Lecture 6

tutor: Luisa Dal Pozzo

1. Lesson 8: How to do a challenge
• Example of challenge: avoid an obstacle keeping the same direction
  • initial brainstorming:
    • presentation of the challenge
    • identification of the problems
    • evaluation of the sensors to use
• divide et impera:
  • breaking up the challenge into pieces that individually raise less difficults
• preliminary steps:
  1. run straight in your direction until 10 cm from the obstacle
  2. soft stop
  3. turn 180° around the obstacle
  4. run again in the original direction
• tasks testings
• feedback:
  1. every team presents the software solutions and the obtained results
  2. common discussion
  3. pros and cons of each strategy

1. Lesson 5: More about Sensors: ultrasonic, color and gyro
• Ultrasonic sensor, accuracy and range, distance reading
  • elements conditioning the reading
  • example of wall following
• Color sensor and line follower
  • reflecting mode or color identification mode?
  • line follower (the problems of the use of only one-sensor)
  • effect and use of the proportional approach
  • effect and use of the derivative approach
  • effect and use of the integral approach
• challenge on PID line follower
