Well, I can’t seem to help myself. I built yet another obstacle-avoiding robot. My wife’s eye roll confirms that I should probably branch out into other forms of robotics but there is just something exciting about creating something “almost autonomous”. And it seems to keep my kids entertained for a short while anyway.
I’m especially proud of this one because it is smaller than my previous creations and is less modularized so it is slightly more rugged and can handle the inevitable bumps that will occur with proper testing/playing.
The brain of this robot is an ATTINY84 microcontroller from AVR. It uses infrared to detect obstacles and has some neat little low-cost tank tracks for mobility.
I’ll break this post up into a series so I can go into as much detail about the build as possible. Check out the final product in the video below. Don’t forget to bookmark this page if you find this article informative
And as always, Happy building!
