Robotics challenge

1. Problems

   • Button might not work
     • solution
       • change your robot
   • The mat might be dirty so it will be hard to detect the black line
     • Solution
       • change to colour sensor
       • increase or decrease your light value so that it matches the black line
   • the wires on each robot might be different
     • solution
       • move the wires so that they match your code
       • change your code so that it matches the wire
   • light sensor might miss the black line
     • solution
       • change the speed at which the robot is moving at

2. task requirements

   • Prescribed criteria 1: Follow the path.
     • - Can turn smoothly when faced with a curved line
     • - Can turn left around corners without getting stuck
     • - Can turn right around corners without getting stuck.
   • Prescribed criteria 2: Detect and navigate around movable objects
     • - Can detect if there is a movable object
     • - Can detect if there is a immovable object
     • - Can move around a immovable object
   • Self describe criteria 1:After you move around a box say cheer and continue line following
     • - Activate speaker on robot to cheer after you finish moving around an immovable object
     • - Can detect when to play sound
   • Self described criteria 2: After you move around a box, spin around in a circle as a victory celebration and continue line following.
     • - Can spin 360 degrees in a circle
     • - Can detect when to spin around

3. Robotic Parts

   • touch sensor
     • Allows the robot to know if it is touching an immovable object
   • Motor
     • Allows the robot to move left, right, backwards and forwards
   • Light sensors
     • Allows the robot to detect what colour it is on or how dark the colour is
   • Ultra sonic sensor
     • Allows the robot to detect how far an object is from it

4. Map

   • Aproach 1
     • Start at the green zone and line follow all the way to the other green zone
   • Aproach 2
     • Start in the middle right in front of the box and line follow all the way to the green zone (either one)
