Introduction: Arduino Balance Robot


I am not the creator of this design or the programming. I am simply writing an Instructable to help others to make this awesome bot. I am a novice and therefore hopefully my instructable will help others do the same.

All information came from the following site:

Step 1: PARTS

So as for parts you will need the following:

1 x Arduino pro mini clone

1 x FTDI USB to TTL programmer for the Arduino pro mini

1 x Arduino Uno clone

1 x MPU-6050 gyro and accelerometer

2 x 2.4G wireless serial transceiver module

2 x 35mm Stepper motor

2 x Geeetech StepStick DRV8825

1 x Wired nunchuck controller for Wii

1 x Mini DC 7~28V to DC 5V step-down converter

1 x 11.1V 2200mAh 30C Li-polymer Battery

1 x B3AC 2S/3S Lipo balance charger

1 x 1/4W Ceramic metal film resistors set (600 PCS)

1 x Glass fiber prototyping PCB

1 x 3-Pin toggle switch (5-Pack)

The total cost is around $130 AUD,

However if of course you have some of these things already such as the battery and charger etc then this will cost significantly less, as these are the expensive items.

But like i said, i have searched around and this website is the cheapest by far.


DealExtreme has given me a coupon code that will give you 5% off any purchase over $10.. that will save you a heap also...

AU20170808, which is 5% Off

For products on the "Eletronic and Tool "Catalogue.

The coupon code is only available for order over $10 USD.

This coupon can be used by anyone..

Step 2: The Body

The body is fairly simple in design,

I liked what has been done already so i thought i would simply make the same.. however since we had access to a 3D printer i asked one of my students to whip up the STL files.

This made it easier to create duplicate copies exactly the same.

You could also use a CNC router if you have one..

I have added a DXF file for you to use if you have a CNC this will cut out 2 copies of your bot using 6mm stock.

The files below are the STL's you will need to make the bots body.

I also added the Autodesk Inventor files just in case you wanted to edit them for any reason.

Step 3: Machining the Parts.

So I opted to machine the parts out of 6mm Acrylic I had laying around at work.

As a ITD teacher I have access to all sorts of machines including a Roland MDX 540 CNC router.

This machine is the backbone of my design class, we can machine anything with it as it also has a rotary axis.

So I used it to make the parts and they came out beautiful.

The electronics have been ordered from they were kind enough to donate the parts I needed to make this project.

Stay tuned for the next step.
