Lecture 2

date: 28 January 2016 tutor: Alessandro Memo

1. Lesson 2: Brick I/O (completion)
• the LED under the bottons, the command (summary)
• the speaker, commands to generate tone, notes and sound files (summary)
• how to use EV3Explorer to upload the programs on the brick
2. Lesson 3: Motors (presentation ppt, see materials)
• parameters: speed vs power, how the motor controller keeps constant speed or power
• parameters: blocking vs returning, wait for the end of the command or return the control immediately to the next instruction
• parameters: control of the different speeds of two motors
• parameters: acceleration, running, deceleration
• example: up and down arm (5 mins)
• example: move straight 50 cm (10 mins)
• comment of a proposed solution of the previous example 7, the geometry of the robot, angular speed (degree) approach vs time approach; the sections of a good program, initial commenting section, variable initialization section, main section
• challenge: take an object at 40 cm (15 mins)
• example: sequence; comment of a proposed solution introducing the subroutines, global variables, particular functionality of the subroutines in EV3Basic
• turning movement using only one motor
• turning movement on the place using two motors
• turning movement of different angles using two motors
• example: turn right 90 degrees, on the place (5 mins)
• comment of a proposed solution of the previous example 10, self evaluation of the parameters
• challenge: squared path (15 mins)

Comments: Good interaction and partecipation, good results. Most of the students have send their photo (as requested) while all the students have proposed their blog. To evaluate. Time schedule respected.
