1. Planned Response

   • Posion ivy challange
     • Robot must detect the poison ivy (the obstaclse), navagaite around it without making any contact with it. and return to the black path and reach the exit
       • Use distance sensor to detect the object, it should be able to return back to the black line after navagating around it.

2. Spike Prime Robot

   • Other Sensors
     • Colour sensor can detect the black path and help the robot stay on trach
     • Use colour sensor to detect the blackline and follow it
   • Distance Sensors
     • Detect obstacles by mesuaring the distance between the robot on the object.
       • If the robot is within 15cm, the robot stops and takes action
   • Motors
     • Drive the robot forward, backwards and turn it to navigate the escape room
       • Use motors to move forward, turn left/right and revers.

3. Task Requirements

   • Prescribed Criteria
     • PC4
       • Navagatie around the object without touching it
       • Return to the blackpath and reach the exit
       • Detect the posion ivy
     • PC3
       • Robot changes its movment when an obstacle is detected
       • Robot returns to the black line.
       • Robot carefully moved around without touch the box or interferring with other stuff
     • PC2
       • Use the touch sensor to detect the obstacle
       • Sensor provides infromation about the obstacle
       • Robot responds when an obstacle is detected
     • PC1
       • Robot follows that black path
       • Robot reaches the exit
       • Robot does not unfollow the black line and start spinning from the white.
   • Self Determined Criteria
     • SDC 2
       • Robot avoids unnecessary movments.
       • Robot completes the course within a reasonable time.
       • Robot completes the course with minimial errors
     • SDC1
       • Robot stays as close as possible with the black line
       • Robot makes accurate turns
       • Robot reaches the exit consistently

4. Code Constructs

   • FOR Loop
     • Repeats a set of instructions a specfic amount of time
       • For 3 rotations, than move robot forward.
   • IF Statement
     • Checks, and preform action if its true.
       • If the distance sensor detects and obstacle, it will first stop moving than find its way around it
   • Other Code Construct

5. Algorithim Construct

   • Iteration
     • Repeats movment or sensor instructions while the robot completes its route
   • Selection and Condition
     • Make a decsion based on weather a condtion is true or false
       • IF the touch sensor detects and obstacle, it should be able to navagatie around it,
   • Assigment
     • Set speed to 50 percent
       • Robot moves faster by 60 percent
   • Sequence
     • Move forward, Turn right, Turn left.
       • Instructions are completed in a specfic order from beggening to end
