Robot Challenges

1. Avoiding Obstacles

   • Go straight
     • Get data from ultrasonic sensor
       • If less than 5cm (activated)
         • Stop motors
           • Reverse
             • Turn Right
               • Go straight
                 • Turn left
                   • Go straight
                     • Turn left
                       • Go straight
                         • Turn right
                           • Return to line (loop)
       • If more than 5cm (not activated)
         • Keep going straight (loop)

2. Moving Objects

   • Go straight
     • Get data from ultrasonic sensor
       • If les than 5cm (activated)
         • Stop
           • Put arm motor down
             • Turn right*
               • Go straight (5cm)
                 • Stop
                   • Take arm motor up
                     • Reverse
                       • Turn left*
                         • Follow line (loop)
       • If more than 5cm (not activated)
         • Go straight (loop)

3. Line following

   • Get colour data from robot sensor
     • If less than 43, turn left (motors 50-20)
       • Get colour data (loop)
     • If more than 47, turn right (motors 20-50)
       • Get colour data (loop)
     • If more than 43 but less than 47, go straight (motors 50-50)
       • Get colour data (loop)
