Well that was cool. But the page doesn't exactly have much in the way of words. Despite the spammy nature of the newslamp.com domain --and despite the spammy nature of the youtube video being in response to Katy Perry's Part of Me music video-- any idea what microcontroller is being used?

EDIT: And now this video is rocketing to the top of reddit, number two at the moment. Video is on liveleak.com. Way to give the actual producer credit, internet.

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)?

aspensmonster2• 13 years ago

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 infuriating.

And judging by bradleyjoyce, it looks like there's more technical info to be found, albeit in a language I don't understand.

This robot is made by Japanese amateur roboticist Hinamitetu.

There are lots more acrobatic feats on his YouTube page:

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 signal rising and in (up, down, left, right) the boundary position. (With a threshold detection value zero gravity fall detection circuit and rising that). I was triggered by a combination of (H, L signal using the threshold as zero gravity detection value) of H and the raw signal, L signal. Based on these signals, and to determine when to stretch or bend the leg.

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!

A little more background on this would be interesting.

And it even stuck the landing. Very cool.

thejsjunky• 13 years ago

Literally, a different robot but it looks like he puts adhesive gel on the feet to help the landing: http://www.youtube.com/watch?feature=player_embedded&v=mF9_2...

Looks like this is the link to the original video at the creators account. http://youtu.be/4M0jhAuAuJI

Here's one by the same guy that is even more impressive. Several robots do double flips and then grab the bar again!

The sound when it goes slow-mo is my new favorite ambient/drone track.

GIFtheory• 13 years ago

Cool, but not as cool as this, which was done in the early 90's: http://www.ai.mit.edu/projects/leglab/robots/3D_biped/3D_bip...

OP's robot was made by a guy at his house. That's the difference. Imagine where we'll be in 20 years.

It'd be really nice if a mod could edit the URL to the actual content creator, so that s/he gets some YouTube likes and subscribes.

jnbiche• 13 years ago

Agreed, can a mod pretty please edit the URL so the actual creator gets credit?

future_grad2• 13 years ago

Success!

that is sweet. when do the robot Olympics start?

WA• 13 years ago

Love the trashy surroundings with all that junk on the left hand side, little curtains and whatnot. Reminds me of Sci-Fi movies from the 80s :)

future_grad2• 13 years ago

Nice submission history, evab. Newslamp, newslamp, newslamp, newslamp. Post the original content.

DanBC2• 13 years ago

Just for fun, here's some graphs. (http://imgur.com/a/dlhna)

PS: Thanks mods, for editing the URL!

mromanuk• 13 years ago

Really impressive. How many backflips a human can do?

restlessmedia• 13 years ago

I would have marked him down for his build up but the execution and landing get top marks. Amazing.

I like this video called "Bloopers" featuring some of the successful bot's older family members. http://www.youtube.com/watch?v=F7eUvuruw7E
