Picture of Yogy - The Arduino Powered Robot Made For Kids
In this Instructable I will show you how to make a cute and kid friendly Obstacle Avoiding Robot I like to call Yogy.

Yogy gets his name from the Yoghurt tub body he is made from. I am a sucker for seeing the best in trash and this Yoghurt tub looked too good to be thrown away. I salvaged it and decided to give it a new life, a better life, a life as a robot!

You can follow through with me and make Yogy by following the written steps or pictures, which are pretty self explanatory.

Or if you don't feel like reading through and clicking with your mouse, you can check out the videos of the build with commentary!

I had problems with the library so, i add it

and the connection diagram of the HC-SR04 is missing, I know is obvious but is missing.

Thanks for the proyect t!!!

hi there, i'm having a blast building the yogy. when i try to compile the code, i get a series of error messages revolving around a "redefinition of 'Servo leftServo'. ideas?

I get an error on "NewPing sonar (TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); / / Create Ultrasonic sensor object" what exactly should I enter?...

Have you installed the newping library?
Same issue here. The Ping))) sensor combines trigger and echo pins into 1 "Signal" pin. Can't figure out how to adjust the code in a such a way to read both signals from the 1 pin. Ideas...?

I was wondering if i can turn this onto a dog toy...it's possible?
chickenparmi (author)  rpinto91 year ago
Of course it's possible, anything is possible. First you would need to waterproof the body, so the dog could take it outside. It might be a good idea to add cushions or something similar around the outside to give the dog something to grab onto. You could even have a small servo inside the bot that lets out dog treats. Good luck!

Hi, very nice project.
I've made many robots like yours by the past but due to a huge lack of time, i've stopped.
When i see a so cute robot like this one, it make me to think about finding some spare time to restart this activity.

Nice project! Did you do this with kids already, or is it a prototype?
chickenparmi (author)  ynze1 year ago
Already done with the kids :) I have a 3yo sister so she was the first candidate to play with it. Its nice because the tub encapsulates and protects it all, so little hands can't pull out cables. If you add a SNES wireless controller, which I will make an Instructable for later, it makes it really easy for them to control too.
