Class flow

1) In this course, students are supposed to deepen their understanding through online lectures and practical assignments using sensors and a microcomputer at home.

2) We use OCW-i and Slack. You can find Slack invitation on OCW-i. Immediately after your registration process, please check OCW-i.

3) You will use Arduino and breadboard. Please prepare Arduino software and MATLAB software in advance (note that the installation can take up to 2 hours).

Course schedule/Required learning

	Course schedule	Required learning
Class 1	face-to-face class Introduction of various sensors Practice using Arduino and CdS cells Parts distribution (RC servo motors, battery boxes, resistors, CdS cells, photo-reflectors, male and female jumper wires, header pins)	1) Take photos of three types of sensors used in daily life, paste them into Word or PowerPoint, etc., add comments about the sensors (name of the sensor, physical quantity to be detected, etc.), convert them into a PDF file, and upload the file to OCW. 2) Install the Arduino hardware support package for MATLAB by referring to the following site: https://jp.mathworks.com/help/supportpkg/arduino/ug/install-support-for-arduino-hardware.html#bvfxo09 or https://jp.mathworks.com/videos/install-the-matlab-and-simulink-support-packages-for-arduino-106497.html
Class 2	Online Class: MATLAB practice https://www.mathworks.com/learn/tutorials/matlab-onramp.html	Upload MATLAB Onramp Certificate (PDF) to OCW
Class 3	Online Class Signal processing (ensemble averaging, moving averaging) Basic MATLAB signal processing practice (graph display) Connecting MATLAB and Arduino to display the output of CdS cell on MATLAB	Perform an experiment to measure an everyday object using a sensor (the detail will be explained in class). Connect MATLAB and Arduino, and graph the sensor output on MATLAB. Paste the graph (or screenshot) into MS Word, and add comments, such as what you noticed in this experiment. Convert the word file to PDF, and upload the PDF file to OCW.
Class 4	Online Class Signal processing (Fourier transform, power, phase, continuous and discontinuous, Gibbs phenomenon, window function) Signal processing practice using MATLAB	Using MATLAB, perform a frequency analysis of the measurement results obtained in the previous assignment. Paste the time domain graph and the frequency domain graph (power spectrum) into a word document, add comments (such as what you noticed in this measurement experiment) Upload the PDF file to OCW.
Class 5	Online Class Systematization technology (A/D converter, sampling theorem, aliasing) Fabrication of a line tracer using a photo-reflector and RC servo motor #1	Make a circuit using photo interrupter on a breadboard to detect a line. You will also build a line tracer that runs along the line by moving RC servo motors based on the sensor values.
Class 6	Online Class Line tracer fabrication using photo interrupters and RC servo motors #2	Line tracer fabrication
Class 7	face-to-face class Line tracer driving test	Everyone bring his/her own line tracer and drive it on a predetermined course to compete for time.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

There is no textbook. Class materials will be uploaded to OCW-i. (OCW-i will be crowded during or just before class, so please download them in advance.)

Reference books, course materials, etc.

Fundamentals of Measurement System Engineering (in Japanese), Chikei Nishihara and Kazuo Yamafuji, Morikita Publishing Co.
Prototyping Lab 2nd Ed. (in Japanese), S.Kobayashi, O'Reilly Japan.

Assessment criteria and methods

A comprehensive evaluation of the assignments given in the lectures will be conducted.
