Preface
Safety Instruction
Please turn off battery power when your Robot is connected to Personal
Computer or Laptop via USB cable
Do not plug or unplug and wire or module when power is on,
Do not even touch the board when power is on or your hand has static
charge (you can move static charge by touching metal tap).
Reversing +/- when connecting modules with OSOYOO board for
Arduino, or incorrectly connecting can destroy your electronics and cause fire
hazard.
Please make sure polar direction is correct when you install batteries in
your battery box, otherwise it can destroy your device and cause fire hazard.
Please don’t use Carbon zinc batteries as power, as output current of this
kind of battery is too low and it is unable to load the robot car
Do not leave batteries in battery box if you don’t use it for long time due to
the risk of fire and malfunction.

OSOYOO V2.1 Robot car kit Lesson 0:
Introduction
OSOYOO robotic car learning kit is designed for beginners to learn Arduino
programming and get hands-on experience on robot design and assembly.
We have developed a step-by-step tutorial which evolves from a simple car
without any control to a multi-function robotic car controlled by mobile APP.
Every lesson has detailed sample code with comments, circuit graph,
assembly instruction and video. Even if you have no programming
experience, you can follow the step-by-step instruction and gradually become
a master.
Our robotic car is 100% open source. If you are an intermediate player and
have time to read our code comments, you can easily customize this robotic
car to make your own project for science fair, college homework or even
commercial applications.
This kit contains module parts including OSOYOO MODEL X motor driver
module(*), Ultrasonic Sensor module, Tracking module, Infrared Remote
Control, Bluetooth module and ESP8266 Wifi shield, etc. With these modules,
the robot car can work in multiple modes such as auto-go, infrared control,
obstacle avoidance and line tracking. You can use our Android APP to
change working mode through Wifi or Bluetooth.

*OSOYOO MODEL X motor driver module is an improved L298N module
which has newly designed wiring sockets and can greatly simplify the
assembly procedure and wire connection stability.

Basic Tutorials
Here we have prepared some basic tutorials for the users who are not familiar
with Arduino, this section will show you what Arduino is, and teach you how to
start some simple Arduino projects. Arduino is the largest open-source
hardware platform in the world and offers infinite possibilities on what you can
achieve using simple microcontroller-based products. Learning how to
program using the Arduino platform is a never-ending process.
We believe with this hardware + software support, you are able to become
expert programmer (developer) very soon. So don’t waste time, just get this
kit, and start your project right away!

OSOYOO V2.1 Robot car kit Lesson 1:
Basic robot car assembly
Objective
In this “Hello World” version lesson, we will install the most important
framework in the smart car and program the car to do some simple
movements. If you have passed the test movement of this lesson, it means
Arduino, voltage meter, motor control module, motors, batteries，chassis and
wire connections between these parts are all functioning well.
As your experiments in future lessons are all based on frame work of Lesson
One, it is very important to test the installation and sample code in this Lesson
properly.

Hardware Installation

16
Install device
1) Remove the protective film on upper and low car chassis (Each car
chassis has one protective film)
2) Fix 4 motors with Metal Motor Holders as follow (Please check the motor
derection before installing metal motor holders)
3) Fix 4 motors on lower car chassis with screw M3*10 hex screws via hex
screwdriver (screws in metal motor holder package)

17
4) Install OSOYOO MODEL X motor driver module to lower car chassis with
4pcs M3 plastic screws, plastic pillars and plastic nuts. (Please make sure
you install the OSOYOO MODEL X motor driver module in correct
direction.)
5) Install voltage meter on low car chassis with 2pcs M3 plastic screws, plastic
pillars and plastic nuts
6) Fix OSOYOO UNO R3 board on upper car chassis with 4pcs M3 plastic
screws, plastic pillars and plastic nuts. (Please install UNO R3 board at the
side with printer)

18
7) There are two kind of robot car set for you to choose to buy. The one is
with 2 battery box( 18650 battery box and 9V battery box), and the other one
is with 1 pair 18650 batteries and 1 piece battery charger for 18650. We
recommend to use 18650 batteries as the power. If you want to use 9V
battery as the power, please use rechargeable 9V battery. Don’t use Carbon
zinc battery, as this can’t provide enough current for the robot car.
A) Fix this Battery Box on upper chassis with 4pcs M3 x 10 screws and M3
nuts.
B) Please install this Battery Box on upper chassis with 4pcs M3 x 10 screws
and M3 nuts. (These are the same as screws and nuts for 18650 battery box.
If you don’t get 9V battery case, please ignore this step).

19
8) Insert OSOYOO Uart WIFI shield V1.3 onto your UNO board
Connection
1) Connect 4 motors to OSOYOO MODEL X motor driver module K1 to K4
sockets as per following graph:
