for precise movement and feedback.

3. Coding Constructs

   • FOR Loop
     • A For Loop is used when it is known exact.ly how many times to go around the loop
       • FOR 3 steps MOVE forward ENDFOR
   • Arrays
     • It stores a collection of multiple items under a single variable name.
       • Let players = [Sofia, Connie, Macy] Let scores = [10, 20, 30]
   • IF
     • An IF statement runs a block of code only if a condition is true.
       • IF the robot senses green Then turn left
   • IF ELSE
     • An IF/ELSE statement adds a backup plan: it runs one block of code if the condition is true, and a different block of code if it is false
       • IF the robot senses green Then turn left ELSE follow the black line
   • WHILE Loop
     • A While Loop is used to repeat while a condition is true or false. These can be used as forever loops where required.
       • WHILE object distance GREATER THAN 5cm MOVE forward ENDWHILE
   • Variables
     • It stores, retrieves, and manipulates data in a computer's memory.
       • Age=14 player_name=Sofia
   • Loop
     • A loop is a programming construct that allows a section of code to be executed repeatedly.
       • Forever Repeat 10 Repeat until

4. Algorithm / Pseudocode constructs & language

   • Sequence
     • Sequence refers to a set of instruction that are processed one after the other.
       • 1. Preparation 2. Pack the bag 3. Put on the shoes 4. Open and close the door 5. Walk towards the school
   • Iteration/Repetition
     • Iteration is used when something is repeated, so anything where the program goes round in a loop.
       • FOR
         • FOR 3 steps MOVE forward ENDFOR
       • WHILE
         • WHILE object distance GREATER THAN 5cm MOVE forward ENDWHILE
   • Selection & Condition
     • A selection statement uses a condition to select which line of the program will be used next.
       • IF condition THEN Statements END IF
   • Assignment
     • Assignment is storing a value in a variable.
       • DECLARE player_name SET player_name TO Sofia

5. Planned responses / routes

   • Rockfall Challenge
     • Follow the path to the exit by pushing the obstacle out of the way
       • Colour Sensor
         • It measures light reflection to detect colour.
       • Distance Sensor
         • It measures the distance between the robot and an obstacle before the robot pushes.
   • Poison Ivy Challenge
     • Follow the path to the exit without touching the hedge/obstacle
       • Colour Sensor
         • It measures light reflection to detect color.
       • Distance Sensor
         • It measures the distance between the obstacle and the robot without touching it.
