By Damir Sakanov

• when I planning the lesson, I was guided by the fact that the children have experience working with Shero RVR

• Understand what a Raspberry Pi is

• ​children have some experience programming in Python

What can you guess about me

To swim

About me

Mr. Damir

​Children

Vоlleyball

First time

IDTech

To play guitar

Mr. Damir

• I came from Russia, Moscow

• I have Сhildren (2 girls)

• I work at Letovo School as a teacher of Electronics &Robotics

• This is my first time in the USA, I came to work at the IDTech summer camp

• This year I learned how to solve a Rubik's cube

• I taught myself to play the guitar

• I dream of learning to swim

About me

1.       Students stand in two rows opposite each other. Only one student can stand in front of each student.

2.       They look at each other about 1 minute.

3.       After that, they turn away from each other and take turns calling the name of the student who was standing opposite and answering the questions that I prepared in advance: the color of the eyes, what kind of shoes, and so on. Questions are given randomly.​

Icebreaker​

Mr. Damir

​Self driving car

​While driving, it is very important that the car receives all the necessary information from the sensors.

Mr. Damir

RVR's on board sensors include

Open Ended

After seeing a few previous slides, tell me what you would like to study?

Today we will begin work on assembling and programming a robot that will be able to drive itself, focusing on the markup

Mr. Damir

Plan

Mr. Damir

The Raspberry Pi has GPIO pins that connect to sensors, lights, motors and other devices

Mr. Damir

Raspberry Pi - is single-board computer

• 2 motors

• encoders​

• line sensor

• buzzer

• RGB led indication​

Mr. Damir

Our RPi robot is equipped

• Motors

• Buzzer​

• RGB led​s

Actuators

• Encoders

• Line sensor​

Sensors

Types of connected devices

Mr. Damir

• eight-channel line sensor

• connected via i2c bus​

• to work with the sensor, you need to install the library on the Raspberry Pi​

Line Sensor "Octoliner"

Use pins SCL, SDA to connect octoliner (GPIO 3, GPIO 2)

Pinout Raspberry Pi

To control the motors, we will use the motor driver - is PCB with L293D chip (H-brige):

​

• motor5-12V - ​board power

• ​IN1, IN2, IN3, IN4 - control of the direction of rotation and speed of motors

• M1, M2​ - connection of DC motors

Mr. Damir​

Motor Driver

To control the pins of the Raspberry Pi, we will use the GPIOZERO library​

GPIOZERO

In your Raspberry Pi has a folder with robot hardware examples.

Let's start by looking at these examples.
