Otto DIY Class Final

Introduction: Otto DIY Class Final

This project was made possible by Otto and Athens Technical College.

To start, you must first purchase the kit from:

Then follow the steps at:

Step 1: Step One: Assemble Robot From Instructions

This website is where you will find assembly instructions and code for your Otto robot.

As you can see, I mixed and matched different parts and colors, and used a portable charging block for power instead of the recommended 4 AA batteries.

My speaker is mounted on the front for easy hearing and a sword is attached to the right side for decoration.

Step 2: Step Two: Plug and Code

After your robot is assembled, load up Arduino IDE on your computer and plug in your robot.

At this point you should have the Otto files downlaoded. Export them directly into your Arduino libraries folder.

This will allow you to use the code that Otto has given you.

Step 3: Step Three: Finish Coding

Once your libraries are extracted, you will need to go into Arduino IDE and make sure your bootloaders are up to date.

Set your board to Arduino Nano, your processor to ATmega328P (Old Bootloader), and your COM to whichever port you plugged your robot into.

Once this step is done and your code is ready, press the upload button in the top left corner of the program to upload the code to your robot.

Step 4: Step Four: Watch

Watch your robot's sick moves and dope singing voice.

Depending on what code you used, you can make your robot sing, dance, or avoid obstacles.

This project was written with the avoid code:
