To be fair, there have been far more interesting posts on HN that were ignored because it was only a YouTube video. Would you be commenting if it wasn't linked to a different site (however spammy looking the domain)?

Of course! I wanted to know the micro-controller used :) Looks like gilgoomesh has a direct link to the creator's actual youtube account as well, not the embedded rip-off from youtube user chrill22, which looks like a typical view farmer. It looks like chrill22 took hinamitetu's "Quadruple Backflip(NO.16)" video, trimmed out the part where hinamitetu was setting the robot up, and then re-upped it. Absolutely infuriat…

That, I'm not too sure of, but it's more than likely a PIC-16 or 18 series.

There's a nice write-up from last year on using a PIC16F628A and four servos to build a walking robot. http://www.academia.edu/1767517/Walking_Robot_with_Four_Serv...

If you're the tinkering type, it's quite an interesting read. Of course, that's a long way away from a robot that does backflips ;)

This robot is made by Japanese amateur roboticist Hinamitetu. There are lots more acrobatic feats on his YouTube page: https://www.youtube.com/user/hinamitetu?feature=watch

Google translate of his about page on youtube: I used a 2-axis acceleration sensor. Is located in the head it. It then measures the gravity mainly. The measured value, by the angle of rotation will change me. --- I will zero gravity measurement value measurements of the axis when the axis of the sensor was leveled to the ground ---. Position in the rotation I was divided into four regions. To detect the falling signa…

Am I the only one who read that like a poem?

When I saw the guy setting the robot up in the original video, I realized that it's quite a bit larger than I initially thought.

Still, pretty damn impressive!

No. It's beautiful.
