Objective

Welcome to the first lesson of Osoyoo Model-3 Robot Learning Kit!

In this “Hello World” version lesson, we will install the most important framework of the robot car and program the car to do some simple movements. If you have passed the test movement of this lesson, it means main board, 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 the frame work of Lesson 1, it is very important to test the installation and sample code in this Lesson properly.

Hardware Installation

1. Remove the protective film from the chassis:

2. Install the motor under the chassis with M3 Hex screws and nuts as follow:

3. Install the universal wheel with the M3 Hex screws and copper pillars:

4. Install the universal wheel under the chassis with the M3 Hex screws:

5. Install OSOYOO UNO Board on the chassis with M3 plastic screws, pillars and nuts:

6. Install the battery box on the chassis with M3 Phillips screws and nuts:

7. Plug the OSOYOO Motor Shield Board in OSOYOO UNO board：

8. Install the voltage meter on the chassis with M3 plastic screws, pillars and nuts:

Connection

1）Connect OSOYOO Motor Shield with the motor:

More detail about OSOYOO Motor Shield, please refer to this link:

2) Connect OSOYOO Motor Shield with the battery box:

3) Connect OSOYOO Motor Shield with the voltage meter:

4) Install the wheels:

Now hardware installation is almost done. Before we install the battery into the box, we need to upload the sample code into OSOYOO Basic Board for Arduino first.

Software Installation

Open-source

Software(IDE)

 Download IDE here:
https://www.arduino.cc/en/Main/Software?setlang=en
7 zip is a free zip
utility that un-zips zip files		 Download 7zip here for free
https://www.7-zip.org/

Step 1:

Install latest IDE (If you have IDE version after 1.1.16, please skip this step).

Download IDE from https://www.arduino.cc/en/software, then install the software.

Step 2:

Download https://osoyoo.com/picture/2WD_Car_V2.0/code/lesson-1.zip , unzip it, you will see a folder called lesson-1

Step 3:

Connect UNO R3 board to PC with USB cable, open IDE, choose corresponding board/port for your project.

Notice: Shut off your battery or Unplug your power adapter when upload sketch code to OSOYOO Basic Board for Arduino.

Step 4:

Click file -> click Open -> choose code “lesson-1.ino”, load the code into OSOYOO Basic Board for Arduino, and then upload the sketch to the board.

Testing

Disconnect OSOYOO Basic Board for Arduino from PC, please confirm that the power switch of the OSOYOO Motor Shield is off, put a 9V battery into battery box.

(make sure polar direction is correct, otherwise it can destroy your device and cause fire hazard).

Put the car on the ground, turn on the switch of OSOYOO Motor Shield,  the car should go forward, then go backward, then left turn, then right turn, then stop.

If the car does not move as per above mentioned result, you should check your wire connection, 7 jumper caps on OSOYOO Motor Shield, battery voltage(must over 7.2v).
