Lecture 4

date: 18 February 2016 tutor: Alessandro Memo

1. Lesson 4: Sensors (1): touch & color
• 3-levels Line follower
• comment of the proposed solution, the difficulties to adjust the parameters
• 3-levels Line follower, another solution introducing a soft/sharp control
• comment of the proposed solution, a smoother movement
• the proportional approach to the line follower, more the error stronger the correction
• example 16 (v2): test of this method, and comment of the obtained results
• PID: Proportional, Integrative Derivative approach
• example 16 (v3): PID line follower
• challenge: follow a curved line in the faster way(20 min)
• comment on the previous challenge
• challenge: sequential movements(10 min)
• comment on the previous challenge and discussion of a possible solution
• color sensor in ambient mode, simple examples
• example 18: flash controlled robot (10 min)
• color sensor in color recognition mode
• example 19: color identification, presentation of a possible solution and introduction to the array initialization
• challenge: slalom (30 min)
• comment of the results obtained in the previous challenge
• challenge: around the tower (30 min)
• comment of the results obtained in the previous challenge and discussion on the proposed solution
• short hits on the RGB mode of the color sensor
• challenge: color components (10 min)
• comment of the results obtained in the previous challenge and discussion on the proposed solution
• challenge: garbage cleaner (30 min)
• comment of the results obtained in the previous challenge and discussion on the proposed solution
• challenge: object recognition (30 min)
• only proposed
• challenge: rescue mission (40 min)
• comment of the results obtained in the previous challenge

Comments:Good partecipation and interest, expecially for the students directly involved in the incoming meeting.
