Today we present the FlameWheel Robot assembly tutorial and quick-start guide! It is rather difficult to assemble this robot without guidance. Feel free to refer to my introductory tutorial today.

Flamewheel (A 2WD Remote Control Robot) is part of our Education Robot Series. It is an agile two-wheeled robot with unique and innovative movement. Have fun assembling the robot yourself, while learning about electronics and mechanical principles.AssemblyThe materials we need to prepare beforehand are:
1. Models used for assembling the body~
2. Two DC motors3. Romeo BLE mini (Small Arduino Robot Control Board with Bluetooth 4.0) and a set of screws~ 4. A cross screwdriver

5. A battery box and four AAA batteries~

Now let’s start the assembling:

Step one: assemble the inner shell
Remove four boards from the mould and assemble them as follows:(Here is what it looks like when it’s finished)：Step two: assemble the back-up plate for the control board;As shown in the following picture:Step three: assemble the back-up plate for the battery box;As shown in the picture below:Beware not to confuse it with the bolt: Step four: assemble the electric motor and get it fixed;Put the two motors into the inner shell, fix the motor shafts onto appropriate positions, and plug them into the bolt as follows:Rotate the bolt to clamp the two motors until it’s completely fixated:

Step five: assemble the control board and connect it with the motor;Fix the control board onto the back-up plate with screws and connect it with the motor’s power cord:

The power line interface of the control board is shown as follows:

Step six: assemble the battery box and connect it to the control boardStep seven: assemble the wheels;Assemble the two gaskets first:Install the wheels and clamp them with washer and screws:Attention: spin the wheels to make sure smooth rotation!After installing the wheels on both sides, the assembly is nearly done.DebuggingWe need the following materials in debugging:
1. Mobile Terminal APP: ‘GoBLE’ Bluetooth 4.0 controller (the current version only supports iOS system and iPhone/iPad. Download for free in App Store)
Download link：https://itunes.apple.com/cn/app/ ... qi/id950937437?mt=8

2. Arduino IDE
Official download link：https://www.arduino.cc/en/Main/Software/
Select Windows installer to download and installStep One: Install GoBLE and Romeo.m library files
As it’s necessary to call the existing library functions from the sample programs, you need to add GoBLE (mobile Bluetooth communications App) in the Arduino library, as well as the library file of Romeo BLE mini board.

Download link for the library files:GoBLE library functions；
Remeo library functions；Method of installation of GoBLE library file:First, open the downloaded file and unpack it, find the library file and open it, copy the following three files:

Find the Arduino installation directory, find libraries file, and copy the three files listed above under this file:

Method of installation of Remeo library file:Open the downloaded file and unpack it, copy it directly in the libraries file under the Arduino installation directory: Until this stage, installation of the two library files are finished. Step two：download the sample programs, open it up with Arduino IDE as follows:
